Abstract
Disclosed is a blade for cutting and scrapping that is receivable by a holding device. A keeper is joined to a base plate of the holding device by means of a pair of screws. The blade is constructed with a pair of slots of different lengths extending inwardly from opposite ends of the blade and running generally parallel to the cutting edge of the blade. The blade may be inserted between the keeper and base plate with one screw being received by the longer of the two slots. The blade may then be positioned between the keeper and base plate with the shorter slot aligned with the other screw. The blade may then be moved forward so that the shorter slot receives the second screw while the longer slot still retains the first screw. Tightening the screws then secures the blade in cutting position between the keeper and the base plate.
