This is one fantastic butterfly knife. Benchmade makes great knives and this is amazing. It has a 154-CM stainless steel blade. The handles are made from milled titanium and have a skeletonized frame style. One of the really nice features of this knife is that it has a titanium latch (with a spring to keep it open while you play with the knife--that way it doesn't bash against your handles while you are working your butterfly magic). It also comes with a nice nylon sheath.
Blade: 4.20" Overall: 9.4" Weight: 4.1oz
