I don't know if I believe any of these Tuff Pad type things will work. I just bought Cut n Heal yesterday and all it is is oil and some moisturizers. I just don't see how linseed oil is going to harden and toughen pads. It'll put a nice finish on a cabinet though. And the alcohol ones make the pads feel tough because it dries them out. That can't be good for the feet. Have any of you used one that really coats the pad and makes it more like a callus?
