Some background. Im looking to buy my first honing stone but I'd rather do it locally since where i live custom taxes are nuts. Basically anything over $25 has a 50% tax on it. Tried to get the Norton 4k/8k ones but couldn't find any so far.

I found this , which seems to be Belgian water-stone. Am i correct? I'm going to be picking the stone, is there anything i should be looking for in terms of that would make this stone unusable?
