Sharpi Ceramic/Diamond Knife Sharpener (SH-K-0005)

Sharpi Diamond/Ceramic Knife Sharpener #360/#1000 with Suction Cup – Two-Step Sharpening

The Sharpi Diamond/Ceramic Knife Sharpener #360/#1000 with Suction Cup (SH-K-0005) is a compact, handheld device designed for sharpening kitchen knives and other blades that fit into the guide slots. Two grinding stations combine #360-grit diamond with #1000-grit ceramic, allowing you to restore sharpness and smooth the edges.

The suction cup base stabilizes the sharpener on a clean, smooth surface, making it easier to guide the knife safely. Its compact size and weight of 109.00 g allow you to conveniently store the device in a kitchen drawer or take it with you on a trip.

Diamond #360 – Coarse Sharpening Stage

The first slot uses a diamond abrasive with a grit size of #360. This stage is used to restore the geometry and sharpness of a noticeably dull edge. The knife should be drawn in a smooth motion from the base to the tip, applying light and even pressure.

Ceramic #1000 – smoothing and finishing the edge

The second slot contains ceramic elements with a grit size of #1000. It is used to smooth the edge after the diamond stage and to regularly maintain the knife’s sharpness. Gentle strokes help remove minor irregularities and improve the quality of the cutting edge.

Suction Cup and Stable Operation

Before starting to sharpen, place the device on a clean, dry, and smooth surface, then secure the suction cup properly. A stable position minimizes movement of the sharpener during operation. Guide the blade without excessive pressure, following the direction indicated by the slot design.

Technical Data

Frequently Asked Questions

In what order should I use the two stages of the sharpener?

If the knife is noticeably dull, start with the #360 diamond stage, then move on to the #1000 ceramic stage. For regular sharpening maintenance, using the ceramic stage is usually sufficient.

How many times should you run the knife through the sharpener?

The number of passes depends on the condition of the blade edge. It’s best to start with a few light, even strokes and then check the sharpness. Excessive passes and too much pressure can unnecessarily increase wear on the blade material.

How do you guide the knife correctly?

The blade should be drawn from the base toward the tip in one smooth motion. The knife should remain aligned with the guide, without tilting to the sides. Near the tip, you need to lift the handle slightly to maintain contact between the entire edge and the abrasive elements.

How do you clean the Sharpi sharpener?

After use, wipe the device down with a dry or slightly damp cloth. Metal residue can be removed with a soft brush. Before storing the sharpener, make sure its working parts and base are completely dry.

Is the sharpener suitable for hard steel knives?

The manufacturer states that the sharpener can sharpen knives with a hardness of up to 65 HRC. When working with hard steels, apply light pressure and check the results after a few passes to avoid removing too much material.
