Nakayama Awasedo is a high-quality natural finishing stone, prized by professional chefs, woodworkers, and craftsmen who demand precision and longevity in their blades. Sourced from the historic Kato mine in Kyoto, this stone provides an exceptionally smooth sharpening experience, creating a razor-sharp edge with a refined polish.

Unlike synthetic whetstones, Nakayama Awasedo features a unique natural grit structure, allowing for better edge retention, superior control, and an unparalleled sharpening feel. Whether you're refining a high-carbon Japanese kitchen knife, tuning a delicate woodworking plane, or honing a fine chisel, this stone ensures peak performance for your tools.

If you’re curious about natural stones but hesitant due to their high price, we offer a more accessible option—smaller pieces known as "Koppa."
These may not fully satisfy those already experienced with natural stones, but we plan to gradually expand our selection of standard-sized stones in the future.
Of course, all our stones are authentic and sourced directly from Kyoto, Japan, ensuring genuine quality.
