Valiant Golok : intial impressions, mainly descriptive

I finally found some vegetation that made using a coarse finish worthwhile. I had to process a large amount of rhubarb and trying to do press cuts or slices with the fine polish and it was not effective. I could not do it without using excessive amounts of force. When a more coarse edge was applied the slicing ability increased significantly and the cutting was done in no time. This was after it was harvested of course. The collecting can be done with a very fine edge as the plants don't grows in large clumps like I was trying to cut them, and of course you can swing with much greater speed than you can press down into a cutting board. Jimbo, combinations of differening vegetation can be bothersome indeed. We don't get anything like that around here, but we do get Alders growing which are very soft and springy and inter-growing through and around pine and spruce. When the main trees die you have a soft and spring wood wrapped around a hard core, that requires some care to cut and makes axe work difficult, this is where a long blade like the Golok would be really appreciated.

Cleaned profile :

Using the Golok with the even finish, it was difficult to tell if the cutting ability had increased. I simply don't have anything of that length that cuts as well as it does, and thus I can't make a definite comparison. It obviously didn't lose any ability. Using it again on some medium class limbing, the edge again dented near the top (12" from choil), similar to what was described before, but this time it was on harder work. Specifically this was limbing dead trees that I was clearing out of a lot. The wood was small (two to three inches at base), but the limbs were rock hard. I was limbing them as easy as I could.

Heavy work :

Before I moved on to the harder limbing I slapped the blade off of a log a few times to check the stiffness, wrist snaps from a few inches, and the blade would take a permanent bend. I just hit it on the other side to straighten it out. I then headed for the worst wood to cut, dead limbs on standing trees. It was cut it in the worst way, just slamming the blade down hard and sweeping the limbs off. The edge near the top (12" from choil) took heavy ripples right away. Within a dozen or so swings there were multiple ripples large enough so that they could be seen at arm's length. I continued to do this for about 500 swings. The dents grew until they were past 1/16" out to the side, and then the edge broke away as the ductility was exceeded. The handle cracked on the other side somewhere during this cutting, the depth of the crack was about 1.5" .

I then moved onto chopping in the region from about 3" to 9" out from the choil. This area of the blade is very hard and resists damage very strongly. I again went through another 500 hard swings and all I did was induce one very small dent. You would have to look very carefully to see it. It was about half the size of the one described for the tip for the light limbing. I then tried to work the very tip of the blade to see how that would handle the same work, but since the wood was very ingrown I was hitting the damaged region (12" from choil) frequently and the blow outs were increasing. Near the end, steel was lost from the edge for about one and a half inches. The damage extended to to about 1/8" deep, the blade was ~0.060" thick at this point. I stopped here as I felt the handle give.

I then went back to the log I was slapping in the above and wrist chopped straight down into it about 25 times. Short chops, just a few inches of drop. The handle gave with each chop and the blade fell out on the last hit. The tang is indeed sharp on the back which is probably what induced the cracking in the first place. It is nice and thick. I then viced the blade in a stump and bent it to 90 degrees. The blade bent easily and took a set right at the vice point with no curvature in the rest of the blade. I then pushed it past 180 degrees. It bent then at the secondary point where it was wrapped around the stump. The edge cracked up to 1/2" deep in the region of the first bend which was the same place that it got heavily damaged in the limbing. In retrospect that was the worst place to do a flex test and it would have been useful to check the edge after the 90 bend.

To do a simple hardness check I took the Cold Steel shovel and chopped it into the false edge and into the primary from the choil to the tip. The shovel chopped into the false edge readily, with no damage to itself. The tip was harder, but the shovel still damaged the blade far more readily than itself, up to 1/8" deep fractures. Hitting the fully hardened area of the blade, the Golok did as much damage to the shovel as it took, only ~1/16" deep. Moving past this and heading towards the choil, the blade is again very soft and the shovel slices into it just like it did on the false edge. On the walk home, I chopped the edge into a few rocks and a concrete block (holding onto the tang), this did little damage to the fully hardened region, much less than the shovel chopping, and just tended to mash it in.


Profile :

The profile is pretty much perfect on the primary edge. The blade cuts well and yet has a low binding rate. It could be improved as Jimbo noted by forming the edge all the way down to the handle. The sharpened top edge, I would forget. It is too limiting in regards to overall functionality, and requires that the spine be hardened to make it durable enough to form an efficient cutting profile. The hollows in the primary could be cleaned up, but this would take a long time, and the user can do this themselves, so it is a matter of where you want the price to be.

