Japanese Natural Whetstone Ohira Renge Suita 24' Size *Chunk* 1318g Kyoto

This is a rare Honzan Aito  Ōhira Renge Suita whetstone.

Beautiful renge (lotus) patterns are evenly distributed across the entire sharpening surface, and stones with such well-balanced renge have become increasingly difficult to obtain in recent years.

While it has a sense of density, the stone remains relatively soft in feel. During test sharpening, it consistently produced a fine, creamy gray slurry. It also offers excellent cutting performance, with a smooth and highly controllable feel, allowing you to achieve a high-quality kasumi finish efficiently.

The brown lines visible on the surface are “kesuji” (natural hairline patterns), not suji (toxic lines).

 Please note that these are not for beginner sharpeners since they're harder to use. These are natural stones meaning that every single one of them are different so my measured sizes are not accurate. This is a lifetime investment for people who live sharpening their knives and tools, do not hesitate to ask me your questions.”
