That pick punch sounds like a great idea, if you could just find some way to make sure you always have it with you in any situation where you might need a pick.

You could buy several and keep one in each instrument case. Or maybe you could wear one as a pendant with your St Christopher medal. You should probably keep some sandpaper wrapped around it to smooth the edges of the picks and to keep the punch from bruising your chest.

Or, for the same price, you could buy 150 picks with the edges already beveled, and you could keep them in a little string bag on your pendant. That would probably weigh a little less and might feel more comfortable.

But either one would be hard to lose, which is really the point of this thread.
