Sharpening Service

At Yoshihiro Cutlery, we offer professional knife sharpening and repair services. We can repair virtually any knife or edge and restore the blade's edge beyond its factory sharpness. At Yoshihiro, we professionally sharpen every blade by hand with traditional Japanese whetstones, using trained and seasoned hands.

Unlike grinding wheel sharpening, which can irreparably harm the metallic composition of traditional Japanese and high carbon knives, Japanese water stones are the only materials that can preserve and extend the edges of high-quality knives.

We can sharpen and repair almost every type of kitchen knife blade edge. We also offer a unique premium high-performance custom edge crafting where we put an extreme edge for maximum performance of your knife. Whether you are looking to have a traditional Japanese or Western knife sharpened, we can assess the condition of the knife and determine the type of sharpening or repair needed, based on your personal needs. Depending upon the condition of the knife, we can also fix chips, dents, and other types of defects.

Feel free to contact us with any questions or concerns.

Knife sharpening rates are based on the condition, blade material, and size of the knife. A prior assessment must be made before a quote can be given on items with heavy damage.

We accept knives through walk-ins to our showroom in Redondo Beach, CA, or through mail.

For Single Edged Knives: Uraoshi

Uraoshi refers to the flat rim on the back sides of traditional Japanese knives (single-edged knives). The uraoshi surrounds the Urasuki, the integral concave shape on the back sides of traditional Japanese knives. The purpose of the urasuki is to minimize food sticking to the blade (reducing the drag while slicing), which has the same effect as perforated and hollow-ground blades. It is essential for the rim of the urasuki to be perfectly flat and level for it to have its full effect. Furthermore, it enhances the strength of the blade on the edge of the knife, as well as aligning the unbalanced parts on the back side of the blade. Without the uraoshi, the knife cannot be sharpened to its full potential and will become brittle.
