I received these images of an old Tru-Balance Knife Company catalog that I’d never seen before. It turns out that they come from Bobby Branton, a longtime friend and student of Harry K. McEvoy.
The hand-writing looks like Harry’s (but so does Stephen’s a little) so I think it was before 1993. But I know it was after 1984 obviously by the dates written on it.
This is a great resource because it gives dates that certain models were in production.
