Thread: Curve on a norton set of stones. Maybe.

I just got a set of Norton Wet Stones (220/1k combo, and 4k/8/ combo) in the mail a few days ago and started experimenting with them and noticed that at the corners of the 220/1k stone do not touch when the other stone is layed (ever so gently) on top of it. to some degree it is on both stones. What would the experienced decision be? should i send them back or is there a way to correct them my self. Or is this just a trait of the stones? I dont have any idea. I'm new to this whole experience.

Not to mention they aren't very square. But that's just something that bothers me as a mason.
