摘要:
A multi-purpose spade includes a spade head having a “V”-shaped cutout a detachable tip constructed, to substantially conform to the “V”-shaped cutout of the spade head and a fastening means for fastening the detachable tip to the spade head. The spade head includes first and second inner edges, and cutting edges or blades are formed on the first and second inner edges. However, such cutting edges or blades are not formed on a region adjacent to the pointed end of the “V”-shaped cutout. The first and second inner edges form an angle of about 30˜40 degrees, and more preferably about 30 degrees. The first and second edge portions have longitudinal slots respectively to receive the first and second inner edges. The fastening means may be nuts and bolts such that bolts pass through holes, formed, on the edge portions and inner edges, being fastened to nuts.
