How does a credo blade work?

blade CREDO

A credo blade functions much like a fruit peeler, and tends to remove callous with a scooping action, rather than shaving it off slowly (how a professional podiatrist will remove callouses). The use of credo blades on calloused skin tends to result in excessive removal – too much removal. And too much removal will cause your skin to be irritated which in turn causes your body to produce more callous to protect itself.
