I've carried the Champ for decades and don't understand why everyone doesn't carry one. Used every tool again and again. My awesome knife collection consists of that one knife (well it's one more than practically everyone else in England) and it's terrific. Why would you limit your tools at hand?
The size is no problem; carry it in the watch pocket of your jeans or a belt pouch.

It's the knife in the lower right of the first pic on this thread. Don't know what the other one is and can't find it on the web site.
