My better half always has her little SAK classic on her keyring in a leather pouch sheath to [protect it from the keys. She loves the classic and has had to replace it a few times when she lost one to TSA. Now she has a purple, a yellow, and a red one stashed around as spares. For bigger things she keeps a Victorinox recruit in her purse. A fixed blade mora is in her daypack that she carries hiking, woods rambling and fishing.
Our daughter, Jesica, keeps a pink Victorinox classic on her keys as well having learned from mommy as a little girl that a sharp bade, a nail file and small scissors is handy. Two of our granddaughters are also fans of Victorinox. One niece has been collecting the different artwork classics that Victorinox has been releasing.
