The steel for this friction folding knife blade is composed of scraps I've accumulated over the last 10-12 years of making pattern welded damascus steel.  I used the "canister method' to combine several chunks of damascus steel made from scrap saw mill blades, roller bearings, leaf springs, and files.  These chunks are added to a cannister and surrounded with powdered 1084 high carbon steel.  It is then seeled shut, heated to welding temperatures and forged a number of times to make a solid bar with over a thousand layers of steel.
 
The design of this knife is inspired by the classic Higonokami Japanese friction folding knife, but is made a little more heavy duty and incorporats a nylon bushing captured by a copper rivet that acts as a blade stop in the closed position.
