What Benchmade says:
The Osborne family is widely considered to rank among the finest everyday carry knives ever created. Why? It’s slim, slick, and with premium materials and build, it can handle anything that comes its way. The Mini boasts the same material options and dimensions as its full-size counterpart but in a more pocketable profile.

S90V Premium Stainless Steel (HRC 59-61)
A true super-steel, S90V offers substantial improvements in corrosion resistance over 440C and wear resistance beyond that of any other steel in the Benchmade line-up. 

Reverse Tanto
Defined by the bevel creating an upside-down tanto profile, adding weight forward on the blade.

Carbon Fiber
Multiple layers of crisscrossing carbon fiber filaments laminated together to create a strong and surprisingly lightweight substrate with exceptional stability and style. 

Quinn Knives' take:
Benchmade has taken the great little Mini Osborne, spruced it up with S90V and carbon fiber and brought it into the upper ranks of their line-up. For everyday carry, or special occasions, the 945-2 fits the bill.
