Overview

The Corona Sharpening Tool (AC 8300) is a small portable accessory designed for sharpening pruners, loppers, shears and more. It was found locally in-store at Lowes for $8.98.

Compared to sharpening stones, it is expensive. However, they were not designed for sharpening garden tools. The Corona Sharpening Tool (AC 8300), on the other hand, features a small sharpening stone on the end of a metal stick. As a result, the garden tool can be held stationary, while the sharpening tool is scraped along the blades edge. For curved by-pass blades, this is far more efficient and effective at reaching the intersecting inner edges.

A black plastic cap is also included for covering the sharpening stone. The cap is flexible and will prevent the stone from inadvertently scratching things.

Measured dimensions are 5” x ⅝” x ¼” with the plastic cap on. It’s small, compact, and easily pocketable.

Test were performed on some dull loppers and pruners. With 5 strokes on the cutting edge and 1 stroke on the flat side, both tool blades were very sharp to the touch. Don’t touch too hard or you’ll cut yourself!

Overall, the Corona Sharpening Tool (AC 8300) is highly recommended. It’s simple, compact, and effective at sharpening pruning tools. As a result, the price of $8.98 seems like a bargain.
