Why your knives are dull
A dull knife is the most dangerous thing in your kitchen — it slips, it crushes tomatoes instead of slicing them, and it turns ten minutes of prep into thirty. Pull-through sharpeners chew metal off your blade. Whetstones take practice most people never get around to. Electric sharpeners cost more than the knife.
How it works
- Stick. Lay your knife flat and let the magnetic base grab it at a fixed 15° or 20°.
- Roll. Run the diamond side along the edge, five to ten passes per side.
- Finish. Flip to the fine side, a few light passes, and slice paper to check.
Why the angle matters
Every sharpening method comes down to one thing: holding the same angle on every pass. Your hands can't. A magnet can. That is the whole trick — the same one behind the $120–$160 rolling sharpeners, without the price tag.
