Knife making - Hand made pocket knife

This my my 23th hand made pocket knife. I finally got my new bench grinder. about 3HP. I really enjoy it and am looking forward to getting descent at free hand grinding! Furthermore, I made a lapping tool, so I can now make bushings. In the past I have sometimes peened the liners so tight that the action of the blade when going from locked to open was compromised. Now the walk and talk are getting better!
