My chef knife used to crush tomatoes instead of slicing them. Four passes on the EdgeRoll diamond disc and it cuts through skin clean. I sharpen it once a month while the coffee brews now.

The magnet holds your knife at the exact preset angle so every pass lands the same, even on your first try.
The 400-grit diamond restores nicked or rolled edges. The 1000-grit ceramic polishes them to a working finish. Both discs are replaceable.

N42-grade magnets hold a 10-inch chef knife from heel to tip with no mid-roll slippage — the failure mode that makes cheap rollers dangerous.
Walnut and beech housing with aluminum reinforcement takes the pressure of every roll without flexing or binding.
Based On Real and Honest Experiences
My chef knife used to crush tomatoes instead of slicing them. Four passes on the EdgeRoll diamond disc and it cuts through skin clean. I sharpen it once a month while the coffee brews now.
Bought EdgeRoll for my Japanese sushi blade, a 12-degree grind most rolling sharpeners butcher. The preset hit the angle exactly and the fish slices like the day I unboxed it.
Expected a $30 Amazon knockoff at this price. Instead the magnet held my full chef knife with zero slip, and EdgeRoll got it sharper in three minutes than a year of whetstone attempts ever did.
