            adhere to the following rules: * The location numbering **SHOULD**
            start at the furthest {{block(CuttingItem)}} and work it’s way back
            to the {{block(CuttingItem)}} closest to the gauge line. * Flutes
            **SHOULD** be identified as such using the word `FLUTE`:. For
            example: `FLUTE`: 1, `INSERT`: 2 - would indicate the first flute
            and the second furthest insert from the end of the tool on that
            flute. * Other designations such as `CARTRIDGE` **MAY** be included,
            but should be identified using upper case and followed by a colon
            (:).
