Japanese Sharpening Stone – Rough (#300)

These premium Made-in-Japan sharpening stones are an excellent choice for anyone seeking consistent results, long-term durability, and precise sharpening. Carefully selected for their quality and fine craftsmanship, they are essential tools for keeping your leatherworking blades in top condition.

We offer three grit levels:

• Rough #300
• Medium #1000
• Fine #6000

These versatile, water-based whetstones are designed to handle a wide range of materials, including tempered steel, stainless steel, high-speed steel (HSS), and more.

Tips:

• Flattening is key: Use the rough #300 stone to flatten the #1000 and #6000 stones regularly. A flat surface ensures even sharpening.
• Use with water only: Soak the stone before use, and keep it wet while sharpening. Do not store it soaked, wipe off moisture and air dry in the shade after use.
• Sharpen on a stable, flat surface to prevent slipping.
• Do not rinse off the “sharpening water” from the #1000 and #6000 stones, it acts as a lubricant and helps refine the blade.
• Do rinse off the “sharpening water” from the #300 stone, as the coarse particles can damage fine edges.
