Chef’s Choice brings new technology to knife sharpening introducing Rechargeable DC Electric Knife Sharpeners. An integrated lithium battery allows for compact, cordless sharpening and is easily rechargeable by USB-C. Designed with a smaller footprint than other electric sharpeners, it still has all the sharpening power and precision Chef’s Choice is known for, now with the portability to take anywhere. With a direct current motor, the Three-Stage Rechargeable DC Electric Knife Sharpener is more energy efficient due to lower power consumption. Compact and powerful, this professional sharpener uses advanced technology to sharpen both straight edge and serrated knives. Three-Stage sharpening provides double-bevel edges, which are stronger and longer lasting than hollow ground or conventional “V” edges. Stage 1 uses 100-percent, fine diamond abrasives to create the first bevel. Stage 2 ultra-hones the edge using advanced micron-size diamond abrasives to complete the second bevel. In Stage 3, patented stropping disks create an unparalleled polished finish. The precisely formed, conical, diamond abrasive disks gently apply optimal sharpening pressure, guaranteed to never soften the blade. Highly-precise knife guides automatically position and stabilize the knife as you sharpen for fast, foolproof results. Sharpen with ease as this rechargeable electric knife sharpener is covered by Chef’s Choice one-year limited warranty.
