@Monika - I don't mind using a callus shaver at home. But then again, I'm way too cheap to pay for a pedicure too, so that might be part of it for me!
Anyway, I have a pedicure shaver I bought at the grocery store, and I've never had a problem with it. I've never cut myself with it either, thankfully.
I use it on myself about once a month, and I do so very, very carefully. I always use it right when I get out of the shower to make sure my feet are nice and soft. I never bother to soak in Epsom salt first though, it just doesn't seem necessary.
