This Ken Onion Edition MK.2 knife and tool sharpening accessory expands your sharpening system, giving you greater control over every knife you sharpen when sharpening horizontally on a workbench. Larger 1" x 18" blades, a fully adjustable cutting angle from 10° to 35°, and three convex edge profile settings allow you to fully control the sharpening process to achieve the desired edge on your knives. We designed this ability into this accessory so you can achieve professional results quickly and easily. Two reference plates make it easy to maintain the cutting angle while providing a contactless sharpening experience, so you can trust your most coveted knives. Designed in collaboration with knife-making legend Ken Onion.
