Abstract

The tool for the rapid opening of shells of japanese oysters, is some three times faster in operation than conventional hand tools; and is for attachment to a small hand held pneumatic hammer. The tool has a hexagonal haft (1) to prevent rotation of the blade and the blade has a demi-rounded tip. The tool is preferably fabricated from forged steel. This usage represents a unique application of a pneumatic drill and a suitable drill has a working pressure of 0 to 6 kg/cm2 and a proportional vibration of 0 to 3600 blow per minute. The tool travel is 15 mm maximum, and the length of the blade is 10 cm, with a flattened tip (3).
