Is a defendant liable for possession of a razor blade?

Defendant was convicted of section 4502 which prohibits possession, among other things, of sharp instruments. Sections 4502 and 4575 create strict liability for possession of proscribed weapons and devices. A plain razor blade's potential for use as a deadly weapon does not depend on an intended violent use. In determining the potential of a proscribed item to cause great bodily injury or death, we do not consider the percentage chance of great bodily injury or death. (See People v. Savedra (1993) 15 Cal.App.4th 738, 745.)
