Our 3-way sharpener is precise, compact and easily carried and will allow you to maintain the same 18-degree angle our craftsmen place on most knives here in our factory. This sharpener uses a set of ultra-hard carbide inserts that re-cuts the same factory set angle. Each sharpener includes a fold-out flat double-coated diamond steel to remove the blade’s wire edge, any burrs or nicks, and a diamond coated rod for sharpening gut hooks and serrations.
