Always wear safety goggles before operating the sharpener.
6.1 Sharpening Knives, Scissors, Chisels, and Planers
- Identify the appropriate sharpening slot for knives/scissors or chisels/planers. These slots are typically located on the side of the unit and feature an adjustable angle guide.
- Adjust the sharpening angle using the knob or lever provided, typically ranging from 15° to 50°, to match the existing bevel of your tool. The width can be adjusted from 6mm to 51mm.
- Turn the sharpener ON using the power switch.
- Carefully insert the blade into the chosen slot, ensuring it rests against the grinding wheel at the desired angle.
- Apply light, consistent pressure and draw the blade smoothly across the grinding wheel. Repeat this motion several times, alternating sides if sharpening a double-bevel blade, until the desired sharpness is achieved.
- For chisels and planers, ensure the straight edge is maintained during sharpening.
- Turn the sharpener OFF after use.

- Turn the sharpener ON.
- Carefully insert the drill bit placer with the drill bit into the designated slot.
- Rotate the drill bit gently as instructed by the markings on the unit or the placer, ensuring even sharpening of both cutting edges.
- Continue until the drill bit is sharp and the original point angle (approximately 130°) is restored.
- Turn the sharpener OFF after use.
