A fast-cutting, 2 1/4" diameter sharpening stone with a friction-fit rubber clamshell case for secure grip. Made of durable ceramic abrasive, it has a coarse 180x side that removes nicks and leaves a toothed edge suitable for most large garden implements, and a fine 600x side for honing or maintaining an existing edge.
The stone is best used with water as a lubricant, but can also be used dry. Unaffected by freezing temperatures, even when wet. Its compact size makes it an ideal carry-along to the woodlot or campsite.
