Abstract
A tool for cutting through roots in the soil includes an elongate bar formed of solid steel with an enlarged knob on a top end and a weighted cutting head on a bottom end. The cutting head is formed of solid tempered steel and is in the configuration of an axe head with a sharpened arcuate cutting edge on the lowermost distal end. A longitudinal axis of the bar extends through a center of the cutting edge. In a preferred embodiment, the entire tool is made as one piece forged steel.
Claims4
A root cutting tool comprising:
- an elongate solid steel bar having a first end and a second end, and a longitudinal axis extending from the first end to the second end, and a diameter defining a transverse dimension of the bar:
- a knob on the first end of the bar and the knob having a transverse dimension that is greater than the transverse dimension of the bar;
- a cutting head formed of solid tempered steel at the second end of the bar, and the cutting head including a continuous arcuate cutting edge at a lowermost distal end of the tool, and a center of the continuous arcuate cutting edge positioned in axial alignment with the longitudinal axis of the bar, and the continuous arcuate cutting edge extending beyond the transverse dimension of the bar;
- the cutting head further including opposite lower side faces adjacent to the continuous arcuate cutting edge, that is convex and the opposite lower side faces being angled relative to one another at an acute angle;
- the cutting head further including opposite upper side faces extending from the opposite lower side faces to a top end of the cutting head, and the cutting head having a maximum transverse width measured between the opposite upper side faces that is greater than the transverse dimension of the bar;
- and
- the cutting head further including rounded outboard corners at the top end, wherein the weight of the cutting head ranges between 4-8 pounds.
