Installation / Usage Tips
Follow these steps for safe, effective sharpening:
- Choose the angle: 15° for precision/slicer blades, 20° for durable, all-purpose blades.
- Start with the coarse side (diamond 400 grit) to remove nicks or reshape the edge; make even passes across the blade.
- Switch to the fine grind (supplier-listed 1000#) then finish with the ceramic honing disc (3000 grit) for a polished, razor edge.
- Use light, consistent pressure — let the abrasives do the work. Several passes (not heavy force) produce the best result.
- Secure the blade with the magnetic guide and keep fingers clear of the edge while sharpening.
- After sharpening, wipe the blade clean and test cutting on soft food; repeat light honing passes as needed.
