I carried a big folding jackknife every day of my life, including right now. An Uncle Henry (I am very partial to Uncle Henry) Pappa Bear, these days, like most days. Right now I carry that jackknife, a multitool, and a little rancher-style 3 blade sliver-gitter penknife all the time.
Just cuz a feller has a knife don't make him bad... It's the murder that makes him bad.
