Materials
- Example
The materials used in the production of the trimmer must be readily available, easily fabricated, and of the required properties. These include resistance to stones and other garden waste being flung onto them, and to being dropped 5 feet (if the trimmer falls off a peg on the shed wall). The materials must also resist the rapid corrosion induced by wet grass, and corrosive agents such as sap.
If electrical components are required, they must have the correct insulative or conductive properties.
