These have been around for a while, in quite a few forms. The other day my chef showed me the catalog of the goods from our 'corporate approved vendors' that are ridiculously overpriced and I pointed out a stainless steel 'restaurant grade' slapchop that was only 9.
K-Tel, known mostly for their music compilations, marketed this protoslapchop in a display of market aggression towards Ronco, Americas premier vendor of useless shit. Ron Popeil responded to the challenge by crazy gluing his head to a girder and throwing in a Pocket Fisherman as a free gift.
