DMT Diafold Double Sided Diamond Folding Sharpener

The DiaFold Double Sided Diamond Sharpener is one of DMT’s most popular products of all time. Each dual-sided sharpener has two color coded diamond abrasive grits, both featuring DMT’s classic polka-dot interrupted sharpening surface. Held comfortably by the fold-out handle, the DiaFold is a convenient way to sharpen axes, knives, shears, or draw-knives.

Like all DMT products, the DiaFold can be used dry, so there’s no clean up, and you don’t need a water source nearby to sharpen. The folding handle becomes a protective cover that protects the abrasive from the contents of your tool box or pocket.

Four grit pairs provide a range of sharpening options for different applications. The Fine/Coarse sharpener is a good one stone option for tools like axes that don’t need a razor edge. A pair of Extra Coarse/Coarse and Fine/Extra-Fine sharpeners gives a full range of grits for edge repair followed by honing. The Extra-Fine/Extra Extra-Fine sharpener puts the finishing touch on edges that just need a little touch up.

Dimensions: Abrasive surface measures 4 3/8″ by 7/8″ by 1/4″ with a 5″ long handle. Folded dimensions are 5″ by 1 1/4″ by 7/16″
