That's a nice one, Guyon!
I just picked one up today in excellent shape. It's a later version with so-so fit and finish, but it was unsharpened and lightly used. I put a nice mildly-convex edge on it and it's scary sharp now. The following is a scan, not a photo, so the blades look kind of dull and gray:
When I was a young kid, I only remember ever seeing two folding knives in the house (my dad was NOT an outdoor type or the least bit mechanically inclined). They were both in the tomato basket my dad used as a tool box. One was a cheap Barlow pattern, and the other was an electrician's knife. Even as a young boy, I could sense the elelctrician's knife was a quality item while the Barlow was of low grade, like most of my dad's tools.
It's funny that I never had an interest in picking up either of these patterns until lately. The Camillus will satisfy my desire for the electrician's pattern. I haven't thought too much about a Barlow, although I've looked hard at Northfield versions from Great Eastern Cutlery.
Stay sharp,