Hardness :

The tip and the choil area should be harder. The tip needs the hardness for cutting, the choil could still cut with its much lower hardness as you are generally only going to be slicing with it, but is very difficult to form a crisp edge there when it is so soft. If this could translate into a durability issue then of course leave it softer. It also might effect shock damping in a negative way which might not be a good trade off. I would prefer a spring tempered spine to increase blade stiffness.

Handle :

The grip has grooved rings, decorative probably, and like the similar features on khukuris some will find them abrasive, however due to the very extensive shaping, the grip should be secure even without them. I meant to sand them off and see if the handle got to slippery, I don't think it would.

Scabbard :

This is basically a slip case, it would be nice to have a way to actually wear this. I would not go too complicated. The rig that Camillus has for the Patrol Machete is fine.

Summary :

In short, this is a blade that can approach the whittling ability of a SAK, cuts as well as a machete on soft vegetation with a very powerful draw cutting ability, and get penetration in the same class as a quality hatchet on thick wood with a fluid pace. The grip is secure and ergonomic, and the blade durability and edge retention is very high in the fully hardened region.

[Some of the above cutting is very dangerous, even if you know what you are doing. It is not intended to describe safe usage, or testing procedures. All work was performed either by, or under the supervision of, a professional maniac.]

Lots of good points! I think that we're getting somewhere. I'll ship out an untouched spare so that you can get an idea of how it compares to the first. It's unselected - just out of the box.
The one thing that's missing in the review - or that I'm not seeing - is a comparison between a regular chop at 90 degrees to material, and a pulling or sabering cut. I know that Singularity has gone over things with his pictures, and that you commented there. It is a big point though for people just starting out with a long blade and the blade curvature and handle that will allow such a cut. Cutting through something easily - that you expect the blade to only cut into - could pose some hazards. It'll also explain some of the comments on just what thickness can be cut through, in a given material. While this is a function of user ability, it is applicable just because few blades in my experience will work with it.
The nylon webbing available at Canadian tire works well for an over the shoulder strap.
Off to post and then cut wood. More later..
Oh - I had no luck on finding a decent Iltis - but I'm going to Prince George in a couple of weeks - should find one there.
 
Cliff,

I think this is impressive. As I read them, your destructive tests confirms what Jimbo and I found through more normal use.

We know now what there is in these blades, let's use them ;)

Sure these blades are excellent for draw cuts, and certainly more efficient this way. The only word I can say is beware, draw cuts are surprising.

As a side comment, too bad for those that do not appreciate your tests (to reference some recent threads), I've learned a lot on the Golok "internals" with your help.

Thanks & Cheers,
 
Draw vs straight cutting :

Why you do draw cutting as it requires more motion, and is a far more complicated cut thus there is a lot to go wrong and takes longer to learn. First off all, since you are drawing the blade across the material being cut you are inducing a slicing action and the difference between a slice and a pure push cut can be huge depending on the aggression of the edge, a many to one effect. If the edge is very finely polished, the effect of a slice can still be seen, but isn't huge by any means. Take a very fine polished blade and push it through a piece of rope, and then slice across it to cut it, and gauge the force used, they will be similar. However take the same blade and put a rougher edge on it and repeat the cutting. This time you will note a huge difference, many to one.

So unless you are running coarse edges you can forget draw cutting? No, because there is yet another factor. Along with running the edge along the material being cut (the slicing action), during a draw you also change the angle at which the blade is being presented to the material being cut. This is as Singularity pointed out the reason why guillotines had blades at an angle, it is also the same reason for skew chisels (why felling axes have curved edges) . This angle during the cutting has two main effects. First off all there is a pseudo-slice action so it is complementary to the above, but mainly it concentrates the force generating a much higher pressure. Materials will be cut (ruptured actually) when the blade contact generates a pressure which is higher than what is holding them together, thus by enhancing the pressure at a given amount of force, you cut the material much easier, and it is the start of the cut that is the hardest.

Basically you come in with the blade at an angle so only part of the edge hits the material being cut (this is fairly easy with the above Golok as the tip is upswept). As the blade starts to cut through the material you both draw the blade towards you and rotate it forwards so that it works at an angle (this naturally happens with the Golok again because of the upswept tip) . The first thing you will note in doing this (aside from the greater cutting ability) is that the impact force that you feel is vastly reduced. The reason for this is really simple. The longer the blade is in contact with the material, the lower the impact force produced. It is the same principle as if you were driving along and slammed on the brakes or just applied them slowly. If you are just making a few cuts, this difference can't really be felt to be that significant, but it will add up over time.

