Aprille Mammone v. Vector Marketing Corporation; Jordan Anderson, No. CV 1003399 (Marin County Super. Ct. filed June 29, 2010).

Complaint for negligence. The defendants were engaged in a sales presentation of kitchen and sporting knives when they negligently allowed the plaintiff to handle a knife without proper supervision; the plaintiff was injured when the knife slid out of its case.

Actually, I guess it's a good thing the plaintiff found out knives are sharp before she got them home, where I assume she was planning to use them without any supervision at all.  What a bloodbath that could have been.
