All About Pocket Knives

Just wondering if file work was common on older Camillus knives ? I just snagged two older examples, and they have some rather fancy filing on them. One is a Camilus #69, and the other is a Sta-Sharp. I'll try to post pictures later, if the macro lens will allow me.

File work is very common on the Camillus 69 pattern. I personally own three and all three have "file work" on the liners. I put "file work" in quotation marks because I'm not really sure of the method Camillus used to produce their effect.
