They do the job but are very thin not sure yet how long they will last, more feed back later on that, also I thought I was buying a product from us only find it came from China, mixed thoughts.
Nice to deal with fast delivering
Excellent for establishing an edge.
These are good stones with a solid bite on hardened steel but they tend to wear fairly quickly. The non-diamond stones may not cut hardened steel as quickly but will offer more use in the long run. I lubricated them with water while using and was happy with the results. Very dull carbon steel (5160, 52100, etc) these work very well
Best product by far i have come across, the stone does the job but i prefer the diamond coated stones are better for my knife.
So easy and mobile
