This is a pretty handy little cutter, given how small and thin it is. Here's the details from the On The Fly site.

XIKAR's Xi series of cutters are world renowned. So when they introduced a cutter without the iconic "teardrop" shape, you can rest assured the Ultra has passed their strict tests for sharpness, quality & style. As thin as a few credit cards, (only 3.5mm thin!) the Ultra will fit any occasion. As useful as any Xi cutter, you'll never forget it rests your pocket or wallet.

It comes in three colors, gold, silver and gunmetal, but it's a little on the pricey side at $50.
