Abstract
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 nuts and bolts for fastening the detachable tip to the spade head in which 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, and 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.
