An updated look at the notion of blood pacts, this pen uses the userâs own blood as ink. With a simple, piercing tap of the forefinger, the needle tip fills with blood and dispenses through the nib onto a page. Signatures applied using the blood pen are doubly authentic, as the ink contains the genetic identity of the signatory.

The ultimate use of the blood pen is in signing a peace treaty to end war. Using the blood pen in this instance ceremoniously ends the conflict with one last act of bloodshed.

Gavin Ivester: "It's totally cool...The Blood Pen's power is its simplicity. It's an instantly graspable concept-what it does, how it works, and why you would need it. Ideas this pure only come along once in a long while."

Anne Ellegood: "I love it! This would be best for historical signings...It's simple and it's smart."

Bruce Nussbaum: "The visceral power of a 'blood pact' signed in a person's own blood may just be the way to reestablish trust and morality in a world awash in deceit, lies and crumbling values. Blood binds."
