The AFO II 9051SBK has a BK1 black finished drop point style blade with a partially serrated 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.

Perfect Beast Auto
Matthew H.
It's awesome buy it, but get the plain edge and don't overheat the spring. GREAT knife!

I have been carrying my 9051SBK every day for probably at least 8 years now. No blade play, perfect lockup. Comes with the superior (better than BK2) BK1 coating. I wish I had gotten the plain edge as this blade is too nice to waste that much space with serrations. But its only $30 or $40 to have BM put a new blade on it. Don't overheat the spring and it will last for years and countless thousands of openings. When it finally does give BM will fix it and sharpen and tune it up for free. The blade geometry is perfect and really showed me how important a factor that is for performance. This thing is a beautiful beast. I can't recommend it enough.
