A device comprising:
- a tool;
- a shaft;
- and
- a D-shaped pivot hoop extending from the shaft, wherein the pivot hoop comprises a first flat portion, a second flat portion, and wherein the first flat portion and second flat portion transition to an arc portion, and wherein the first flat portion and second flat portion have a first thickness, and the arc portion has a second thickness, wherein the second thickness is less than the first thickness;
- and wherein the arc extends approximately 180 degrees between the first flat portion and the second flat portion.

A device comprising:
- a tool;
- a shaft;
- and
- a pivot hoop extending from the device at two interface points, wherein the pivot hoop comprises a flat portion at the first interface point closest to the tool, wherein an arc portion is formed between said flat portion and the second interface point;
- wherein the first flat portion has a first thickness, and the arc portion has a second thickness, wherein the second thickness is less than the first thickness, and
- wherein the first flat portion of the pivot hoop that contact ground during use spreads force load onto the arc portion and causing a rolling in one direction, thereby increasing stability of the device during use.
