Turn on the switch and hold the sharpener steady with your left hand. Choose the gear that matches your tool: I = medium/low speed, II = high speed. 2. Select coarse then fine grinding, or use fine grinding directly for maintenance. 3. Hold the blade or tool with your right hand, place the end in the polishing position, and pull it back toward the tip in an even motion. Practical uses and applications Daily kitchen use: quickly restore chef, slicing, or paring knives to peak sharpness before meal prep. Touch-ups while traveling: cordless operation and compact storage make it suitable for sharpening while camping, at a vacation rental, or in small kitchens. Workshop or multi-tool maintenance: use the two-stage system for a range of cutting tools that require coarse reshaping and fine polishing. Performance and compatibility notes Designed for routine sharpening of kitchen knives and similar cutting tools; use the coarse stage for dull or damaged edges, then finish with the fine stage for a polished edge. Two speed settings (I and II) allow control for different tools and sharpening needs. Charging is completed when the indicator light is fully lit; the hidden charging compartment keeps the cable stored and the unit compact. Usage tips for best results Keep the sharpener steady with one hand and guide the blade evenly with the other to maintain a consistent edge. For heavily dulled blades start with coarse grinding, then finish with fine grinding for a smooth, sharp edge.
