This is a review of the Hinderer XM-18, 3.5” model.
I got this knife straight from Rick and ordered it with the features I wanted.
I specified a stonewash blade and frame, non-flipper, black scales.
I paid $395 for this knife. If you are considering paying twice as much for one of these, then stop reading this review right now. None of the accolades apply to this knife if it costs $800.

Most of you know the general specs of this knife such as the construction and blade shape. Here are a few more detailed specs per my digital caliper and scale:
Folded length- 4.8 in.
Extended length- 8.25 in.
Weight- 5.6 oz
Blade thickness- 0.165 in.
Handle thickness- 0.54 in.

Background:

I have been searching for a folding knife for several years now that would fill my need for heavy duty / survival use. A few that I have purchased, and used, have been the Fallkniven PXL, Al Mar SERE, ZT 0200, Emerson A100, Benchmade Ritter Rsk1 w/Wilkinsgrips, Spyderco Para and Extrema Ratio BF2.

All were fine knives and proved very capable in their assigned duties.

Of course there are two other brands that have defined this genre, CRK and Strider.
These are the two brands I will compare the XM-18 to, because they represent the benchmark for production hard use folding knives. I own folders by both of these manufacturers and have used them extensively.

I have used Sebenzas over the years but never liked them well enough to purchase one.
I used an Umnumzaan after they first came out and thought it was enough of an improvement over the Sebenza to buy one.
After long term use with the Umnumzaan, I found that there were still a few things I didn’t care for.
- Slow and comparatively hard to open. Better than Sebenzas, but still not easy.
- Ergonomics. This is still a straight handled knife. Very old school.
- Beadblast finish, a CRK trademark. Scratches very easily. Not terribly important in terms of function, but annoying. I buffed mine out within months because of this.
Overall, an excellent knife, it just didn’t bring it all together for me.

I have used Striders over the years but never liked them well enough to purchase one.
The older ones were very crude and blocky. When the Sng GG came out, I was happy enough about that change to purchase one. The F&F was markedly better than the Striders I had used in the past and the ergos were, in some ways, better as well.
After long term use I found that there were still a few things I didn’t care for.
- The handle is too thin for extended use. It carries very well though.
- While better than past Striders, the F&F was not as good as CRKs.
- Function is not as smooth as CRKs, or many other knives.
Overall, an excellent knife, but it didn’t do it for me either.

What I really wanted was a knife that brought together the best aspects of CRK and Strider. So, this will be a comparison between CRK, Strider and Hinderer, in addition to the review of the XM-18.

Enter Hinderer:

I have been intrigued by this knife for a couple years. It looked like a good candidate to fill the voids that CRK and Strider had left unfulfilled.

Availability has been the major issue with this knife. But, I got one, so that point is moot now.

Here are my thoughts on the XM-18:

Size / Weight- The knife is thinner than I was expecting, which is good. It still has enough width to be very comfortable in the hand while pushing hard on the blade. This is the tradeoff with folding knife handles. Thin handle=good carry characteristics, thick handle= comfort. The Strider is one of the thinnest folders made, which is good. But using it hurts my hand after a while. The Zaan is a little bit thicker, but still not that pleasant to use for extended periods. The XM-18 strikes a good balance between comfort and carry IMO.

The weight, while not light, is definitely better than say, a ZT 0-series. Anything beyond 6oz is getting heavy in my book. 8oz,or more, is annoying to me, especially when there are high end folders that are as strong, or stronger, than those heavy beasts. Light weight and strength are not mutually exclusive; you just have to pay for it. The XM-18 is very pleasant to carry considering its capabilities.

Ergonomics / Function-
The ergos are excellent on this knife. The natural point is much better than the Zaan. The choil works well for me. There have been some complaints about the blade edge coming into contact with peoples fingers due to the size of the choil, (mostly on flippers). I have fairly thin hands so it doesn’t affect me. If a person has very large or fat fingers it could be an issue.

All hand positions are useable and comfortable on this knife. The user can easily and quickly grip, choke up and reverse positions. The jimping is in all the right places and well executed. The G-10 slab has a nice texture. The stonewashed Ti side doesn’t show scratches. The overall handle shape is great.

The thumbstuds, which are now like ZT designs, are well placed and allow easy, fast manipulation of blade deployment. The blade detent works fine for me. It is strong enough to safely hold the blade in place when closed, and allow the blade to snap open with a flick of the thumb. CRKs generally have slow deployment, (even worse with gloves), Striders feature fast deployment. The XM-18 got this whole aspect right as well. There is no fumbling around trying to deploy the blade on the XM-18, it is both intuitive, easy and fast.

