Abstract

A clamp for safely opening oysters and the other molluscs. It works as a pincer to trap an oyster to be pryed open. The clamp consists of two half-shells, hinged together at their rear ends to a closed position forming an oyster receiving enclosure opened at the front to expose the oyster. The bottom half shell is larger than the top half shell so as to receive the latter and thus vary the size of the enclosure to trap oysters of different sizes. The front edge position of the two half shells form outward ribs serving as a hand shield for the users hand, which presses onto the half shells to trap an oyster and hold it firmly while the other hand uses an oyster knife to pry it open.
