This is a rare Honzan Aito Ōhira Renge Suita whetstone.
Good renge (lotus) patterns are evenly distributed across the entire sharpening surface, and stones with such balanced renge have become increasingly difficult to obtain in recent years.
Although the stone has a dense feel, it remains relatively soft to the touch. During sharpening tests, it consistently produced a fine, creamy-gray slurry. It also provides excellent cutting performance with a smooth and very controlled feel, allowing for effective achievement of high-quality kasumi finishes.
The brown lines visible on the surface are kesuji (natural hair patterns), not suji (toxic lines).

Suita (Suita)
A wonderful stone for planes, chisels, saws, razors, and kitchen knives.
The Ōhira mine (大平山), where the famous Renge Suita was mined, belonged to the Ishihara family (Ishihara, Ishihara) even before World War II. This family owned the mine and organized the mining operations. They were not actively involved in retail trade; the extracted stone was sold to large wholesalers in Kyoto. The most famous buyers were:
Hatanaka Toishi (畑中砥石店) – the largest wholesaler; Maruka; Ozukuya, and other Kyoto merchants. Many stones bearing Hatanaka seals were indeed mined at Ōhira.
In the 1970s and 1980s, industrial mining virtually ceased. The main reasons were the depletion of accessible seams, the difficulty of extraction, and the economic unprofitability.
After this, the mine owners periodically permitted the clearing of old workings; the collection of collapsed blocks; Limited production of small batches; sometimes batches from old stockpiles are released onto the market.
Therefore, modern Ōhira is rare and usually expensive. Ōhira is the source of many of the most famous stones: Awasedo (a fine whetstone), Uchigumori (the best for polishing and sharpening swords), Suita (Shiro Suita), Renge Suita, Karasu Suita, and Nashiji Suita.
The red "Renge" has become something of a calling card for Ōhira.
