Abstract
Shovels and trowels are formed from metal and plastic for enhanced soil and sand penetration, and for cutting into roots. The shovels and trowels can each have one or more narrow tip teeth edges extending outward from the front end of the blade, the teeth edges each having embossed surface portions for strengthening the blade and disbursing stress during digging applications. The embossed portions can be indented. The embossed portions can be raised. A shovel version can also have foot brakes on both side of the handle above the rear end of the blade, to allow for a stable and safe foot placement.
Claims18
A shovel, comprising:
- a handle portion having an upper end and a lower end, and a longitudinal axis therebetween;
- a blade having an upper surface, and a lower surface, with a front end, and a rear end attached to the lower end of the handle portion;
- foot brakes extending upward from the rear end of the blade, the foot brakes having a flat horizontal surface edge allowing for a stable surface form foot of the user to contact during digging, wherein each of the foot brakes has a first bent flange extending substantially upward at an angle from the rear end of the blade, and a second bent flange extending rearward from a top of the first bent flange at an angle of approximately 135 degrees, the second bent flange having a flat horizontal top edge when the shovel is in a raised vertical orientation to allow for the stable surface for the user to push on during digging;
- one or more narrow tip teeth edges extending outward from the front end of the blade, each of the narrow tip teeth edges having a triangular shape with flat inwardly angled sides;
- and
- embossed surface portions formed in the one or more narrow teeth edges for strengthening the blade and disbursing stress when the shovel is used for digging applications, each of the embossed surface portions having a rounded rear end that runs from behind the front end of the blade to a narrow tip end located in each of the narrow tip teeth edges.
