Give Your Knife Sharpener Its Bite Back
Does your sharpener feel slower than it used to? Over time the discs wear smooth and start to polish the blade instead of cutting it. This kit gives you two fresh diamond discs, 400 grit and 1000 grit, so your sharpener works like new again.


Why replace your discs?
Worn discs polish instead of sharpen
Every sharpening session wears the disc surface down a little. After a while the abrasive becomes smooth, and instead of cutting a fresh edge it only rubs and polishes the steel.
New diamond discs restore the bite and bring your sharpener back to peak performance, so you get much more life out of the tool you already own.

400 grit
The foundation
The 400 grit diamond disc removes fatigued steel, reshapes the edge and restores a clean cutting profile.
It is designed to do the heavy lifting: fast, controlled and efficient.

1000 grit
The refinement
Once the edge is reset, the 1000 grit disc takes over. It smooths and refines the bevel, reduces scratch marks and dials in the sharpness.
The result is a cleaner edge that cuts effortlessly and stays sharp longer.

Made with genuine diamond
Two essential grits for all knives
The discs are coated with genuine diamond particles that bite into the steel of all your kitchen knives.
They work precisely and remove only minimal material from the blade, which helps your knives last longer.
- 400 grit: resets and reshapes the edge.
- 1000 grit: refines and sharpens.
- Genuine diamond abrasive surface.
- Removes minimal material from your knives.
