Been using these pocket knifes since I was kid , will not leave home without it. (I don't fly on jets) This is my ever trusty Super Tinker (I switch between the original Tinker and the Super model) If you are a handy dandy kind of guy , I would highly recommend one of these babies for a life time of uses.If the main cutting blades are taken care of , they will sharpen with ease everytime to there original sharpness. My question to anybody out there is this , Does anyone know what this tool is for ? I've asked many people over the years and they didn't know what it was , many guesses though. Somebody once said "fish hook" remover ? Hmmmm ? Anybody know for sure ? Thanks , PS , If you ever really want to treat yourself to a fine life long pocket knife , one of these will surely do the trick. Peace.
