The CardSharp, Cutting Edge Design (literally) and Beautiful Packaging.
The CardSharp 2 from Iain Sinclair is a cool little functional utility knife that is beautifully incorporated into its package design.
Just three ingenious folding operations metamorphosize the card into an elegant pocket utility tool.
Measuring the size of a credit card, the lightweight, ultra thin Card Sharp 2 has stainless steel surgical blade that measures just under 3" long and is both waterproof and rust-proof.
Updated features (from the original Card Sharp) include a stiffer, non-slip armor rubber coated body and unique safety lock (cannot accidentally open when in a pocket or drawer and is child proof).
For only £15 GBP ($25 USD), the Card Sharp2 makes a great and handy gift or stocking stuffer, especially with the option to customize the blade (as shown below):
