Review on 🔧 Revolutionary Norton Flattening Tool Enhances Waterstones Efficiency by James Ramirez

Some reviewers have complained that their stone isn't flat, but I've had better luck. I've smoothed a rough rock and several fine rocks with equal success. The stone removes a lot of material in twenty passes. One of my whetstones became very bulbous but did the job very well. Like any other product, if it arrives defective, simply return it or exchange it. I personally think this is a worthy product for a stone. Updated August 21, 2018: I originally gave this stone a five star rating, but I downgraded it to two stars. After four uses, the alignment surface became concave like a "U" shape. I noticed this when the stone I was leveling became even less flat. I can clearly see the curvature of the stone in the middle. Yes, I used the stone correctly. Yes I let it dry and yes I kept it in a case, I will call Norton and see if they replace the stone.
