OK, this is pretty cool. The Pickmaster Plectrum Cutter seems like a must-have accessory for any guitarist, in that this punch device lets you create unlimited custom guitar picks from any hard plastic card – such as a used gift card, or expired credit card – for an initial investment of just $39! The downside of this being such an in-demand item, of course, is that is is currently out of stock at Amazon UK, but I suppose you could keep checking back for a restock.

Thanks to Karl Brandt for the Tip!
