Professional-grade refinement for exceptional sharpness. This Horl 3 Premium refining set takes your edge beyond standard sharpening, delivering finer results and greater sharpness through progressive polishing. Based on the Horl standard sharpening system, these premium refinement tools create a smoother cutting edge with lower resistance when gliding through ingredients. Set includes: Fine whetstone for initial refinement Extra-fine whetstone for optimal results Horl leather for professional finishing The fine grits of the two whetstones ensure an even smoother knife edge, used dry on a burr-free cutting edge.
