Suehiro Maido MG1000-1 Magnesia Whetstone [Natural drying for 15 years] [Limited stock] Sharpening stone (Regular Size #1000)

Hard and smooth sharpening edge and sharp finish like natural whetstone. This Suehiro original magnesia whetstone was developed over 15 to 20 years and made using a unique manufacturing method. Production ended with the first lot and will not be produced again. This product is manufactured by cold curing with WA abrasive using magnesium oxide as a binder, then aged for 15 to 20 years in storage. Hard and crisp whetstone surface ensures a smooth whetting touch. For instant results with extra sharpness, please use the mud from Nagura whetstone (optional, for finishing). This product is wear-resistant and lasts longer than normal whetstones while maintaining a smooth whetting touch. The quality of this product is assured by rigorous testing at high temperature (100℃) and dry conditions for synthetic products. Color unevenness and patterns might occur as a result of storage at room temperature. This does not affect performance.

• Discover the MAIDO series from Suehiro—a collection of premium Japanese whetstones born from tradition, precision, and long-term material refinement.
• Each stone in the MAIDO lineup is crafted using the Magnesia bonding method and undergoes an extraordinary natural air-drying process of over 15 years. This rare approach results in a dense, highly stable structure that offers fast cutting speed, excellent sharpening feel, and consistent tactile feedback.
• Because Magnesia is a cement-like material, fine hairline lines may appear on the surface. These markings are a natural outcome of the material’s dryness and density—similar to subtle patterns seen in cured concrete. They are not structural flaws and have no impact on sharpening performance.
• Designed with splash & go convenience, MAIDO whetstones require no soaking—just apply water and begin sharpening. Blending time-honored Japanese craftsmanship with reliable daily usability, the MAIDO series is ideal for users who demand durability, precision, and ease of use in every sharpening session.
