The Tim Holtz hardware findings die by Sizzix is the kind of die that you'll keep on thinking of multiple ways to use it.  You can use it to cut prints from a variety of materials, or use it to cut grungeboard to finish in any way you want.  The 3 elements in the die are spaced just right, so that you can isolate the piece(s) you want to cut.  In addition, Sizzix dies are very well constructed, and they last for a long time.  I highly recommend this die.