The XM-18 lockbar release is easy to disengage since Rick uses a carbidizer on the lockface and got the geometry right. The Zaan excels at lock release due to the ceramic ball at the lock point, whereas the Strider took me several hundred opening/closings before it broke in. It works good now but sheesh! The XM-18 had no such break-in issues and releases easily. Lockup came in around 20%, thanks Rick! I know I’m the odd man out on this issue, but I don’t want a new knife to lock up at 50%.

The lanyard hole has been a bone of contention for many owners. However, I don’t use lanyards on any of my knives so for me it is a non-issue.

The pocket clip is reversible and feels good in my hand in either position. The little filler piece Rick includes is a nice touch. Oh yes, Rick started using Phillips head screws for the clip attachment now, so that is good.

Overall, the design and ergos of the XM-18 are very well thought out and executed. This is a modern design and succeeds in every area.

Construction:

The fit and finish is high enough quality to compare this knife to CRK.

There, I said it.

The tolerances are very precise and the function of every moving part is, thus far, flawless. CRKs are known for their Swiss watch precision and the XM-18 follows suit in this area. There is no grittiness or roughness as is often felt in Striders. Striders usually smooth out, but the break in period can be tedious. The XM-18 was fluid and smooth right from the start. As mentioned before, the lockbar works perfectly, right off the bat.

The blade is perfectly centered, and the lockup is tight. There is no blade movement whatsoever in the open position.

The blade was properly sharpened, and all the grinds are symmetrical.

All hardware is perfectly finished and reeks of quality. Every screw and spacer is nicely finished.

The blade pivot washers are Teflon and are very smooth.

The pivot is a type of bull-pivot which is similar to Striders, albeit smaller. It is probably stronger than I am, and I have no worries of breaking it.

Speaking of pivots, the Zann, Sng and XM-18, all require proprietary pivot tools. Some people frown upon this. This does not bother me at all and I’ll tell you why.
Except for obtaining the tool, which should be a part of the process in this league of knife, there is nothing bad about needing a special tool for a pivot.

I have rarely needed to adjust any pivot on a folder while out in the field. If I properly adjust the pivot at home, and put locktite on it, then nothing goes wrong afield. A continually loosening pivot is a sign of no thread locker, cheap pivot hardware, or both.

I have NEVER had to disassemble a folder in the field. The idea of lost parts outweighs any potential problem anyway.

So, sitting down at a bench to clean or adjust any knife requires tools. A proprietary pivot tool is just another tool.

The Zaan, Strider and XM-18 all have monster pivots which are easy to adjust. I would rate none as superior over the other.

The other feature common to all three knives is the use of the dual thumbstuds which act as a blade stop.

Most knives use a blade stop pin in the middle of the handle; the design has been around for decades. From Sebenzas to Benchmades, most folders utilize this architecture.
The Zaan, Sng and XM-18 do not use this method of construction, for a very good reason: Strength.

The benefit of using the dual thumbstuds as the blade stop is as follows: This quote is from Hinderers website: “The fact that the thumb stud locks up against the frame adds an incredible amount of strength to the sideways torque of the blade as the sideways stresses are being stopped by the whole handle side, thus relieving the stress that would normally be put on the pivot.” Rick Hinderer.

The Umnumzaan, Sng and XM-18 all utilize this design. It is an idea whose time has come, and these quality makers realize the benefits. So, I would rate the potential pivot strength and integrity of these three knives as equal, due to this design incorporation.

Overall, the construction of the XM-18 is outstanding.

The Blade:

This is where it get interesting, and different.
The Spanto blade design is very unique. Whoever invented it deserves credit for thinking out of the box.

The XM-18’s blade is not designed primarily as a slicer. It is not a full flat grind or a hollow grind. If you want a knife to cut cardboard at work, this is not the best choice. A Spyderco will work much better. Of course, a box cutter will work better still. I have other knives for EDC, and dress, that I bought for light usage. The XM-18 is not one of those knives. I bought it for a work tool. I don’t expect it to slice open envelopes like my Buck Waimea.

All blade designs are a compromise The Spanto blade is made to excel at specific tasks.
I was pleasantly surprised at the slicing ability. It even skins better than I thought it would due to its decent amount of belly. A Tanto blade doesn’t work as well for this task.
The blade is quite competent for woodcraft. Prying is very doable with this blade. As a youngster, I was taught never to pry with a knife. I still think that is good advice, especially with a folder. This knife blade is making me change that thought pattern though. The tip is very thick. Basically, if I had to survive without a fixed blade, this folder is the one I would want. The knife is made to survive the urban jungle as well.

