The softness of a waterstone allows it to quickly develop a fast cutting abrasive slurry. That’s a real plus for honing, but a negative when you start to develop shallow indentations and irregularities in the surface. Norton’s flattening stone, when rubbed across your waterstone’s...

Inexpensive way to get started
This was my first flattening stone. The instructions detail the need to flatten the stone. It will indeed go out of flat and correspondingly dish your sharpening stones. However, I found it to work well when maintained per the instructions with sandpaper.

Worse than useless
Bought this to dress my norton waterstones. It worked OK for the first couple times, but rapidly developed an arch where the outside edges wore down more quickly. Maybe I didn't use it precisely right, but it went out of true very quickly & then dished out my stones. Replaced it with a diamond plate that is absolutely flat & dresses the stones quickly. True, there is a lot more adhesion between the plate and the stones, and I have to stop and wash off the slurry periodically but everything comes out completely flat.

Works great for me!
I use the flattening stone to maintain my Norton sharpening stones. I place the flattening stone on a slab of granite (sink cutout piece) I use as a sharpening station. I work the sharpening stone over it until pencil lines are gone. Usually takes less than 2 minutes. I flatten stones after every other plane blade sharpening.

Great tool
This is a much better way to flatten your water stones than a piece of glass and sandpaper. Highly recommend.

Inexpensive Lapping plate
If you don't want to spend $100+ for a diamond stone to lap your water stones it is a good alternative. Diamond stones are much faster. If you get a diamond stone for lapping get a very course stone (>200 grit). I used this stone to flatten 6 very badly hollowed stones I inherited from my father and it works but it's alot of work. The grooved surface does make it more fragile if you're not working on a flat surface so find one and place some padding underneath the stone.

Makes your waterstones like new again!
I saw some critical reviews of this product which almost lead me to not purchase it. They seem to me totally unfounded. This tool works just fine. Yielded a very flat stone with a decently smooth surface and worked efficiently.

Not worth it.
I do not recomment this stone for flattening. I have used this stone several times and have always noticed that it humps up the middle of my sharpening stone. The problem is that it tends to roll from side to side as you push it back and forth. I use hand planes all the time and I need my shapening stone to be flat so that I get a good edge on the plane blade. I do, however, like to use the back side of this stone to get rid of nicks and dips in the edges of plane and chisel blades. I would not get this to use as a flattening stone, instead get a diamond or granite plate, not as cheap, but better in the long run and more for the money.

It cannot use.
The plane has not come out. It cannot use.

Worthless
I have used this to grind a chip out of a 2 inch blade, It does dish out quickly. When I use it to flatten the 1000,4000, and 8000 grits this stone leaves its grit behind in the slurry. Not the best conditions for sharpening. The stone also cuts really slowly.

Not worth the money
Embedded particles in my polishing stones. Took several hours with wet/dry paper on a piece of glass to get out. The thing dished out too easily. Get a DMT diamond stone for flattening stones. You'll be much happier.

Poor Quality
I purchased the Norton as the water stone set. I watched the DVD and read all the instructions. I soak all the stones and flattening stone at the same time. I was very careful with all the stones and handling. When I went to lift the flattening stone out of the water it broke. It had not even been used yet. Very disappointing.
