Aaron's feeding razor is a vampiric artifact.
A Malkavian who despised having to touch people created this magic razor blade in the early 17th century with which to draw blood. He preferred not to drink directly from vessels for fear of having them dirty him. The razor has been passed along for many years, and supposedly has the power to choose victims with pure virgin blood (Aaron’s favorite). The blade is also believed to have the power to cause aggravated wounds.
