Smith's Compact Electric Knife Sharpener Diamond 1 pc.

The crossed ceramic rods put the final finished edge on your blade. Crossed ceramic rods create a fixed sharpening angle that lightly hones both sides of your blade at the same time; thus, putting a polished, razor-sharp cutting edge on your knife. Also, the crossed ceramic rods are excellent for giving already sharp knives a a quick touch-up before use. Just a few, quick pulls through the sharpening slot is all it takes. Smith's recommends always using the ceramic rods for final edge honing after you sharpen using the synthetic wheels. Again, just a few pulls through the sharpening slot is all it takes. * *
