I do, and mine contains:
- set of hex keys, regular sizes, metric seems to do fine.
- four in one screwdriver
- small screwdriver
- inexpensive mutlitool
- knife (inexpensive folding utility sort)
- army style can opener
- bottle opener w/cork scores (and spare, I ain't taking no chances)
- knife sharpener
Hex keys come in handy not only to adjust skis and bindings but to reattach faucet handles and towel racks in rental condos. Quicker to do it myself than contact and wait for the handyman.
Screwdrivers because something always falls apart or needs tightening, and one of the somethings is going to be small, like glasses. Or somebody wants to try somebody else's skis and bindings need to be adjusted to fit the different boots.
Mutlitools come in handy for all sorts of things but has probably seen the most use snipping old-school lift tickets off jackets
I always want a knife, just a thing with me. Something will have to be sliced off or open. Modern packaging requires it.
The old army can opener is because often the kitchen utensil kit in rented condos is seriously lacking.
Same with bottle opener/cork screw.
Knife sharper because the cutlery in rental condos is ALWAYS dull beyond anything I can tolerate. I hate dull knives.
Matches 'cause they are never available when the ladies want a candle lit. And other things.
This kit - in a sturdy canvas bag - goes, of course, into a checked bag.
