A meat tenderizer with disposable face plates requires that a fresh face plate be chosen for each use to prevent cross contamination from one use of the tenderizer to the next. The table or tables of the tenderizer head are flat and accept the face plates which may have a flat tenderizing surface or any of several textured tenderizing surfaces. The face plates are intended for a single use. Once used a face plate is discarded. The user selects the appropriate face plate for the task at hand, attaches it to the tenderizer and removes and discards it after use. Since a clean unused face plate is selected for each use, the tenderizer does not have to be washed between uses thereby saving time for the chef and providing a sanitary tenderizing surface for contact with the meat.

A hand-held epilating device capable of increasing plucking efficiency. The epilating device has a housing to be grasped by a hand of a user, and a plucking cylinder carrying at least one set of pinching elements for catching and pinching body hairs therebetween. The plucking cylinder has a longitudinal axis and is driven to rotate about the longitudinal axis to pluck the body hairs from the user's skin. The plucking cylinder is supported to the housing so as to effect a periodical movement relative to the housing within a plane parallel to the longitudinal axis. Thus, the area of the skin covered by the plucking cylinder can have increased chances of being in contact with the pinching elements as the pinching elements move periodically relative to the skin together with the plucking cylinder, thereby improving the plucking efficiency.
