They work. They're not the best but they do work. You do have to make sure that they are flat and they have a tendency to leave deeper scratches than a diamond plate. Also, with use, you need to continue to check to make sure that is still flat.
I should've included this question as well: what is the best method to flatten the flattening stone? And should I do this before I use it? And how will I know when it becomes flat again in the future??
W/D sandpaper or loose silicon carbide on a flat surface--ideally in a container. Whether you need to do it before first use will depend on whether or not yours comes flat. You can check this with a straight edge on the lapping surface holding both up to a light and looking for gaps.
If it's anything like the naniwa one I got you may want to take off any sharp or square corners also. I lapped mine on very low grit w&d on a piece of glass. Didn't think much of it so brought a d8c
Glass or a flat tile with sic powder. One tile is cheap at a home improvement store. Couple of bucks.
Thanks bud. How much sic should I dump on it? Do I mix it with water? I already have a basic understanding of that method but this is all new to me. Could you tell me a little bit more?
I tried to go that route years ago and found that the tile was far from flat so check it with a straight edge (you should be able to find one since you're in a home improvement store) before purchasing it.Quote:

I recently purchased a SR and plan to buy a Norton 4000/8000 hone. I had initially plan to purchase the Norton flattening stone as well but I'm second guessing this idea. Should I stay away from the Norton flattening stone? What would you recommend?
Dmt d8c or atoma 400. Personally prefer the atoma as its far lighter doesn't stick and can buy replacement grits for it. Brought the 1200 replacement and stuck it on the back for a double sided hone
Don't mean to jack the thread, but what is an ideal grit to lap a 12k stone?
This may surprise you but the above-mentioned DMT8C (325 grit) or the Atoma 400 both are just fine (pun intended) for lapping a 12k synthetic hone.
I have a Norton flattening stone, but it's far from flat!
