I'd love a Spyderco utility knife! My knives get abused too often at work for me to be able to buy a new one all the time, or spend all the hours fixing edge every time it gets beat to heck. The utility blades are also able to cut through some things like hard plastic that a real blade could never be thin enough to handle. I've carried a sheffield/husky/cobalt at work for a long time, but they are heavy, cheaply made, poorly locking, and don't hold the blade very well. I'd love a real one! Spyder blades would be awesome too. Another cool idea, although probably not possible, would be to make a dyad sort of knife with a "real" blade on it too.
