Himalayan Imports 18" Ang Khola Extreme Testing

I've been making noises about posting this for a few days now, but I just couldn't get into a review-writing mood, if you know what I mean. I'm actually glad I put it off now, because I managed to retrieve the pics I took so you'll all get the full effect. Anyway, on to the review!

I was fortunate enough to snag two Himalayan Imports 18" Ang Kholas for the price of one thanks to the incomparable Bill Martino. There was one caveat to this deal however; he wanted to see some extreme field testing, which can be pretty insane when you're talking about knives that weigh nearly 2 pounds. Naturally, I wanted a piece of this action :cool:. I was not disappointed. I got two different models by two different kamis; a standard handle AK by Sher and a chiruwa (full tang) model with finger grooves by Kumar, Sher's brother. Sher and Kumar have very different styles, which has been a topic of discussion before on the Himalayan Imports forum. Sher is renowned for making thick, heavy, massive choppers, while Kumar is best known for inventing the lightest, quickest khukuri in HI's lineup, the Kumar Kobra. This was my first sample of Sher's work, I have seen Kumar's work before in the form of a 16.5" WWII model, my impressions of which can be seen here. Here's a breakdown of these two beauties:

Kumar's blade: I was instantly intrigued by this knife because I had never handled a chiruwa style khukuri before. The finger grooves which Kumar cut into this one were far too small for my fingers, they needed to be enlarged by about 50% in order to be comfortable for me. This has been a problem in the past as the average American has much larger hands than the average kami. Still, it wasn't too hard to enlarge them with a bastard cut half round file, and the end result is pure heaven. While I worked on the finger grooves, I filed the edges of the tang even with the handle scales. I think the scales shrank considerably after they were pinned on, because the tang was uniformly about 1/32" wider than the scales. I figured this could be a comfort issue so I took care of it before using the knife. Other than those issues, the handle is great. It really fills up my hand, much better than my other khukuris. It's especially nice in the pinky finger region, which I'll expound upon later. Below is a pic of the handle before I did any work on it. As you can see, the finger grooves are pretty small and placed too close to the bolster for comfort.

The balance of this knife is magical. Kumar is known for making very lively blades, and this is no exception, even though the design is intended primarily for chopping. I think that the chiruwa handle improves the balance immensely, keeping it from being too blade heavy. The balance is still solidly towards the blade, but it's still maneauverable in my hand. The blade is very well forged, I only noticed one little indentation towards the tip, and it had the same problem at the tip as my WWII. It was shaped oddly, the last 1/4" of the edge didn't follow the same curve as the rest of it. Here's a very crude illustration, it's exaggerated but hopefully gives you the idea.

In addition to all of that, the edge was dead dull. I tried to chop into a cardboard box and it only mashed it down. I've been getting a lot of HI's like that lately, it's disconcerting to say the least. I'd really like to see these khuks being shipped with servicable edges, it gives a bad impression to newbies and makes it harder to put a razor edge on them.

Sher's blade: True to form, Sher's blade is noticeably thicker and beefier than Kumar's. The balance is much more blade heavy, it feels very dead in my hands. The blade is immaculate though, I get the impression that Sher is much more meticulous in his forging and finish work than Kumar. The handle on his is much smaller in diameter though, and does not fit my hand nearly as well as Kumar's. The blade also was unfortunately very dull, sad to see on such a fine knife. I of course felt obliged to correct the situation immediately, and managed to put a decent edge on it with sandpaper and elbow grease. It wasn't the finest edge I've ever put on a khukuri, but it would cut much better than before.

The sheaths on both knives are about the same; servicable and much better than some I have seen, but not too flashy. They both hold their charges very securely and look to be pretty tough, not much more to say here. The karda provided with each khukuri is also very well done, they're big enough to do nearly any task that could be asked of a small knife and are well finished. The chakmas are equally large, and seem to be properly hardened as well.

