"A Knife With Backbone"!
john l.
Great knife! Solid and very sharp. Looks badass, too. Feels good in the hand and easy to carry in jeans or cargo pants/shorts. Only issues: (1) The pocket clip was very tight, but I fixed this by loosing the screws a tiny bit. (2) I wish the thumb studs were just a bit larger, but that may just be me. All in all another winner from Benchmade. I have one of their butterfly knives (for over 25 years) and an AFO (over 10 years), but I think the Adamas is my favorite. I will buy the automatic version next (or the Presidio, or maybe both. Lol.)
The Juggernaut of knives!!

This knife is an absolute Beast! It has quite a hefty weight to it so some may feel this knife is only fitted for a certain use but I tell you what I carry it everyday and I have no issues. The blade is tough as hell and holds an edge incredibly well! The axis lock is smooth and I've never experienced any issues whatsoever with it. I have literally chopped down a 4-inch diameter tree with this knife just to test it and the edge was just as good as when I started and the blade showed no sign of Wiggle afterwards. If you're looking to fight an entire Army, chop an engine block in half, and cut cinder blocks with ease this Benchmade is for you! What a monstrous folding knife!
My Benchmade 275 Adamas...

Tell you what buddyrow- this Adamas is one off the scales tough hard use knife! From the moment you pick it up you feel as though you could pry elevator doors open with it (just a figure of speech...don't try it -you'll get in trouble -LOL !) Anyway..the fit and finish is impeccable and the D2 blade is typical Benchmade hair shaving sharp! I don't find the 7.7 ounce weight to be a deterent to EDC and everyone who sees my 275 admires the great craftsmanship.I'm very happy with my Adamas that I purchased from BladeHQ (those guys and gals provide some of the fastest shipping I've experienced...if you are thinking about getting a mega capable tactical (ie, workhorse) knife look no further than the Benchmade 275 won't regret it--Mike V.
