I sharpen knives for a living and one of the ways I get folks to stop by my canopy at the venues I work is to sharpen pocket knives at no cost. Well, the get the sales pitch while I sharpen their knife! I see about 6 or 8 pocket knives each time I go out. Yesterday would be typical, I saw 3 Schrade Old Timers, a couple of S&W lockbacks, 2 or 3 Swiss Armies (all Vitorinox) and one Trapper style of no discernable maker. I can usually guess which type of blade is coming out of a pocket if the fellow is actually carrying one. Under 40s if carrying, have the lockbacks and over 60s will have something akin to the trapper, Old Timer, or a Barlow. Suit and ties tend carry the Swiss Army knife from the Executive series. Another observation is that many women are carrying. Mostly a small sheath knife. Easier to get it out and running if needed.
