Two Rolling Sharpeners: One to Keep, One to Give
Blunt knives, gone in two kitchens. This set has two rolling sharpeners, each with its own magnetic angle block, so you can keep one at home and give the other to someone who cooks: a parent, a brother or sister, or a friend who has been sawing at tomatoes for years.

The usual problem
Why most kitchen knives stay blunt

What you get
Two complete sharpeners
Each sharpener comes with its own magnetic angle block, so both kitchens get the full kit. It is super easy to set up and use, which makes it a thoughtful present for mum, dad, a brother or sister.
- 2 rolling sharpeners: diamond-coated disc on one end, ceramic disc on the other.
- 2 magnetic angle blocks: 15° and 20°.
How it works
Roll your way to sharp knives
1. Attach the knife to the magnetic block
Place the blade against the angle block on the side you want: 15° or 20°. The magnet holds it in place.
2. Roll the diamond disc along the edge
Roll the sharpener back and forth along the blade with light pressure. The angle is already built in, so there is no guesswork.
3. Polish with the ceramic side
Turn the roller around and use the ceramic disc to smooth the edge. Then enjoy chopping, dicing and slicing again.

Just roll
The perfect angle is already built in
Because the knife is held by the block, you never have to hold an angle yourself. You simply roll the sharpener along the blade.

Two discs in one
Sharpen first, then polish
The diamond-coated disc does the sharpening and brings back a sharp edge. The ceramic disc on the other end polishes it smooth.
The sharpener is built to last: the body stays, and only the sharpening discs ever need replacing.

Two angles
15° or 20°: choose your edge
A 15° angle gives a finer, sharper edge, ideal for precision cutting. A 20° angle gives a stronger, more durable edge, better suited to everyday cooking.

Precision
Locks your blade in place
The magnetic block keeps the angle the same on every pass, so the edge comes out even along the whole blade.
Why a rolling sharpener
Rolling sharpener vs a pull-through sharpener
| Rolling sharpener | Pull-through sharpener | |
|---|---|---|
| Choice of 15° and 20° angles | ✓ | fixed angle only |
| Diamond-coated sharpening disc | ✓ | often low-quality stones |
| Ceramic disc for the finishing pass | ✓ | some |
| Gentle on the blade, no chipping | ✓ | ✗ |
| Easy to use, no skill needed | ✓ | ✓ |
