DIAMOND SHARPENING DISC
Strips back the edge. Fast.
Diamond is the hardest natural material on Earth — and that’s exactly why it works.
This disc removes the first layer of your knife’s edge fast, getting it back into proper shape with zero fuss. No water. No soaking. Just straight to the point.
FINE HONING DISC
Refines the edge. Finishes the job.
Once the diamond disc has done the heavy lifting, this disc steps in to smooth things out. It cleans up any burrs or leftover roughness — so your edge isn’t just sharp, it’s clean and precise.
