This Kongo Toishi Sharpening Stone is a 120-grit coarse whetstone made in Japan for heavy-duty sharpening and blade repair. Its aggressive surface cuts quickly and efficiently, making it ideal for reviving heavily dulled edges or shaping new bevels. Crafted from highly abrasive synthetic materials, it offers reliable and consistent sharpening results for a wide variety of cutting tools.

The stone is ideal for the first stage in sharpening workflows, especially when working with knives, chisels, plane blades, or other steel tools that have become chipped, rounded, or blunt from extended use. With just water as a lubricant, it provides strong abrasion without requiring oil or complicated setups.

Product Data:
• Dimensions: 20cm x 5cm x 2.5cm
• Grit Level: #120 (coarse)
• Material: Synthetic ceramic abrasive
• Type: Waterstone (use with water)
• Country of Origin: Japan

To use, soak the stone briefly in water until air bubbles stop rising. Position on a non-slip surface or sharpening base. Hold the blade at the correct angle and stroke evenly across the stone with consistent pressure. Rewet as needed during use to maintain a slurry and avoid clogging.

After use, rinse thoroughly to remove residue and allow to dry completely in a well-ventilated space. Avoid direct sunlight or high heat when drying. Store in a cool, dry location. Do not use with oil. Keep out of reach of children.
