imarku Rolling Knife Sharpener, ABS

If you want a guided way to maintain kitchen knife edges, rather than a basic pull-through sharpener, this rolling design offers preset magnetic angle guides and two diamond discs. You secure the knife against the holder, roll the sharpening disc along the edge, then flip the roller to use the honing disc. The setup gives you a defined process, though choosing among its four angles means matching the guide to the knife and the edge you want.

Key specifications

The sharpener has a durable ABS body, a magnetic knife holder, and two replaceable diamond discs: 400 grit for restoring a dull edge and 1000 grit for honing and polishing. Four preset angles cover different uses: 12° and 13° for sushi, sashimi, paring, and slicing knives, 15° for santoku, chef knives, and most kitchen knives, and 20° for cleavers and outdoor knives.

The downward-facing blade design is intended to keep the edge pointed away from your fingers while sharpening. Magnets hold the knife in place, while the roller provides the back-and-forth motion. Those features make the process more guided than freehand sharpening, but you still need to choose the angle that suits your knife. The product information does not specify fit for every blade shape, so a knife that does not sit securely against the magnetic holder may not work well with this setup.

Who it’s for

A solid pick if you want a repeatable sharpening routine at home and use knives that match one of the four preset angles. For example, you could secure a chef knife at 15°, roll with the 400-grit disc to work on a dull edge, then turn the roller to finish with the 1000-grit disc. That two-stage approach is more deliberate than a quick, single-pass sharpener, and the angle guides reduce the need to estimate the angle by hand.

From the way it is set up, this is aimed at edge maintenance rather than a fully adjustable sharpening system. It might not be a great match if you need an angle outside the listed choices, or if your blade cannot be held flat and steady by the magnets. The product also doesn’t provide details about compatibility with every knife profile, so that’s a practical point to consider before choosing it.

What’s included

The product is described as a rolling sharpener with two replaceable diamond discs, in 400 and 1000 grit, and it comes in a gift box. The discs serve different stages of the process: the coarser one is intended to restore dull edges, while the finer one is for honing and polishing. Replacement discs are mentioned, but the listing does not explain how to obtain them separately.

Questions before you buy

Which angle should you use? The listed guides pair 12° and 13° with sushi, sashimi, paring, and slicing knives, 15° with santoku, chef, and most kitchen knives, and 20° with cleavers and outdoor knives.

What do the two grits do? Use the 400-grit disc to restore a dull edge, then the 1000-grit disc to hone and polish it.

Does the magnetic holder replace careful setup? No. It is designed to hold the knife firmly, but you still need to select a suitable preset angle and make sure the blade sits securely before rolling.

Buying verdict

Choose this imarku sharpener if you want preset angles, a magnetic holder, and separate discs for restoring and finishing an edge. It suits a home routine where your knives match those guides and you’re comfortable following a two-step process. Skip it if you need a wider choice of angles or can’t confirm that your blade will sit securely in the holder, a simpler sharpener may be less setup, while a more adjustable system would better suit less common edge requirements.