Now, on to the good stuff! When I saw that Uncle Bill wanted some heavy duty testing performed, I decided to give it all I had. I decided that I would 'sacrifice' Kumar's khuk to the really rough testing; I figured if it was destroyed, I still had one khukuri, I had just now paid full price for it. I doubted I would be capable of doing it serious harm though, but I set out to try anyway.

Before I did any work with either khukuri, I put a razor edge on the Kumar blade and a so-so edge on the Sher blade. Kumar's blade was slightly less blunt to begin with, and for some reason I just had better luck sharpening it. I put a convex edge on both of them for sharpness and durability. I decided to leave Sher's blade at less than optimal sharpness to see how much it would affect the chopping ability compared to Kumar's blade.

My first test was very simple and very short; I took both blades into the woods along a path I have cleared out to ride ATVs on. There are lots of fallen trees, springy underbrush, and thick grapevines in this particular area of the forest. It made for a nice variety of material to cut with each khuk. I started off trimming back the underbrush with Sher's blade. These are what I and my family call 'prickerbushes'; they can have a thick, tough central stalk, but the ends of the plant are 5'-7' long whippy little vines with monster thorns. They're very difficult to cut because they aren't very rigid but are very tough. The Sher made Ang Khola would cut them, but it took very careful aim and a lot of effort on the springy little vines. When I switched to the Kumar Ang Khola, however, the job became much easier because it was so much sharper. It still wasn't ideal for the task, but it was much better than it's duller companion. I only cut with these for a few minutes each at this task because I didn't have much time, so handle comfort wasn't a big issue. Below is a pic of the entrance to the path, you can see the deadly 'prickerbushes' lining both sides.

GOMPH-IMG_1655.JPG


Next, I started taking swings at the grapevines. These also provide a unique challenge as a cutting medium because they hang from the tops of the trees and are often 1.5"-3" in diameter. They basically shrugged off all but the best-aimed swings from my 18" Ontario machete, back before I discovered Himalayan Imports. My Gelbu Special does a fair job cutting them as well, but I've never gotten it as sharp as the Kumar Ang Khola was that day. Kumar's blade cut those grapevines like a lightsaber through butter. As long as I swung with my full strength and aimed the edge properly, it could cut 1.75" grapevines in one cut! Even 4" vines could be cut with four or five properly placed chops. Sher's blade didn't fare quite so well in this arena either, but it cut the grapevines better than the prickerbushes. Again, I'm sure this could be directly attributed to the dullness of the edge. Here's a few pics of the kind of damage that Kumar's blade inflicted:

NJFCW-IMG_1660.JPG


The vine in the following pic had already been cut, making it more difficult to cut again since a badly aimed swing would just make it deflect off of the edge and swing away. I found a downward angled chopping motion to be the most effective way of cutting these vines.

BMYMV-IMG_1661.JPG


At this point the mosquitos were driving me totally bonkers, so I decided to hurry and wrap up my testing for the day. I found a ~11" diameter log that had been down for a long while, but was still solid about 1/2" below the surface. I chopped into the log with 50 full force swings using both Kumar's blade and Sher's, and the results were very surprising to me. I had always read on Bladeforums that the chiruwa style khukuris transmitted more vibration while chopping than the standard models; I found the opposite to be true, greatly so. Kumar's blade chopped out a about 4" deep notch, while Sher's blade only managed a notch approximately 3" deep. Much of the difference can be attributed to the superior sharpness Kumar's blade, but a lot of the credit also goes to the handle comfort. Every one of the 50 chops I made with Kumar's blade was full force because the vibration transmitted to my hand through the handle was very slight; in fact it's the most comfortable khukuri I've ever chopped with. Sher's handle, however, vibrated so much where my pinky finger was gripping, towards the end of the handle, that I nearly dropped the khukuri on the first swing. It was excruciating. I had to choke up on the handle to prevent it from shattering my pinky finger, but my hand kept slipping backwards towards the swell at the end of the handle. I couldn't chop with it nearly as hard as with Kumar's blade, or as comfortably. I think the main reason the chiruwa handle was more comfortable was it's large diameter, especially in the lower half of the handle. I don't think it vibrated less than the standard handle; I think that because my pinky could grip the last half of the handle so much more solidly the vibrating handle didn't hit my finger so hard. My finger absorbed the vibration rather than being struck by the vibrating handle. I was very surprised to find the chiruwa handle so comfortable, as I had never wanted to try one before because I feared the uncomfortable vibration. Nothing could have been farther from the truth.

