| 摘要 |
A rotary mower blade sharpener device formed substantially of a resiliently deformable material and characterized as having abrasive properties and friction gripping properties on opposing surfaces thereof. The opposing surface having friction gripping properties is adapted, when laid upon the ground or other expansive surface, to retard rotation of the device when the blade to be sharpened is subject to momentary rotations in surface engagement with the opposing surface having abrasive properties. The relative rotation of the blade with respect to the surface of the device having abrasive properties effects sharpening of the blade.
