Max Knives SP55 — Double-sided diamond plate 400/1000 with holder

Overview

The SP55 is a double-sided diamond plate mounted on a universal holder. It measures 28 cm by 6,5 cm and is 8 mm thick, with 400 grit on the front and 1000 grit on the back. Length matters as much as grit here: 28 cm let a kitchen blade travel its whole length in one movement, without having to sharpen it in sections. The universal holder will also take a coticule stone if you already own one.

A holder that outlives its own plate

The supplied holder is described as universal, and that is where the SP55 reaches beyond its own abrasive. It keeps the plate in place while you push the blade, but it also accepts a coticule stone, which makes it the base of a sharpening station you can grow: shape on 400 grit diamond, refine on 1000, then finish on a finer stone set in the same place, at the same working height. One base, several abrasives, and a hand that keeps its bearings throughout.

Technical specifications

Plate measuring 28 cm long by 6,5 cm wide and 8 mm thick. Two diamond faces: 400 grit on the front, 1000 grit on the back. A universal holder is supplied with the plate and is compatible with a coticule stone. Those 8 mm make a plate distinctly thinner than the SP54 block, which is 2 cm deep, while keeping the same 28 cm length and the same 6,5 cm width for full-length strokes.

Care

Rinse each face after sharpening to remove the metal particles, including the one you used first. Wipe the plate, then let it dry off the holder before storing it, so that moisture is not trapped between the two parts. The universal holder itself is cleaned under clean water too, especially if you have set a water stone on it and left sharpening slurry behind on the bearing surfaces.