Here's a pic of the notches made in the log with each khukuri. The one on the left was made with Kumar's blade and the one on the right with Sher's.

WXRGO-IMG_1665.JPG


This light workout didn't really have any effect on the edges of these two khuks; both were just as sharp coming out of the woods as they were going in. I even cut myself on Kumar's blade while cleaning it! The edge sliced right through the paper towel I was using and took a small chunk out of the top layer of skin on my index finger. I used each of their chakmas to burnish them anyway and set them aside until the next round of tests.
 
We're going to move onto the extreme portion of my testing now. I'd like to clarify what I had in mind while I was performing the following tests. I intended them to represent exaggerations of real world situations. There is no real reason to use a khukuri to do any of the following things, but through carelessness or as a last resort one could be called upon to do any of them. I'll stop stalling now; here's what I did and how the khuks fared.

I only used Kumar's blade for this portion of the test; remember that I decided it would be the sacrificial lamb for this round? I only chose it because I like it a little more and was curious about how well it would perform. My plan was to cut up some progressively harder materials and see how much damage they did to the edge. My brother recently put together a demolition derby car, so I had a few rusty car parts to chop up. I chose a piece of the tailpipe and what I thought was a section of the brakeline. More on that later. The other materials I gathered up were a long coil of 1" diameter coated, twisted aluminum cable and a few pieces of a broken cement block. The aluminum cable was actually composed of many smaller wires twisted together, for the purposes of this test I'll just refer to it as the aluminum cable. Just for kicks, I filled a two liter Coke bottle and a 32 oz. Gatorade bottle with water to try cutting soft targets while the blade was still sharp.

I used a wooden chopping block as the base for all of these cutting tests; it was just a 1.5' diameter log that we use to chop up firewood. It just gave me a solid base to set all of the materials on during the chopping tests and performed flawlessly ;).

First, I tried cleanly cutting the water filled Coke bottle. Notice I said 'tried'; I hit the bottle with the edge crooked and only succeeded in knocking the bottle five feet across the yard. I did manage to nick it so most of the water leaked out, but really it was a bad cut. I tried a few more times and finally managed to slice it mostly in two; this test is much more difficult than it would seem at first glance. Next I set up and swung at the Gatorade bottle, this time I swung with an angled downstroke with much better results. The bottle was cut cleanly in two and I felt a lot better about myself. Mission accomplished, the bottles were vanquished and now it was time to destroy the fine edge I had put on this beautiful khukuri.

Pics of the bottles, before and after they met with "my little friend" ;) :

LQEVY-IMG_1781.JPG


Next I got ready to begin with the hard targets, then I realized I had forgotten something. A quick trip to the garage remedied the situation and I was ready to begin. See pic below.

QOXVX-IMG_1792.JPG


I may look like a fool with those big goofy glasses in that pic, but I've still got both of my eyes thanks to them. They didn't have to deflect any random projectiles during this test, but I'm still glad I was wearing them.

Moving on. The first of the hard targets I cut was the aluminum cable, since it was actually the softest. My first chop wasn't forceful enough to cut the whole way through the cable, so I took a harder swing. I heard a solid THUNK! and a small chunk of the cable flew 20' through the air to land in the tall grass under our apple tree. So I repeated the process three more times and each chop produced the same result, with very little damage to the edge. It wouldn't shave hair anymore, but it was still plenty sharp.

