I've been carrying an Izula for a couple of months now in my pants pocket and have stopped carrying a folder.

With that being said I have the Case stockman #6375 that my dad bought for me 44 years ago. It has gracefully survived what a farm boy could dish out for many years before being "retired" but in all probability could be used for another generation.
