Abstract
A heavy duty, earth-working implement including an elongated handle having a wedge-shaped head mounted thereto which extends upwardly from a cutting blade along a continuously curved back surface which functions as a fulcrum to assist in prying rocks and other earth buried debris, which fulcrum terminates in a ledge which is aligned with the cutting block of the head so that a driving tool may be used to strike the ledge to thereby facilitate penetration of the cutting blade of the tool.
Claims5
A handheld earth working implement for use in penetrating soil and cutting subsurface objects and for prying objects, the implement comprising,
- an elongated handle having upper and lower end portions,
- an integrally formed and solid working head mounted to said lower end portion of said handle, said working head including a lower cutting blade and a front face and a rear face, said rear face extending from said cutting blade upwardly toward an inwardly extending ledge and being generally continuously arcuate and convexly configured along its length so as to provide a continuous fulcrum beginning at said cutting blade about which the implement may be pivoted, said ledge extending generally perpendicularly with respect to said cutting blade and extending inwardly and toward said lower portion of said handle and said ledge defining a flat surface adapted to be impacted by a separate driving tool, said implement head including opposite sides which taper inwardly relative to one another toward said cutting blade from said adjacent said ledge, and said sides terminating at said rear surface and said front surface of said working head.
