For Tools

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
