Bladeless

"The only thing salvaged from the wreckage was a knife that belonged to the late captain. The knife was remarkable, for it had all sorts of tools attached to it and could do just about everything. It could open a bottle of wine, tell you which direction was north, and crack the shells of recalcitrant oysters. Its one drawback was that you couldn't cut anything with it, since it lacked a blade, the inventor having run out of room, but that was a minor inconvenience compared to the fact that you could use it to trim your nose hairs."
