  • Patent number: 5581889
    Abstract: A versatile hand-held garden tool for cultivating, digging, weeding, pruning and trimming has a blade, a handle and a neck angling upwards from the blade that connects the blade to the handle. The blade has a body portion that is preferably 5"-7" long and a tip portion angling upwards from the body portion that is preferably about 1 inch long. The body portion has two edges, one edge is serrated and the other edge is beveled. The tip portion has a beveled edge. It is preferred that the handle have a V-shaped cross section to facilitate the mounting of a grip. The garden tool can be made by cutting a blank from a web of cold rolled steel having a thickness of about 0.075 inches, coining the beveled edges into the blank, and forming the tool by bending the blank. It is then preferred to heat treat and plate the cold rolled steel.
