Granite

    I have a remnant piece of granite from the counter I had professionally installed. I want to use it on a small counter. The edges are rough from the cutting the pros did. I don't want it to be highly polished like what the the pros did. I was wondering if it is possible to sand the sharp edges off of the remnanat with a dry sander working my way from 50 grit and up? If it is possible can you recommend a dry sander to use?