Pics of the cable chunks I could find:

QYQBF-IMG_1790.JPG


Next, I moved on to the tailpipe. First I tried to chop into it broadside like I did with the cable; the effect on the tailpipe was minimal. Basically I put a big dent in it, the edge barely bit into the metal. I was a bit disappointed, but the edge wasn't badly damaged so it wasn't all bad. Then I decided to stand the tailpipe on end. That met with more success, both in cutting the tailpipe and damaging the edge. The following two pics should illustrate the damage fairly well, basically the edge was knocked out of alignment where it met with the tailpipe but the damage wasn't extensive or severe considering what I had just done with it.

Khuk vs. tailpipe pics:

PNMDK-IMG_1800.JPG
 
At this point I decided to cut the rod which I thought was a piece of brake line. I figured that with it's smaller diameter and relatively thin walls, the khukuri should be able to cleave it in two. Turns out what I thought was brake line was a solid piece of support rod. All the khukri did was make a little bright line, the rod however put a good sized dent in the edge of the khukuri. I struck the rod at an angle, so the edge deformed to the right, when holding the edge upward. It was misaligned by about 1/32", pretty impressive really. It could have easily fractured or chipped, instead the metal just stretched and the edge remained intact, just misaligned. I was extremely impressed with it's performance on this unintentionally rough test.

Khuk vs. rod pics:

GPNGC-IMG_1807.JPG


After the rod I moved on to the toughest test, a chunk of cement block. Now, I realize that a khukuri isn't intended for use as a demolition tool, and the purpose of this test wasn't to prove that it is. I wanted to see how well the edge held up to these kind of extreme impacts. I've run into situations before where I hit hidden objects, like cement blocks, while clearing brush. I think that it's useful to know what kind of damage such an unforseen impact could inflict upon the edge. With this goal in mind, I made twelve full force chops into the concrete block, striking at opposing angles, the same type of motion I use while chopping wood. This puts additional lateral stress on the edge, making it more likely to deform and possibly chip out. I'm calling them full force chops, but I may have been holding back a little bit because the vibration caused by striking the block was pretty severe and I didn't want to lose my grip. So maybe they were closer to 80% force chops, still pretty powerful blows considering the weight of the khukuri. The damage to the edge when I was done was substantial, but not as bad as I had expected. The edge had become even more misaligned and was very badly blunted, but none of the deformations extended back into the edge more than 1/8". The edge didn't chip nor did the metal tear apart, it just stretched and indented. Considering all the abuse I had just unleashed on it, it looked pretty good.

RIJTP-IMG_1811.JPG


At this point I decided it was time to wrap up the test. Then I thought about it a little more and decided to test the tip strength by stabbing it into a stump and trying to bend it. I tried, but the tip just tore apart the wood of the stump and generally looked none the worse for wear. I was a little surprised to find that the edge still had a little bite to it when I chopped into the stump to take photos however. So I decided to do a little more chopping to see just how badly damaged the edge really was. Below is a pic of the results of 50 chops into a partially buried telephone pole.

LNGQM-IMG_1822.JPG


As you can see, it actually chopped pretty well! I was amazed considering how badly blunted the edge was. Closer inspection revealed that there was about a 1.5" section of the sweet spot that had not made contact with the concrete block. It looked like it was only used to chop up the aluminum cable, and was still pretty sharp. Even so, the misaligned and blunted portion of the edge had to have been doing some cutting as well. Although the edge had lost nearly all of it's slicing ability since it was so blunt, it could still make the chips fly pretty handily.

Next I decided to try bending it one last time, just for kicks. I put the last two inches of the blade into my Dad's bench vise and clamped it in as tightly as I could. Then I threw all of my 145 pounds into the handle trying to flex the blade. I swear I heard the khukuri laugh at me. It had a right to, because the farthest I could flex it was about 3 degrees. It just wouldn't bend. This is one knife that you can use as a prybar without hesitation should the situation call for it.

