发明名称 TRENCH SHOVEL
摘要 A trench shovel with a tempered steel blade having a width narrower than its length, and typically has a rounded or pointed front edge for penetrating into the earth, and a transition portion that has extending there from a tubular member for attachment of a handle of rectilinear cross section. The tubular member extends from the transition portion at an angle selected to provide a pre-selected function for the trench shovel. An angle of about 90 degrees or more allows the shovel to be forced with the toes or ball of the foot in the direction of the front edge, while an angle of about 120-150 degrees allows the shovel to be forced with the toes or ball of the foot in a manner similar of conventional shovels, typically against a pair of toe pegs secured to the rear portion of the tubular member or transition portion of the trench shovel.
