All knives are given names, but only a handful of names really define what the knife is all about. The word "Adamas" in Greek translates to unconquerable, invincible and unyielding which is precisely how the Benchmade Adamas line-up was built. Custom knife maker Shane Sibert designed the Adamas series to honor the courage and commitment exhibited by our fighting heroes. In addition, a portion of the proceeds from these knives are donated to Three Rangers and the Navy SEAL Foundation--both of which assist the members and their families. The Benchmade Adamas automatic knife features Benchmade's auto AXIS system which is a fully ambidextrous operating system utilizing a dual pull tab method. This model, the 2750BK, features a semi-skeletonized machined black G-10 handle with full stainless steel liners, integrated spine safety and incorporated rear lanyard hole. The drop point blade offers almost 4" of raw cutting power and because of the size, this knife comes with a MOLLE compatible nylon sheath and malice clip for multiple carry options. Made in the USA.

Benchmade 2750BK Adamas Auto AXIS Knife
The Benchmade Adamas knife uses the extremely functional and popular Auto AXIS system. Built to function equally well for right or left handed users, this system features an AXIS pull toggle through the knife handle that you pull on with your forefinger and thumb. By pulling the AXIS toward your palm, the blade triggers. A nice extra fact about this knife is that Shane Sibert designed it and part of the proceeds goes to the Ranger Assistance Foundation. So when you purchase one of these knives, not only do you get a great product, you help a great cause.

The D2 Tool Steel blade is a tactical drop point. You can pick it up with a plain edge or with a combo edge for whatever your needs may be. This particular model features a plain edge. The blade has a BK coat. It has a Rockwell Hardness of between 60-62. This is a big, 3.82" blade that is .16" thick. What does all this mean? It means you have a big, beefy blade that is going to perform under the harshest of conditions.
The handle on the 2750BK is black G-10 with full stianless steel liners. The handle is wider than many knives. It is also 4.88" long and .73" thick. Along with a comfortably curved handle belly, this all adds up to a handle that feels great in your hand as well as a handle that isn't going to slip when things are wet and cold. The handle features three holes down the middle that add looks as well as make the knife just a bit lighter. In my estimation, the Adamas has one of the most comfortable handles on the market. The knife also has a deep carry tip up pocket clip and comes with a MOLLE pouch for alternate carry.
The Auto AXIS system easily stands as one of the most innovative and functional automatic firing systems on a knife. If you haven't had the chance to use one of these, check out the video on the product page and watch how easy the system is to use. It is also reliable and strong. You can lock the blade open or closed with a slide safety on the spine of the handle. Easy, simple, and reliable--what else can you ask for out of an automatic mechanism.

I rank the Auto AXIS Adamas as an A. This beefy auto knife will stead you well in the field, on assignment or just around town. If you are looking for a hard use, reliable auto knife, you have come to the right place.
