My brother-in-law is a big Gerber fan. He got me a folding paraframe knife. You can open it with one hand with a little practice. Pretty sweet.

It has a secure clip to hook it to your pants pocket. Gerber makes some excellent knives. I haven't done the research but you can prolly spend as much as you want.
