I used to keep a Classic Swiss Army in my frame bag. After having it close on my finger a few times, I realized I needed a knife with a locking blade.
I got a Leatherman Style CS as a gift and like it well enough. I've been carrying it around, but will likely not take it on my next trip (there are lighter ways to bring scissors along). Its blade does not lock either.
Now I'm trying to decide on a new small, keychain-carry style knife.
I'll hold off on the one I'm leaning toward until some of y'all have chimed in.
Which knife is in your handlebar bag or jersey pocket while touring?
