Precision speed control (0–3000 RPM) with forward/reverse switch Adjust speed to match the task: slow for fine edges, fast for rapid material removal. Forward/reverse lets you control burr direction and finish while reducing heat buildup on blades and delicate edges. Upgraded ‑torque copper motor — 30% more power Stronger, more consistent torque than standard motors reduces stalling and jamming. Delivers smooth, professionalgrade sharpening with less strain on the motor and the workpiece. Three grinding wheels for complete edge work 320 grit (coarse) for shaping and repairing chips 800 grit (medium) for refining the bevel 2000 grit (fine) for polishing and achieving a nearmirror finish Swap wheels quickly to move from rough grinding to final polishing without changing tools. Stable, safe operation on table or in hand Solid aluminum alloy tray provides a rigid platform; four silicone pads minimize wobble and prevent slipping during use. Use hands on a tabletop for precise positioning or hold securely for controlled handheld sharpening. Designed for knives, chisels and delicate tools Compatible with a range of edged tools where controlled speed and heat management matter: kitchen knives, woodworking chisels, carving and precision blades. Adjustable speed and the reverse option help protect temper and edge geometry. How this solves common sharpening problems Prevents overheating: low RPM settings and speed control reduce heat transfer that can damage blade temper. Prevents jamming and inconsistent results: ‑torque motor keeps wheels turning under load for steady material removal. Improves stability and safety: aluminum tray plus silicone pads reduce vibration and movement for more accurate, repeatable edges. Performance and materials at a glance Motor: upgraded ‑torque copper motor (30% more power vs. standard) Speed: adjustable 0–3000 RPM Direction: forward/reverse switch Wheels: 320, 800, 2000 grit Base: aluminum alloy tray with four silicone anti‑slip pads Practical use scenarios Kitchen maintenance: Reprofile and polish chef's knives and utility blades quickly at the correct speed to avoid overheating and maintain edge life. Woodworking : Restore and refine chisels and plane irons from rough shaping to a polished micro‑bevel using the coarsetofine wheel sequence. Hobby and precision work: Keep carving tools, small blades and precision instruments sharp and consistent without risking edge damage from excessive heat or motor stalls. What to expect in everyday use Easy speed and direction control for predictable results Smooth, continuous torque for consistent grinding Rapid wheel changes to progress from rough to fine finishes Stable tabletop mounting or secure handheld use for flexible workflows This tool combines adjustable speed, enhanced motor power, three dedicated grits, and a stable aluminum tray with silicone pads to deliver dependable sharpening performance for knives, chisels and other delicate cutting tools.
