great little Stone really does a good job as in it is course enough to not take a long time to get done what you are trying to get done
these are fairly interesting, they are quite fine, fairly small, smaller than I initially anticipated but the quality doesn't seem too bad at all, I ordered 2 and both arrived well wrapped, only a very small chip from one corner nothing that bothered me at all and don't think it happened in transit. the stones themselves are not ground flat, rather signs indicate a saw being used...regardless, the surfaces are quite flat indeed and the sides all quite square and sharp. haven't actually verified with a square but I will. for the price I'm quite pleased...btw shipping was faily speedy, fully tracked. A+ seller here.
