I recently had a chance to pick up two vintage but NIB electrician's knives. I'm in my mid-30's and I vaguely recall seeing knives like these in the hands of actual electricians and technicians pre-Leatherman era but I don't know much about them. Can anybody offer any historical info? Origins, major manufacturer(s), etc.?
I'd especially like to know (1) do they all have a locking screwdriver blade as a matter of course? and (2) Are they supposed to be insulated in some way? Mine don't seem to be insulated and I'm not going to find out for myself.
Schrade Imperial electrician's knife - grip seems to be Zytel-ish, and the screwdriver blade locks with a kind of linerlock (even though it also has a backspring)
Colonial electrician's knife - scales are solid Delrin (?) and bolsters also appear solid. As with the Schrade Imperial, this knife's screwdriver has a liner lock with backspring. Partially-serrated blade.