Jim, I'll see if I can't be more concrete in the comparison with the next one, it should not be difficult to compare the cutting ability with a straight heavy wrist torque as compared to a draw cut. There are other aspects which I left out of the above such as the rigidity of the material also has to be considered, as if it isn't above the impact force generated the material won't be cut, it will just be moved or bent, which limits power used in straight cutting, draw cuts are also faster due to the inherent rotation of the blade etc. .

Singularity, thanks.

An excellent explanation! I'd agree with Singularity that we're really getting into the fundamentals of the goloks and why they are like they are, and what they're capable of.
If others are less appreciative - good for them. Everybody knows where I'm coming from.
Now off to grind wedges and get some wood in - busy times!
 
The new Golok .

Handle :

The first thing I noticed was the difference in handle length. The new one is almost a full inch longer (~2 cm) than the previous one. There is also a difference in the finger grooves. This one has four shallow ones, while the last one had three more prominent grooves. The new pattern fits my hand much better. The end bulb on the old one was also much larger, but the new one still looks easily secure. The handle thickness is near identical, it is about 1 1/8" across at the top, compare this to my SHBM which is only ~0.825". The large width reduces the pressure on your grip and makes the blade feel much lighter in hand, which is kind of deceptive power wise.

Blade grind :

I set the callipers to 0.01" and slid them along the edge and they went way up just as they did before (~0.03"), very similar grind profile. The blade is seated much tighter to the handle, and the top edge is centred. The edge is also well sharpened from tip to choil, no blunt spots, catches thumb nail along the entire length. There is just a hit of a secondary bevel near the tip for about one cm, like it was off angle on the buffer for a second or similar. The blade is straight and seated perpendicular to the handle.

QC seems to be signifiicantly higher on this one.

Previous one, Scabbard durability :

I had intended to do this earlier but forgot about it. I first took the scabbard and flexed it lightly across my leg. Under low pressure it took a crack across the bottom. I then put it on the floor and walked on it and it cracked under my heal readily. I then gave it a short swing and whacked the top off a 4x4 and the top cracked. It isn't very durable in regards to impacts, even Kydex when cold is tougher. However it does work well as a simple slip sheath.

Cliff:

Wandi or Federico are probably the ones to speak definitively on this subject, but I don't believe that the scabbards/sheaths on Indonesian blades are very durable by tradition. Light wood construction seems par for the course on most of the ones that I've handled that had scabbards. The scabbard on my Survival L has developed several cracks that I attribute to changes in the weather. No biggie from my perspective.

I spent most of Friday, and all day Saturday and Sunday clearing the yard at my new place. I used the Survival L to chop bushes, vines and small trees (living and dead). I also used it to dig roots and slice rope and cord. It was quite the learning experience. The blade held up to everything, even a hit on a stone, with only minor damage. I'm sold, though I would follow Jimbo's advice to "go slow" when using these tools. Their ability to cut cleanly through the target is surprising. It would be very easy for that surprise to be a nasty one.

Wao, good, Spence, generally first use of this blade is like "wao", it surely did it for me. It seems you had fun! :D

If I was you, I'd epoxy the cracks: insert screw-driver, force epoxy in it, remove screw-driver, and press for some time.

Wandi strongly advises never to put fingers under the blade's edge, even when holding the scabbard.

I have discovered years ago in shipshandlers kevlar and spectra sail repair tapes, they are like duck tape, but made of kevlar, much more expensive, but quite useful for bullet-proof repairs. Lining the inside along the edge would certainly prevent some problems of shock-splitting.

Mmmm I am not sure iron-wood is light wood, quite the opposite actually. Wandi told me the wood is from old deutch houses roofs, but well indonesia is not really dry, so it seems to move. Mine is still shrinking...

Cheers,
 
One of the concerns I had was with scabbard durability. We're into new territory here, with wood, even if the Scandinavians and Indonesians aren't. Mine have held up remarkably well and there are no cracks in normal use - but then I live in a pretty damp place.
Naturally most people into survival aren't too concerned with pretty, and presented with anything fairly rigid are likely to be wrapping with extra cord, rawhide from a dog's chewey - just about anything imaginable, that's likely to come in useful.. So I don't worry too much about the sheath itself. If I get to - then I'll make a wax impregnated leather sheath.
The point is well made though that there's a special way of holding the blade and scabbard, withdrawing the blade, and so forth.

