Engraving Gallery Model 318 prototype
Engraved by Steve J. Lindsay

This knife locking design/mechanism uses a sliding lock bar and a pivoting button release.  To release the blade in this design one pulls/rolls the release back.   The blade and lock bar are made from heat treated ATS-34 stainless.  The knife handle is from heat treated 416 stainless.  The pins, T slot holders and spring are made from heat treated 01 tool steel that has been fire blued.  One of the photos below is a shot of the knife apart.  The knife is a screw together design with a great deal of thought in the design so as to not have any holes going all the way through to the outside.  All holes are blind holes from the inside.  The screws are accessed by reaching in from the bottom (into the blade opening) to set screws.  One side of the knife handle and the center part of the knife (the back block, top block and blade bushing) are milled from one block of 416 stainless and thus are one piece.

The below photos are detailed and may take some time to load.
