All natural stones in our store have been thoroughly tested by me on Razors, Knives, and Tools. I have included a short description with each stones relative hardness and best use. If a stone has any inclusions or toxic lines, it will be stated in that particular stones description, otherwise there are none. Please email me before buying a stone, and I will try and guide you to which stone suits you and your situation the best.
I strongly recommend that you read our JNS WiKi

IMPORTANT note for All Sharpening stones, Synthetics or Naturals, Seal all your stones that way you are 100 % sure that they hold a life time !
Use can use any waterproof lacquers or simply glue it to wooden or other bases
