The blade has a special tongue connection means on the supported end which snuggley fits into the end of the shaft and is adherred thereto by an adhesive such as an epoxy resin. The cap is cup-shaped and is preferably molded from a hard plastic and is adherred to the opposite end of the shaft from that supporting the blade to cover the end threreof. The cap could also be made from an elastomeric material to be frictionally retained in position over the shaft end. The use of the adhesive material makes certain that the cap will remain in place. Should the blade be damaged, chipped, broken or otherwise unuseable, it is sawed or otherwise separated from the end of the shaft and another blade has its tongue inserted into and adherred to the opposite end of the shaft after the cap was removed or had the top…
