The AFO II 9051BK has a BK1 black finished drop point style blade with a plain cutting edge. The handle is black anodized aluminum with a fully reversible pocket clip. Includes a ballistic nylon sheath with Malice clip.

The Benchmade AFO II automatic knife is an evolution of the 9050 AFO, one of the most practical automatic knives ever made. The improvements made to this knife are substantial. The knife is large, sturdy and built for use with an improved push button lock that is 30% stronger than the original. The AFO 2 has an over-sized firing button for easy operation, even with gloves. The 154-CM stainless steel blade deploys quickly and the 6061 T-6 aluminum body is an ideal size for a rock-solid grip and now includes a steel glass breaker tip. The open backspacer design makes cleaning and maintenance easy. The sliding safety on the back does its job flawlessly. The AFO II is a truly superior knife design in every respect.

Customer Reviews

perfect knife
michael f. on Sep 5, 2015

This knife is the finest knife I have ever owned. I have a bunch of knives, ZT, and of course a bunch of Benchmade knives, This is the one in my pocket every day all day.Fast, perfect blade centering, no blade wobble at all. Very strong and stupid sharp. There is a video of a guy throwing one of these at a tree 15 times with no damage (don't do that). BladeHQ has great customer service and will treat you right!

I love my predecessors but this knife is artwork! SOLID no wobble, solid lockup fantastic panels, feels so smooth and will easily be my new favorite knife for a long time to come. Its more than I have EVER spent on a knife but it was so worth it. Blade HQ was cheaper than other places and had stock. This was my first purchase with them, now that I have found them I'll be a LONG term customer!!
