MITSUMOTO SAKARI MS-371-FR/IT Double-Sided Whetstone, 1000/3000 Grit

The double-sided 1000/3000-grit surface gives you two stages of sharpening in one whetstone: use the coarser side for dull knives, then the finer side for sharpening and polishing. That makes it a practical choice for maintaining steel kitchen knives at home.

A natural bamboo base with non-slip rubber helps keep the stone steady on the work surface while you sharpen. The stone is made from aluminium oxide, and the recommended grip angle is 15–20 degrees for even pressure.

Would you rather have one stone for both sharpening and finishing than choose between separate grits? The MITSUMOTO SAKARI combines both surfaces in a single setup, with a water-soaking preparation before use.

What you’ll notice day to day

The two grits let you move from restoring a dull edge to refining it without changing to a separate stone. Start with the 1000-grit side when a knife needs sharpening, then use the 3000-grit side for a finer finish. Before sharpening, soak the stone in water for five minutes to prepare it for use.

The bamboo base and non-slip rubber are useful when working through a sharpening pass: they help hold the stone in place as you guide the knife. Aim to keep a consistent angle within the recommended 15–20-degree range and apply even pressure. It is intended primarily for steel kitchen knives, ceramic knives are not recommended for use with this whetstone. For serrated knives, a sharpening rod of a suitable size is recommended instead.

Key points

This is a water sharpening stone made from aluminium oxide, with 1000 and 3000 grit on opposite sides. The coarser surface is suited to sharpening dull tools, while the finer surface is for sharpening and polishing. Having both on one stone offers a straightforward alternative to buying separate single-grit stones, particularly for someone who wants to handle routine sharpening and edge finishing with the same tool.

The non-slip bamboo base supports a steady working position, while the two-sided format makes it easy to switch between the stages by turning the stone. Customers describe the sharpener as effective, including for keeping Japanese knives ready for use, some also say they are happy with its value. These are buyer impressions rather than a guaranteed sharpening result, so the outcome will depend on the knife and sharpening technique.

Everyday use

Set the base on a stable work surface, soak the stone in water for five minutes, and use the appropriate grit for the knife’s condition. Keep the blade at a steady angle and use even pressure as you work along the edge. The 1000-grit side is the starting point for dull knives, the 3000-grit side provides the finer sharpening and polishing stage.

This format suits a home kitchen where steel knives need regular edge care, without adding a separate finishing stone to the sharpening setup. Its two grits make the choice of side clear, while the non-slip base helps keep the stone positioned during use.

Final verdict

Choose the MITSUMOTO SAKARI MS-371-FR/IT for a practical, two-stage approach to sharpening steel kitchen knives. Its 1000/3000-grit aluminium oxide stone combines sharpening and polishing, and the bamboo base with non-slip rubber helps create a steadier working setup.
