Dexter, this is one of 35 or so folders that Chris Reeve made before he dubbed the knife "Sebenza". The screws do indeed thread into the handle slab, which are of a thicker stock than currently used. The lock bar is shorter and wider, and the D2 blade is narrower than on the older style Sebenzas that I have. I understand that the early handmade Sebenzas also used this stock of titanium for the handles.
