I received my diamond short cut today. I've never had a squeegee sharpener because I've always just replaced the blades. This thing will definitely do the trick. You can almost cut yourself with the edges. The other thing that stuck out to me is that it was unbelievable how one side of the squeegees were drooping down on one side or the other sometimes by as much as an eighth of an inch in the M&R holders. I could never see it with the naked eye partly because I'm about half blind but I think that will help with the printing. I think that will be one my best additions to the shop.
