Japanese Natural Whetstones

Japanese natural whetstones represent the highest level of razor honing. We select only stones that we use ourselves every day for restoring and sharpening the kamisori we offer.

All stones are authentic and sourced directly in Japan. Each one is chosen for real-world usability, not for names or speculation.

With many stone types and terms in use, choosing the right stone can be confusing. If you’re unsure what fits your sharpening routine, feel free to contact us—we’re happy to advise.
