A ditch shovel is disclosed with a total weight between 9 and 15 pounds. The weight of the shovel allows the user to develop significant downward momentum to penetrate more deeply into the ground and dislodge more compacted earth.
Claims2
A handle for a shovel, the shovel being adapted to dig trenches and holes, comprising:
- (A) a heavy gauge pipe weighing substantially between 7 and 11 pounds and being of a length wherein the total length of the shovel is substantially between 77 and 89 inches for a user to hold the shovel and for providing mass, whereby said pipe is strong enough to withstand large stresses and is massive enough to develop a large downward momentum when thrust downward,
- (B) a flared end on said pipe for preventing a users hands from slipping off of said pipe,
- (C) insulating material covering at least part of said pipe for insulating said pipe, and
- (D) attachment means for attaching said pipe to a shovel blade,
- whereby the shovel may be comfortably used to dig deep trenches and holes by a user who stands on the surface of the ground.

A shovel for probing for buried objects in a trench or hole, the trench or hole having a bottom below the surface of the ground, the shovel comprising:
- (A) a heavy gauge pipe handle weighing substantially between 7 and 11 pounds for a user to hold the shovel and for providing mass, whereby said handle is strong enough to withstand large stresses and is massive enough to develop a large downward momentum when thrust downward,
- (B) a narrow shovel blade attached to said handle for penetrating earth, whereby said blade deeply penetrates earth when thrust into the ground,
- (C) the total length of the shovel being substantially between 77 and 89 inches, whereby a user may thrust the shovel into the bottom of a trench or hole while standing on the surface of the ground, the shovel being long enough for the user to manipulate the shovel when the shovel is imbedded in the bottom of the trench or hole,
- (D) insulating material covering at least part of said handle for insulating said handle and providing a more comfortable grip, and
- (E) a flared end on said handle for preventing a users hand from slipping off of said handle.
