Whetstone results, without the whetstone
- The angle is locked for you
- Built-in magnets hold the blade at exactly 12 to 22 degrees while you roll. Freehand guessing is where home sharpening goes wrong, so it's removed entirely.
- Industrial diamond face
- The drum's diamond side rebuilds the edge; the fine side polishes it clean. Two passes, one tool, no water, no mess.
- Kind to good knives
- No motorized wheel chewing metal off your blade. The drum removes only what the edge actually needs.
- Beech, steel, and magnets
- A solid wood tool that earns its place on the counter instead of hiding in the junk drawer.

The tomato test doesn't lie. Paper-thin slices, zero pressure.
Four steps, about ninety seconds
1Snap the knife to the block
Magnets grab the blade and hold it steady.
2Pick your angle
12° for razor work, 22° for heavy duty.
3Roll along the edge
Back and forth, diamond face first.
4Flip and finish
A few passes on the fine face to polish.
Watch it work
One dull knife, start to finish
Setting the angle, the passes on the diamond face, the flip to the fine side, and the cucumber test at the end — narrated the whole way through.
1:17, sound on.

Questions, answered
Will it sharpen serrated knives?+
No. It's built for straight-edged blades: chef's knives, santokus, paring, utility, boning and carving knives. Serrated bread knives need a different tool, and we'd rather tell you that now.
Which angle should I use?+
15° is the sweet spot for most kitchen knives. Go 12° for delicate slicing blades, 17° to 22° for cleavers, outdoor knives, and anything that takes abuse.
Does it fit long chef's knives?+
Yes. The block holds the blade while the drum rolls along it, so length doesn't matter. Any straight blade the magnets can hold, it can sharpen.
How long does the diamond face last?+
Years of home use. Diamond abrasive doesn't wear like a whetstone, and there are no pads or cartridges to replace.
How long is shipping?+
7 to 14 business days to the US, Canada, UK, Australia, New Zealand and Ireland, tracked the whole way. Shipping direct from the supplier's warehouse is what keeps the price under half of the big-name rolling sharpeners.
What if I don't like it?+
Email us within 30 days of delivery and we'll refund you in full. No reason needed.
