Replying to Grinding on Scratches

I have then new Scratch Fs, and I find that after grinding only a little bit the endges under the boot are sooooooooooo much thiner than around the rest, of the ski.
I have been grinding on my blue 1080s ALOt, and the edges are just rounded not almost gone.
If they grind off really fast would they be warrentied? I dont think a company would warrenty that. But the FS's are advertised as a 'freestyle' ski, and adverties there pros grinding on them.... let me know what you think.
Punks not dead.
