I wanted to have a UK legal knife to carry around in my bag (mainly to cut up fruit on the go for fussy toddlers). Even though my Opinel has lost its lockring it's still a bit big to be legal, so that will stay in the saddlebag for day rides. I have resisted the lure of the EnZo PK70 (which I first heard about on here, you bad bad people), and gone for a Victorinox Waiter. I'd forgotten how handy Swiss Army Knives are - I must have a couple kicking around lost in drawers, but it's a great little tool, and cheap enough not to mind too much if it does get lost or damaged.