TYQEO-IMG_1824.JPG


And that concluded my testing. I would have liked to do some more cutting and edge retention tests on softer materials, but my vacation was fast drawing to a close and I ran out of time. Still, I came away astounded by the toughness of this knife. It withstood abuse that should have left the edge in pieces, and even managed to retain a good deal of it's chopping ability along the way! I'm still working on restoring the edge; it's going to take a lot of work since I have only hand tools to do it with, but the profile of the knife shouldn't be too badly affected by the metal removal. I've already filed out the misaligned portion of the edge, now all I have to do is restore the convex bevel. Thank you Uncle Bill and Himalayan Imports for the opportunity to test such a fine blade, my appreciation for what khukuris can do is even greater now that I've thoroughly thrashed this one.
 
WTH! Crap. It appears that even with my paid account I managed to overload my Villagephotos account. That's infuriating. Sorry to have this happen guys, I figured it wouldn't be a problem since I do have a paid account. I'll have to upgrade ASAP, until then I apologize. It should reset sometime soon, then they'll become visible again.
 
I've just finished updating this with a fewer smaller pics to make it more dial-up friendly and to keep it from overloading my account once everyone starts to log on here in the morning. I'm afraid it looks like it will still overload the account sometime today, but tomorrow it should be all right with the smaller pics. This sure has been a learning experience in posting pics, looks like it's time to just buy some bandwidth of my own and make a webpage. Thanks for looking everyone.
 
RR
Great review! Confirms again that HI blades are the best Khuk's available! That test should have destroyed the knife but it kept coming back for more. :D
 
Great review RoadRunner!
That was a nice comprehensive review. You used a good variety of test mediums to prove out the blade. Job well done!:D :cool: Just more reasons that I love the HI blades!!
 
As for sharpness, I agree that in general it is very important. Any forum member will easily be able to deal with a less than perfect blade NIB, and will know it isn't a sign of quality. However for someone who hasn't spent a lot of time on the forums, getting a blunt khukuri NIB could easily be interpreted as a sign of a low quality product.

Plus some people just find sharpening very difficult and would be just very frustrated not being able to use a blade NIB and having to spent a lot of time and effort in sharpening it. The solution would be to have some kind of apprentice kami just doing only sharpening. This is a *MUCH* less damanding task than forging, handle fitting, or sheath making so it should not be difficult to implement.

Nice job on the review, text and pictures. You might want to update some of the above once you fully sharpen both blades and thus comment on the relative performance when this difference is eliminated.

-Cliff
 
Well, thank you once again everyone for your kind words and comments. I feel that it was well worth the effort to find out what these blades can do.

Cliff, good point about how the uninitiated may have interpreted the dullnes of these blades. Although. many people have very low standards of sharpness and probably wouldn't be as disappointed as I was. Several friends of mine who have handled my khukuris were amazed that they were so sharp considering how large and thick they are. They seem to feel that such a big blade doesn't need a sharp edge, which from the results I got obviously isn't true. Even taking into account low standards of sharpness, these probably would not have been acceptable because they weren't just dull, they were blunt. It's also a big issue because the last four khuks I got were like this, and many others on the HI forum have made similar comments. I like the idea of having an apprentice do all of the sharpening, I'll have to run it by Uncle Bill so he can kick it up to Pala. They don't need to shave hairs, but the bevels should meet.

I'll be sure to add updates the next time I make it home and give these blades a workout again. I don't know if I clarified that before; I did all of this while I was at home in Pennsylvania a few weeks ago, so I won't be able to put in an update for at least a month or two. I *might* be trading off the Sher Ang Khola at some point, as it just doesn't fit my hand well. It's the only khuk I have so far that hasn't made much of an emotional impact, so maybe it would be more appropriate with someone else. In the interest of research though, I won't let it go until gets the chance to play on a level field with Kumar's blade.
 
