I know that my experience has been seeing a lot of the clips showing in a lot of pockets, but when I see cutting being done on the job, it a way different thing. I don't know what its like over where you are, but in the past 10 years here, I've had one kitchen remodel done and one bathroom remodel. I never saw any member of a work crew doing the actual work, ripping and replacing floors, replacing cabinets, wallboard, water heater, use a one hand knife or even a SAK. The folding utility knife with replaceable blades seem to be the hands down choice of cutting tool. Husky, Stanley, Super Knife, or brand X. A lot of the pocket clips if not all I see on construction crews, grounds keepers, whatever, is the humble replaceable blade folding utility knife. Its the blue collar tool of choice.
Among the office/clerical/barista crowd, I see one heck of a lot of little red classics on keyring's dangling from carabiners clipped on a belt loop. Just the other day, at the Whataburger that we have our Thursday mens group breakfast at, the manager walked by our table and there it was; the little red keyring knife that is the worlds most popular selling pocket knife/tool. A month or so ago I was in a Starbuck's getting a mocha to go, and the young lady that was working on it, had to refill some machine and was having a little problem opening some plastic package of stuff to go in the machine/blender. Like the pull tab tore off or something. Reaches down to the keyring on the carabiner and unhooks it and there on the keyring was a little classic that she used to quickly slit the top open.
Once in a very great while, I'll see a Leatherman micra, but its rare compared to the sightings of classics and folding utility knives that have all of an inch of blade at most. Except for food service and lumber work, there just isn't that much use for more than an inch of blade. Especially going about a normal life as a civilian in an urban setting.
Now if I were John Rambo, it may be a bit different.
