i believe i got a case dual-bladed slipjoint from my father when i was, oh, about 8. managed to cut a finger (not really badly) the first day i used it whittling, and he took it back, probably in the vain attempt to keep me from being a dummy. many years later (maybe about 15 or so), he gave me a case with the end snapped off of one of the blades, because it wasn't very useful to him anymore. i need to ask him whether it is the same one or not, and perhaps i will grind the snapped blade to something useful again. beautiful little knife. i was in awe of it when i first touched it, as i am in awe with every new knife i hold/use.
