Many die sets come tabbed and you need die snips to cut them apart.  The Kat Scrappiness die snips (also known as side snips) are flat on the back edge, allowing you to get right up against the edge of the die to cut as close as possible.  

*Safety Disclaimer*

This is a very sharp tool and should not be used by children or left near them.  You should always wear protective eye wear when using these or any die snips to avoid injury.
