Abstract
A shaving blade unit includes a housing having a front edge, a rear edge and side edges extending between the front and rear edges. One or more shaving blades are positioned between the front edge and the rear edge and have cutting edges arranged to define a first cutting region. The shaving unit further includes a discrete trimming blade assembly having a blade carrier with a cap, guard and a solitary trimming blade defining a second cutting region. A clip is arranged to retain the one or more shaving blades on the housing and function as an anode in an anode-cathode cell to inhibit corrosion of the shaving and trimming blades.