Roadrunner,
excellent test. No surprise as to the results as they are nearly indestructible and by far the best Khuk's on the market. Lifetime warranty also helps doesn't it. I chopped 2 full chords of wood with my 18 incher and it was none the worse for wear in fact it still looked new. I also chopped a chord of wood with the 15 incher and even though it took longer it was still way more efficient than any hatchet of equal weight. I attribute this to blade geometry and excellent steel, not just design. Also more edge lineal length to maintain the edge longer.
 
I would think that a lot of the performance advantage of the Kumar blade on springy or hanging material would be lighter weight and consequently greater speed. You rely on the inertia of free standing/hanging targets to allow the blade to apply force to the target. If your blade is moving slower it can't apply as much force. With a target that is heavy or backed up by the ground you are not as speed dependent. It is interesting that the heavier blade had vibration problems that reduced its performance under the conditions where it should have excelled. You should try some experiments to try and locate a sweet spot on the Sher blade that minimizes vibration.
 
Jeff, you may be right about the speed advantage of Kumar's blade, it was certainly a lot easier to maneuver than Sher's. It was also considerably sharper though, which I think was it's main advantage. About the vibration, by choking up on the handle I could get away from it, but then my swings weren't nearly as powerful. Plus, the handle kept on slipping through my hand, which meant I had to stop to reposition the handle again. I think the handle's shape was the main problem, the bottom half was far too small for my hands to grip comfortably. I thought about getting a new handle made for it, but since I like Kumar's version so well, I think I'll just trade it for another khukuri once I've properly sharpened it and done a fresh comparison against Kumar's blade.
 
Great review! As a newbie to khuks, I agree with you about dull blades. I recieved a dull 15" AK from HI, and was surprised that it would come that way out of the box. Every smaller knife that I've bought has arrived razor sharp, so I was expecting the same from the AK. I have to wonder why they're not being sharpened. Are the kamis in that much of a rush, or is there a reason? I supposed different people may prefer different degrees and/or types of sharpening, but I would have liked the AK to have had a serviceable edge out of the box so I could use it without immediately having to sharpen it.

chris
 
chris, it confuses me too, that the kamis would send them out so dull. From some recent browsing I've done in the FAQ, I get the impression that they aren't what we would call sole authorship pieces. There are several different people involved in the different stages of construction, so the kami who forged the blade may not do the finish work. If that's the case the finisher would probably also be responsible for putting on the final edge, and isn't doing a very good job of it. Hopefully the issue can be resolved somehow.

I also wanted to post an update about this khuk's restoration. I've filed out all of the dings and waves from the edge, and brought it back to a razor edge using the techniques presented in Pendentive's sharpening CD. I unfortunately do not have a belt grinder, so I had to do it all by hand. I used a rubber sanding block and 60 grit sandpaper to restore the bevel, then worked my way up to 2500 grit paper and a polish-loaded strop to finish it off. There are lots of 60 grit scratches left on the blade, but the edge is very polished and shiny. All told it took me about three hours to restore the edge by hand, with power tools it would have taken less than half that. So in the end, the Kumar Ang Khola sustained no permanent damage and is now back in action. Look for a rematch between Sher's blade and Kumar's in about two weeks; I'll be going home again and taking the Kumar Ang Khola and my sanding block with me. I'll put a razor edge on Sher's blade then take them both into the woods again to see how they compare.
 
WOW!! I'll bring this back up as I had missed it till the passaround linked it.
Kurt that is a RIGHTEOUS test and review. Pics, writing. I wish I could do as well.
THO you're crazed to put the blade thru this torture :) :)
Nicely done
Tom
 
Why thank you :) . I'm glad you liked it. I'll admit I had second thoughts when I got ready to chop into that block for the first time, but now I'm glad I went through with it. Just don't do any of that on the pass-around, OK :p . That was a once-in-a-lifetime experience for this khuk, it's found a special place in my collection now.
