I work at a grocery store and do a lot of cardboard box cutting and opening. I have a box cutter to do my work, but where's the fun in that? Lately I've been carrying a Opinel #8 and/or a Case Sway Back Jack in Amber bone and CV. I've just gotten into the whole knife thing in the last few months. I really like the wharncliffe blade on the swayback jack for tape splitting and cutting corrugated cardboard, because the low point allows for easy piercing. I'd like something a little more robust though. I guess I'm just looking for a wharncliffe fixed blade that won't break the bank (around $100 or less). It doesn't have to be fixed and it doesn't have to be wharncliffe, those were just my initial thoughts. Suggestions?
