A roller sharpener with a four-angle magnetic base: 15°, 18°, 20° and 22°. The magnet holds the blade while you roll the cylinder along the edge. To change the angle, simply turn the base.

Depending on the model, it comes with 2 or 6 interchangeable discs: diamond for sharpening, stone and polishing for refining. Designed by the RSCHEF brand.

  • 4-angle magnetic base: 15°, 18°, 20° and 22°
  • Blade held by a magnet while sharpening
  • Interchangeable discs: diamond, stone or polishing depending on the model
  • Manual sharpening, no electricity needed
  • Two finishes: dark wood or orange

Once your order has been confirmed, it will be processed within 24 / 48 hours. Our delivery times are 8 to 15 working days.

  1. Position the diamond stone
    Place the double-grit plate (400/1000) firmly on its magnetic base. This guarantees a stable base throughout the entire sharpening session.
  2. Set the sharpening angle
    Press the blade against the magnetised support and choose the angle according to your needs: • 15° for a fine and precise edge • 20° for a stronger and more durable edge
  3. Start with the 400 grit
    Pass the blade ten times on each side, starting from the heel to the tip. This step eliminates imperfections and restores the bite to the edge.
  4. Finish with the 1000 grit
    Repeat the same movements in the slot dedicated to the 1000 grit. Around six light passes are enough to smooth and polish the blade until a mirror edge is achieved.
  5. Clean and store your equipment
    Rinse the blade under clean water, wipe it well, then store your sharpener in a drawer or cupboard within reach.
    Pro tip: Do not apply unnecessary pressure. Let the stone do the work to preserve both the blade edge and the longevity of the sharpener.

The right angle for every knife

Each side of the base corresponds to an angle. 15° for thin-bladed Japanese knives, 18° for Asian knives, 20° for most Western kitchen knives and 22° for sturdier outdoor knives.

The magnet holds the blade against the base: the angle stays the same from one pass to the next, without having to hold it by hand.

From reshaping to finishing

Change the discs according to the condition of the blade. The coarsest diamond grits (240#, 400#) restore a dull knife, 1000# sharpens for everyday use. The stones (600#, 800#, 1200#) refine the edge, and the polishing discs (3000#, 8000#) give a smooth finish.

The 2-disc models cover everyday maintenance; the 6-disc models go from reshaping to finishing.
