There are three main differences between the different Pitbull shavers: included blade type, included accessories, and features. The Pitbull Silver comes standard with a Carver blade which is specially designed for coarse or thick hair.  The Pitbull Gold AND Pitbull Platinum come standard with our most popular blade, the Forte.  The Pitbull Platinum has all the same features of Pitbull Gold, PLUS a wash indicator, a travel lock function, a premium travel case, and Platinum rinse stand.
