The Benchmade Story
In 1988, we set out to make the best knives in the world — and that’s exactly what we did. We’ve grown a lot since then, and while we’ve expanded to provide tools for elite tactical operators, first responders and even collectors, our goal remains the same: make the best knives in the world.
About the Product
The Adamas folding knives have proven to be the strongest AXIS knives ever made. A thick blade, liners and G10 handle scales afford the knife much of it's strength. In addition, a portion of the proceeds from these knives are donated to Three Rangers and to the Navy SEAL Foundation; both organizations benefiting the members and families of special operations. Intended for Tactical use, the Adamas folding knives are MOLLE compatible, have a lanyard hole and a deep-carry, reversible tip-up pocket clip. They include a matching black or sand Cordura sheath with snap retention and malice clip.

The jimping for the forward thumb grip is great; neither too sharp nor too rounded, it provides the right amount of friction to keep the knife in place.
The steel is D2 steel hardened to 61-62 HRC, which provides a mean cutting edge and excellent hardness. FOR THOSE WHO LIKE PRISTINE EDGES WITH NO CHIPPING, OR WHO COMPULSIVELY SHARPEN THEIR KNIVES, THIS IS NOT THE KNIFE FOR YOU!
D2 is very brittle, and from moderate usage I have already noticed microchipping on the blade. This isn't a bad thing per se, but you'll notice a decrease in the smoothness of push cutting paper. The blade will still function exactly as it SHOULD for actual use, but if you think knives should have perfect, unblemished edges with immaculate apexes, no chips, you'd better look elsewhere at softer steels or carbon steels. D2 is also very difficult to sharpen with respect to most other steels. You'll need a DMT stone to change this edge; arkansas stones and india stones won't cut it (pun intended), but you'll see limited success on Japanese waterstones.
DO NOT use powergrinders to change a knife edge. Without active lubricant cooling, grinding will cause a localized detempering of the steel at the apex, which will soften the steel and cause the edge to roll more easily, which in turn requires more maintenance to correct. For the case of this knife, I'd suggest leaving the blade as is for a while; D2 holds an edge exceptionally well, and only requires touch-up with a DMT stone occasionally or after hard use. Again, microchipping isn't a bad thing, it's to be expected out of such a hard steel, or supersteels such as S30V, S35VN, Elmax, S90V, S110V, M390, etc. As long as the microchipping doesn't develop into actual chipping, you won't have problems.
The blade grind. The relatively shallow saber grind on such a thick blade stock is honestly awful. The bevel angle is quite large, and the secondary bevel edge makes it even larger. This helps to prevent serious chipping in the D2 which is good, but this knife is NOT a good slicer. It's simply too thick for that. Don't expect perfect feathersticks, fine whittling or notches, it's simply too think behind the edge to do that. However, if you need to chop through a stick or carve up a quick tent stake, this works wonders. It falls somewhere on the spectrum between knife and sharpened prybar.
The pocket clip. The clip is situated well on the frame; the knife sits quite deep in the pocket. To an observer, they wouldn't be able to tell you're carrying an M1 Abrams in your pocket. However, the clip itself is rather poor and soft. This has been a criticism of many benchmade knives for a long time; they cut corners on the pocket clip, it softens or bends too easily, the coating on the clips comes off with some wear (the paint has just slightly started shedding on mine after a couple of weeks, but I've seen the wear on others more worn than mine). This can be corrected with some aftermarket titanium anodized clips if you're willing to spend a bit more for the style.
This is a great knife with an excellent overall performance, and a sturdy build quality that wouldn't look out of place with a smoothbore cannon and treads. It deploys fast and smooth, and comes very sharp. My primary gripes are the pocket clip and the shallow saber grind, which detracts from the cutting ability. However, for the tasks it was developed for, like hard cutting and demolishing cardboard, particle board, wood, and even soft aluminum, it excels. This knife is probably the closest a folder comes to a substitute for a fixed blade out there. When outdoors, I typically bring an axe, a fixed blade, and a folder as redundancy and insurance. This knife makes me question that. I'm looking forward to all the work I'll put it through, and I expect it'll smash through anything I throw at it.
Once I pulled the knife out of the sheath and felt the action I was real gritty and didn't seem to want to open smoothly. I was like WTF?. So I immediately threw it on the bench to see what the issue was with the action.
Upon minor inspection I noticed that the knife seem to have some dirt or residue from assembly in the action. No big deal.
At this point I grabbed my blue lube cleaner and oil and begin tear the knife down and cleaned and re-oil the action and reassembled the knife. Voilà, problem fixed. Now the knife opens up with little to no effort and is smooth as silk.
Now that I've it working nicely I love the weight of it and style. The knife itself is HUGE which doesn't bother me one bit. Some people may not like a folder this big but I do. It fits nicely in my hands and feels great!
I would highly recommend this knife to anyone.
The overall action on this blade is butter. VERY smooth open, and mine came with perfect blade alignment. Over the course of the first 6 months, it was used heavily, for everything. From opening mail, packages at work, to screw driving, to limb cutting, to prying, and digging with a lot of uses probably unaccounted for. After 6 months of rugged use, the blade developed a hair of lateral movement in the frame. A quick tightening of the main torqx screw fixed that right up. At this time I went ahead and cleaned everything inside and out and re-oiled with one of our companies gun oils (Hoppe's Elite). After the tightening the blade was noticeably harder to open and did not deploy effortlessly with a quick flip any more. After the oil worked itself in, and about a week of more regular use the butter smooth opening returned.
Over all, this knife has seen a lot of work from me. It attended a defensive pistol and rifle course and did anything and everything i needed it to. The D2 Tool steel the blade is made from is TOUGH! Not the best at holding an edge, but re-sharpens effortlessly. After all, a blade this thick you can't expect to hold a razor edge, and I didn't. This is a rugged tool, meant to be used on the regular, and not babied like a fillet / cleaning knife. The G10 handle feels excellent, and is every bit as tough as the knife it self. The lock is butter to operate and it enormous. Just screams out STURDY. There is no flex at all in any direction when this is locked open. Blood grove in the blade I'm sure would come in handy to someone..... I have not been in the situation to test this out thankfully. In the end, do your self a favor and pick this knife up. Well worth it, and for sure meets and exceeds Benchmades expected quality. Sibert designed a winner here gentleman. Thank you!
