For a good number of years a Swisschamp was my only pocketknife and during that time I used every one of its blades and implements except for that small flathead screwdriver on the backspring side.
Most used, in no particular order, were both knife blades, can opener, bottle opener, scissors, both flathead screwdrivers (at least half the time for prying), in line ph head driver (oh so sweet!), pen (20 years, still writes!), and magnifier, which got a lot of use back in olden times when I used it to examine negatives and slides away from home base (photographer.) Big frustration at the photofinisher was their loupes were always either in use or missing. The Vic magnifier's optical quality was excellent (the glass version, I don't know about current plastic), so that became my away main tool for close examination. I never could work out how to use it as a fire starter, though, but haven't given up yet. I've used the file many times to knock down ragged edges on plastic and metal, and to smooth out my fingernails.
Used occasionally but glad to have them when needed are the saw, awl, pliers and strangely believe it, fish scaler which I used only once for scaling fish and will never on this earth ever do again. However, it also is a ruler that sometimes comes in handy, and gets most of its use as a probe for poking things I can't or don't want to touch. For a time it served as a lock pick (easy lock) and has been a field expedient pickle fork.
Seldom used are the corkscrew, necessary to pull corks only twice in 20 years, but used occasionally "just because." A time or three it helped pick apart a stubborn knot and is a good place to stow the tiny screwdriver. This item didn't come standard on my Swisschamp, so I got one as an accessory which I ever used once or twice. The tweezers are better than nothing for pulling splinters, and the toothpick gets used only in the direst of dental emergencies (celery stuck between teeth, drives me crazy), but is sometimes useful to actuate tiny pushbuttons like to change the time setting on an instrument panel.
Rarely used include the package hook. Several times it helped me pick up bundled newsprint or baled straw bound with wire. The chisel has been used so seldom that I honestly can't remember for what, but it is scratched and the edge has a few small chips.
Mostly, I carry the Swisschamp in a Vic belt pouch, but sometimes dangled into my right front pocket. There, it carries okay but doesn't leave much room for anything else, like for example a hand. It's a thick package, but my XL glove size hand finds handling ease to be acceptable. The scales show use, but everything on my S'champ is right and tight. It's one of my all time favorite SAKs. I've never owned a Workchamp, so not able to make comparison.
I hope this helps.
