The Benchmade 770 Satin Plain Knife Carbon Fiber - Pre-Production Folding Pocket Knife. Benchmade produced 1000 Pre-Production Model 770's such as this one, each numbered. This is #0835 of 1000. The Warren Osborne designed 770CF Carbon Fiber has the Benchmade Axis-Lock and is exceptionally light with its carbon fiber frame. No longer in production but an excellent gent's sized everyday carry - or a nice addition to a Benchmade collection. This comes from a private collector and although the papers and box are included the knife is in excellent unused or carried condition.
