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.

Solid. My first Benchmade product, and I'm very impressed by the quality. The AXIS locking system holds the blade firmly in place when deployed. The knife is very sharp for American D2 steel and has no problem cutting through thicker materials. The deployment mechanism for opening and closing the blade is as smooth as butter, and really is the best I've used. If you want a small knife, this isn't for you. It's much larger in size than it looked in the picture, but it still fits comfortably in my pocket and the clip seems to keep it in place well.I had a laptop HDD sitting around, so I pictured it with the knife to help you get an idea of the size.

Color: Serrated Edge/Sand HandleVerified Purchase
Where do i start... I have purposely held off on rating this because i wanted to give a good honest review. This blade is everything i could ever ask for in a daily carry. I am a bigger guy 5'11" 250 and this fits me perfectly. Comfortable, forget its there.

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!

First read about this knife in a review written in a recent magazine I receive (USCCA). The raters gave it top marks so I thought I would give it a go. Having had many knives over the years both in the military and now in civilian use, I was excited to own a "Top Flight" military style knife. It actually arrived earlier than promised and after opening the package I was amazed at just how well it is built. Sturdy and very well balanced. The pocket clip is black which conceals well in just about all color of pants. The pocket clip is also reversible if you wish to carry the knife in your other pocket. The instructions are very clear and recommend the knife be carried only with the clip on the correct side for safety. This is one blade you do not want going unsupervised in your pants pocket. The blade is a D-2 flat black blade with an AMAZING edge...so sharp it actually astonished me right out of the box. With other knives I have purchased in the past, there was always some "reconditioning" of the blade required before it was really ready to carry, but not this one. I actually showed it to my son who is a surgeon and he was very impressed with its quality and especially the edge. The screws are also black and contrast very cleanly with the handle. I cleaned the mechanism (manufacturing and shipping particles) and very lightly lubricated it IAW the manufactures suggestions, now the blade swings very easily and quickly locks precisely into place. The handle contrasts the large and beefy blade with its Dark Earth color...very striking. The holes in the handle fit my fingers as if it were custom made just for me, three holes on each side. Serrations at the top and bottom of the inside of the handle on both sides also aid in control. The blade locking mechanism is stout and very positive. No doubt when your blade is locked with releases on both sides of the upper handle. When the blade is extended, it locks with out so much as a wiggle in place, very positive locking, no hang-ups that might spell disaster if the un-locked blade were to retract towards a miss-placed finger. All things considered, I love my Benchmade Adamas Sibert knife! Can't live without it. Won't go anywhere without it. If you are looking for a stout, extremely well built locking blade, that will handle just about whatever you can throw its way (Never throw this knife or any knife)...then this is the knife for you. It is worth every penny spent and expect years of service from this artisan crafted beauty. You whip this out of your pocket and people know you carry the BEST!

This is the sort of knife that gets handed down through generations.

The grip material is nothing short of amazing. Even when wet it's easy to hold and secure. It opens easily (some say too easily) and the axis lock is secure and robust. The blade itself has no side to side play as on cheaper knives. The blade material holds a great edge and was razor sharp from the box. I don't really "test" my knives so much as use them, but doing some regular work around the yard and house which included cutting rope and boxes, removing twigs from branches to make plant runners, slicing up a few mangoes, and other miscellany it performed well. Maybe not better than a fixed blade knife which is my preference (usually a Gerber LMFII or a KaBar machete) but it didn't have the shortcomings of a regular folding blade. I.e., I wasn't worried about it closing on my fingers or breaking. In other words, up to this knife I'd always used a fixed blade despite it being somewhat inconvenient (can't run to the hardware store without removing it, etc.).

Sharpening this Sibert is a different story. It's not the easiest blade to sharpen on account of its hardness and blade shape. Be extra careful to set the proper grind angle. Don't let this detract from the knife however. Cheap knives are easy to sharpen, but easy to sharpen means they don't hold the edge all that long.
