Quality stone that gets the job done.
Works very well in removing rust without damaging the base & edge. Get a few as it is small and wears out relatively easy.
This product works great for removing surface rust off my ski metal eges without having to take a file to it. It also works on softening the edge on the from and rear edges of the skis