The blade is just very robust and well suited for the tasks it is designed for. While never doubting the strength or capability of the Zaan or Sngs blades, the XM-18 is simply more robust.

The blade steel, Latrobe Duratech 20CV, is holding its edge extremely well. I think this steel may hold an edge better than Striders S30V, and Striders S30V is possibly the best I’ve ever used.

I have only touched up the edge on the 20CV blade. It kind of reminded me of N690CO. It seemed a bit easier to touch up than S30V. I guess my first full-on sharpening will tell me more about this steel. Sorry I can’t be of more help on this subject.

Conclusion:
I wish the lack of availability weren’t such an issue with this knife because I consider the XM-18 to be the finest hard-use production folder made today. It is rare that I buy a knife and find no faults with its intended design. It is rarer still that I find a knife that makes me forget about looking for something better. This knife has spoiled me for anything else currently available in a production folder. There were a couple other knives I had thought about trying. After using the XM-18, I ask my self “why?”

The other hard-use folders I own are going up on the chopping block, or, I will give them away to friends. As good as these knives are, they just aren’t that useful or desirable anymore.
The Umnumzaan and Sng are going into the safe, probably for a long time.

If you can find an XM-18 for a decent price, I would encourage you to try one out.
 
Appreciate the review! Hoping I can pick one up at a decent price and give it a try... The idea of having a folder that can do most things well, while being practically indestructable is an awesome idea to me... I will be selling my SNG as well once I get it :)
 
A thorough and well-thought-out review. I will say that I disagree with you on a few minor points, but they aren't significant and won't keep me from keeping the one I also got from Rick.

Also like you, I too have an Umnumzaan that will not be getting displaced by the Hinderer.

Since you got your knife directly from Rick, there is one thing that you missed in your review: a brief word about Rick himself. For me, a maker with a bad attitude, or one who gives the perception of indifference or antagonism towards his client's needs, is more than enough to scuttle the sale of even the best knives. Given how busy Rick is with everyone clamoring for one of his folders, I can see where it would be possible to lose sight of the individual clients and just crank out knives everyday without regard for those who actually buy them. However, I found that dealing with Rick was exactly the opposite of this. He was always quick to respond, happy to answer any and all questions, and was a consummate gentleman throughout the entire process. And if I should ever find myself at a show where he has a display, I will definitely be taking some time out to personally thank him for the knife. Yea, I know that sounds cheesy, but he really did seal the deal for me. :thumbup:
 
WOW, my thoughts exactly, just I didn't know how to explain it in a manner that others could understand.

Rick is one of the nicest and most professional people in the industry; I had an issue with a slipping lock bar on my XM and he promptly had me return it. Not only did he fix it, he replaced the entire locking slab, all of the pivot washers and pivot bolt and the stripped clip screws for FREE- he's truly a great one to deal with in the purchase, but for me it was a greater pleasure to deal with him in the repair of a product, because it showed his sincere passion and drive to produce an exceptionable product, the is the utmost reliable not only 75% of the time but 100%, and if something does happen Rick will be more than happy to fix or replace whatever is needed to make you happy and for him to have 100% confidence in his product and its performance.
 
I would rather choose the Strider SNG over the XM-18. I don't know why, I think I like the SNG's overall design more.
 
Nice review!

I am not sure why sebenzas are so popular. I carried one for a while and, as you mention, the knife is not very nice to use compared to the more ergonomic and smoother opening knives out there such as spyderco knives.

Admittedly, I also dont understand the concept of a "hard use" folding knife. Assuming you use the right tool for the job, the blade edge and/or weight should be doing most of the work rather than your hand or the pivot. Anyway, it's not like you'll be whacked on the head and wake up in the woods somewhere. If you are headed into the woods, it would make sense to get a fixed blade rather than a folder.

My reasoning has lead me to buy cheaper (<$70) knives for edc and learn how to sharpen them with a stone. I also have been buying cheaper, ergonomic fixed blades for extended use.

Just my 3 cents :D
 
Some people like having a knife that, if needed, can cover a large variety of uses... especially without having to worry about it's structural integrity. Some people also like having a more exclusive blade, one that not everyone has or has even heard of. Some people have jobs that might put them in a situation where the right tool for the job was the one they brought not expecting to have to do that "job". These factors combined are why someone would drop 400 dollars on an XM-18... I would...
 
I use the bee-jesus outta my xm-18, the thing's turned pretty much convex from free sharpening it so much.

I've had a sebenza and Strider SMF and the XM is by far my most favorite and used folder. I don't know what generation mine is but it's got a flipper (which acts as a very nice hand guard btw) and the standard black G-10. I don't know why but I think the steel on mine is s30v.

a bit pricey, but I haven't bought or set eyes on another folder in the 2 years I've had mine, and if this one ever dies on me (which I don't see happening anytime soon), I'm gonna try and get another one.

Great Review thanks for taking the time to let people know your thoughts about this great knife.

I feel the same about many of the points you have made :)
 
Ive always wanted to try one, but would never consider paying the inflated prices. Thanks for the review
 
All I want to know is how you got yours for $395 straight from Rick.

I have been waiting over 3 years for my order to be filled.
 
If I knew the answer to that question I would have ordered one last year!
I just cleaned my Zaan and Sng. I measured the pivot on both knives. When I break down the XM-18, I will measure its pivot and post the specs for all three. (If anyone is interested in such things)
Just an update; This knife is still impressing me. The overall action is getting better all the time. It is butter smooth, yet still locks up absolutely solid.
The F&F, design, ergonomics are really great. As someone else stated in another post, the XM-18 truly is the Love Child of CRK and Strider. It has all of the good features and none of the bad ones.
Yes, I’m really glad I didn’t get the flipper.
The 20CV blade steel is very impressive. It definitely holds an edge better than CRKs S30V, which is no surprise, I’ve always thought that CRKs S30V runs a little soft. It looks like it is holding an edge better than Striders S30V, very high marks indeed. I would buy any quality knife with this steel, which might be a good thing considering Crucibles current situation.
I am seeing a few of these surfacing on dealers’ shelves again. They are going for $475-550. Knowing what I know now, I would be willing to pay that much for one. I wouldn’t pay over $600 for one from the scalpers though. (Unless you’re rich)
I have spent a lot of money on hard use knives over the last several years looking for one that really did it all. There were always at least one or two things that I didn’t like about them. Even some $200 knives would have been keepers were it not for certain shortcomings.
I have used Sebenzas, but never like them enough to buy one.
I bought an Umnuzaan. I liked it, but I kept looking.
I bought an Sng. I liked it, but I kept looking.
I bought an XM-18. I love it.
I am done looking.
I am going to save a lot of money now.

Got to say Bearcut, you tell it like you see it!:) Also, I didn't see, but I could have looked over itl, does the blade thickness interfere any with it's cutting ability? What type of blade grind does it have? I've had a Hinderer knife before but sold it when prices got to the point that I made enough money to buy another knife. I always liked that knife.
 
Steven:
Congrats on yours!

Cutter 17:
I have a stock Gen 3, so it has a flat ground blade.

Like I mentioned in the review, if you need a knife to simply cut cardboard at work or something like that, look elsewhere, a Spyderco will work better. However, the slicing ability of the XM is very good, better than my Sng. Frankly, I’ve had saber grinds that don’t slice as well as the Sng or XM.

It’s all a tradeoff. What do you want your knife to be able to do? The XM-18 is a no-holds-barred, dish it out and take it, folder. As such, it has displaced all my other hard use folders since they don’t measure up anymore. I still have some smaller, lighter and dressier folders that I use.

Update:

I finally broke this knife down to clean it and to install the GITD O-rings to the backspacers.

Disassembly/reassembly was dead easy. The hardware is very tight and well finished.

The blade detent ball in the lockbar does roll. (The ones in my Sng and ‘zaan roll too).

As promised, the dimensions of the pivots in all three knives are as follows.

Sng- .388 / 9.85mm
Zaan- .317 / 8mm
XM-18- .250 / 6.33mm

They are all big, beefy pivots.

The washers are white nylon.
The lockface is carbided, you can see it on the face when unassembled.
The blade centered perfectly during pivot reassembly.

The 20CV steel blade holds its edge as good as Striders S30V. I think it is a bit easier to sharpen than S30V however. So far I have kept the stock geometry and haven’t thinned down the edge.
The edge does get more polished and less toothy than S30V after sharpening, which is good.
In fact, the whole blade is polished more than any stonewashed S30V blade I’ve had.
I’m guessing the new S35VN is Crucibles version of this steel. This should make knifemakers very happy, assuming they ever get the stuff.

I am seeing some more XM-18’s online now. My local dealer even has one in stock. He has had it for over a week now, so sales must be slowing down a bit.

No regrets and no disappointments on this knife. It is the best knife of its kind made.

One more thing, I was hesitant to mention this before because it was so unbelievable.

Even though the blade has no wiggle and is rock solid, occasionally, the blade will actually slowly close itself the last inch or so of travel.
No other knife I own will do that.
