This Japanese Coarse Whetstone Set is ideal for the rough sharpening of bonsai tools and gardening blades. Coarse whetstones are typically used as the first step in the sharpening process to restore a dull or damaged edge. They efficiently grind down nicks and reshape the cutting edge before refining with finer stones.

Whetstones are preferred by many professionals for their precision and control, offering a more even and longer-lasting edge compared to mechanical sharpeners. Properly sharpened tools cut cleaner, require less force, and reduce damage to both plant and blade.