I'd say that the blade you have now matches what I have in several blades. It wasn't "selected" in any way - I just grabbed the unused one. The only thing I did was to have a look at the scabbard which you'll notice is a different wood - and has a narrower belt loop. Basically I like the old design better.

I'm still waiting for the arrival of the Sumbawa - and using that longer blade with a little more weight should give me a good idea of whether more length and weight would be a good idea for the survival golok. From using the tip heavy parang, I'm inclined to think that the SG is optimal as is for most, as safety concerns come up for inexperienced users - as pointed out so many times... Other than for the false edge and tip hardness, I'm finding the SG perfect for my purposes, and it works well as is.
 
Wow is right, JM.

Thanks for the idea re: sail repair tape. I was going to do an epoxy fix and then, maybe, a wire wrap. But the kevlar tape sounds interesting.

By light wood, I meant thin. I can understand why Wandi is insistent about not positioning the fingers below the blade when drawing it. A cut-through is definitely within the realm of possibility.

Jimbo: My area is damp in the summer, too, but perhaps not as damp as Indonesia. I was surprised by the cracking, but again it's no major issue to me.

I'll go back and re-read the earlier posts on this thread, but tip hardness hasn't been an issue for me, so far. I agree that the false edge is not useful. I'm of mixed minds about a thicker, longer version.

I found that the Survival L was plenty long (too long in many cases, given the confines I was working in) for just about everything that I did. The only exception was when dealing with some thorny vines and canes - a little more reach would have been nice.

But, it was too light to make much progress on several dead, dry cedar and oak limbs (all under 3") that I dealt with. I ended-up using a khuk on some and a bow saw on others. I'm wondering if a heavier Survival S or Kelapa wouldn't be the ticket for best all-around use.

S.
 
Spence,

I actually use the kevlar tape for a lot of applications, a pain it is so bloody expensive...

There is another fix you could do against scabbard splitting, it is the epoxy resin filling : But you need a stratification quality, very liquid resin, hard to find...

You must be talking of a parang then, longer, more forward weight, more general weight, a much longer and heavy swing than the survival... The Parang Borneo I have fits your description.

Jimbo, how many Survivals do you own now?, are you planning to be the canadian reseller for Wandi :)

Cheers,
/JM
 
Maybe I'm lucky with my scabbards. I deliberately left off the tung oil treatment to see how they changed through settling in.
The only reason for proposing a longer survival golok is for work on limbing - and where I need to chop through brush and still have chopping ability on larger and harder wood. Any of the regular ones is fine for a regular large bush knife - and the shorter kelapa of about the same weight serves the purpose of a shorter blade as is.
Hmmmm ... Every time I want a blade and they're sold out - I do ask where the last one went.... I hear that you ask the same question JM..
 
Jim, in general, the answer to the last question is "a customer from canada", and each time I know who he is....

Ah ah ah! :)
 
As long as we grab all of the good stuff before they get popular..
I got the Sumabawa today and Suwandi had also included a small horn sheathed golok. I'm looking after a friend's house for a few weeks so I have to limit my testing tonight on my drive over there. I'll certainly be playing tomorrow. Both blades are absolutely stunning - obviously the Sumbawa is because of the size and damascus, but the smaller blade is so well proportioned that it's going to see a lot of use. The carving on the handles and scabbards is amazing.
 
Jimbo:

Did you get the Sumbawa small or large? Also, I was wondering why? The blade shape seems pretty straight, rather than the curved golok. Will it be as efficient, I wonder?

I have a package on its way, too. It'll be the last for awhile, I'm afraid - though that's what I said about the last one. I'm expecting a Klewang Maremu (which I now doubt will see much use - too long), a Golok Sunda 2, a Survival S, and a damascus bowie/khanjar. Wandi's last package took 7 days to reach me. Today is a week since he shipped, so I'm hoping it'll be there when I get home on Friday.

S.
 
By the way, I have been playin a lot with the Naga recently, and though it is a good looking knive, you'd be amazed of the performances of the 12 " blade, after a bit of sharpening (and little edge profiling). The edge seem to keep the sharpness as on the survival. Light and fast, excellent grip, and what a handle:

I'd be interested by your comments on the Klewang Maremu...
 
I got the Sumbawa large. It's a well balanced blade, despite the size:
