Whetstones / Toishi and Maintenance

In Japanese, whetstones are called “toishi” which translates to “grindstone.” At Hasu-Seizo we carry high-quality, authentic toishi whetstones to help you properly care for your real Japanese knives. We offer a variety of whetstones in all different grits in order to accommodate your sharpening needs, and we offer all of them at prices you can afford.

Keep in mind that the lower the grit count, the more material is removed from the blade. This results in a rougher edge. On the other hand, if you choose a whetstone with a higher grit count, you end up with less of the blade being removed, which translates into a much smoother edge. Chances are good that you already have a specific result in mind when you’re shopping for a toishi whetstone, so it’s good to know a little about grit numbers before you get started.

A Large Selection is Available

At Hasu-Seizo, have a wide selection of knife care necessities such as whetstones and camellia oil. Our products have grits that range from 120 all the way up to 8,000, so you are certain to find a Japanese whetstone that is perfect for you. You can purchase the stones individually or as a set with the base included, as well as maintenance oil, rust erasers, and even just the base if that’s all you need.

If you’re a professional chef or simply love to cook, purchasing well-made knives that are built to last for many years to come should be your goal. It is cheaper in the long run, and it helps make all of the dishes you cook absolute masterpieces.
