For simple, fast, razor sharp pro edges on our Söliditi™ C5, and all Japanese and Western knives — single-sided chisel edges and regular two-sided edges.
Read real reviews from our Early Adopters HERE!
The InversionEdge™ Sharpening System includes:
- 1 x nöni™ tray (platform)
- 1 x Love Handle
- 4 x Rubber Magnets
- Ultrafine grit Naniwa stone — 3000/8000 (only if ordered)
- Coarse Naniwa stone — 220/1000
N.B. When it comes to grit, the higher the number, the finer the grit.
InversionEdge™ will create a far superior edge to your original factory edge, no matter which brand. InversionEdge™ not only allows you to create a symmetrical cutting edge, but it also allows you to easily create the famed 'double bevel' on each side of the blade — almost impossible by hand.
Symmetrical bevels — Maintain standard symmetrical bevels (edges) — same bevels each side.
Asymmetrical bevels — Convert your old blade to asymmetrical for higher performance cutting. This bevel is highly recommended if you want 'next level' pro cutting.
Fine grit stone (3000/8000): If your blade is in very good, thin, sharp condition or you've used InversionEdge on this blade before.
Coarse grit stone (220/1000): If this is the first time for this particular blade on InversionEdge, and your blade is quite dull and worn.
Push the Love Handle spring clip onto one end of your combination stone, with the higher loop side on the fine side of the combination stone.
Fine angled platform — choose for almost all knives — Western, Japanese and Söliditi Usudeba
Wide angled platform — choose only for blades that need toughest symmetrical edges (sporting knives, workshop knives, big hacking knives)
- Stick the magnet to one end of the chosen edge, in line with the tray top edge.
- Mount knife securely on to the magnet (you can add an additional magnet on top for extra strength).
- Ensure the cutting edge of the knife protrudes above the magnet all along its length.
For thin, sharp blades:
- Wet the stone (no need to soak our Naniwa stones).
- Start with the fine grit side of stone to refine your primary bevel — Love Handle loop should be facing down. The Love Handle will automatically set the correct angle. Use mostly lengthwise motion with a little crosswise, to sharpen the blade from tip to heel.
- When sharp, flip the blade over and stick it on the other end of the same platform. Repeat until bevels are approximately the same size on both sides.
For thick, dull blades: Start with the coarse grit stone (220 on our Naniwa stone) to quickly reconstruct the edge, then follow the fine grit process above.
