Without telling my son I was getting his skates sharpened differently I took his skates to Ultimate Edge and explained the type of skater he was and how he sometimes avoided corners and he just wasn't improving as fast as he wanted to. They explained radius to me and their sharpening techniques. I had heard great things about them and was not disappointed. My son's first time on his "new" skates proved that Ultimate Edge makes a huge difference. I've never gone anywhere else since, and it's a long drive for me to get there.
