Mikawa Nagura - Massive Asano Stamped Koma Japanese Natural Stone

The Koma Mikawa Nagura is a premium Japanese whetstone, renowned for its ability to refine and polish edges to razor sharpness. "Koma" signifies its fine grade, while "Mikawa" refers to its origin in Japan's Mikawa region, famous for exceptional sharpening stones.

Used as a slurry stone, it generates a fine, creamy slurry when rubbed against a base whetstone, enhancing precision and achieving a mirror-like polish. Prized by craftsmen, chefs, and woodworkers, it is ideal for honing high-carbon steel and traditional Japanese blades. Its rarity and artisanal quality make it both a functional tool and a valued collector's item.
