Thank you very much for your message. I’ll be happy to clarify the differences for you.

🔹 Stones that require oil lubrication

Boride series T2, PC, and AS-9
All natural stones (Arkansas, etc.)
All diamond and CBN stones (regardless of bond type) from Hapstone, PDT, Jende, KDTU, Venev

🔹 Stones that require water only

On our website, you can also use filters to sort stones by their lubrication type — this makes it easier to find exactly what you need.

We’ll always be glad to assist you as you continue your sharpening journey.

Best regards,

Mario
