Abstract
An electric oyster knife has a case (1), a blade holder (12) with a blade (13) slidably longitudinally between outer and inner positions with respect to the case, an electromagnet (2) mounted in the case for oscillating the blade holder between its two positions. An armature (7) is pivotally mounted in the case. The armature has a cam surface (11) for driving the blade holder toward its outer position, in a first position of the armature, and for allowing the blade holder to move to its inner position, in a second position of the armature.
