Professional-grade sharpening stone – single stone model (includes dedicated rubber base). This simple yet high-quality sharpening stone is ideal for those who prioritize the inherent performance of their tools. A sharpening stone is an essential item for restoring the sharpness of blades when they become dull. This product comes with a dedicated, non-slip rubber base to prevent movement during sharpening. The stone remains firmly fixed even during wet work, allowing for safe, smooth strokes and even force distribution to the blade. We have eliminated unnecessary ornamentation to focus on the quality and ease of use of the stone itself. This cost-effective model is perfect for replacements, additions, and DIY projects.
• A “Corundum Stone” recognized by professionals delivers exceptional results. This product uses “Corundum (alumina),” a mineral second in hardness only to diamond. It provides exceptional sharpening power, quickly sharpening blades from stainless steel knives to high-hardness high-speed steel chisels due to its composition of extremely hard particles. This also shortens work time and reduces fatigue. It also boasts high durability and flatness retention, resisting wear and exhibiting minimal “settling” – where the stone itself wears down and becomes uneven – during sharpening. Its ability to maintain a flat surface makes it suitable for precision planing and sharpening of tools like planes and chisels. The uniform particle size minimizes unnecessary scratches on the blade, resulting in a consistently sharp edge.
• ■ #400 (for coarse sharpening). Use: Correcting blade chipping, changing blade shape, removing rust, or initial sharpening of very hard blades. Main compatible blades (limited to metal excluding titanium): Tools with thick blades used roughly, or blades with high hardness requiring sharpening power. Outdoor/agricultural tools (prone to chipping): Axes, billhooks, sickles, pruning shears, lawn shears. Thick cooking knives (for major corrections): Deba, Ko-deba, Aji-kiri, Sake-kiri, Usuba, glass knives, stainless steel Chinese cleavers. Special/high-hardness tools (requiring sharpening power): Ice carving chisels (due to harsh use environments). High-speed steel chisels/planes (initial sharpening when medium-grit stones are too slow due to high hardness).
• ■ #1000 (for medium sharpening/basic use). Features: A standard grit that balances sharpening power and finish. If you have one stone, this is sufficient to restore sharpness for most household needs. Made of corundum, it sharpens blades more quickly than conventional stones.
• 【Purpose/Use (#1000)】 “If in doubt, start with this one. The essential stone for restoring daily sharpness to household knives and professional tools.” • Daily maintenance: Use for regular sharpening when you notice the blade has become dull. • Removing scratches after coarse sharpening: Smooth out deep scratches left by #400 grit and refine the blade edge. • Blade setting (full sharpening): Restore a dull edge to a sharp one, creating a “blade” that bites into food.

【Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device's requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.
