This compact professional electric 2-Stage knife sharpener sharpens both straight edge and serrated knives to better than factory edges, in just minutes. 2-Stage sharpening provides “Gothic Arch” shaped edges which are stronger and longer lasting than hollow ground or conventional “V” edges. Stage 1 uses 100% fine diamond abrasives to create the first bevel and Stage 2 ultra hones the edge using advanced micron size 100% diamond abrasives to complete the second bevel. The precisely formed conical diamond abrasive disks gently apply optimal sharpening pressure, guaranteed to never detemper the edge. Highly precise knife guides automatically position and stabilize the knife as you sharpen for fast, foolproof results. It’s ideal for sharpening all types of knives, including kitchen, household, sporting and pocket knives. One year limited warranty. UL or ETL and Canadian Approval. Assembled in the U.S.A.
