Abstract: Disclosed is a blade unit for a safety razor, comprising a blade housing comprising a plurality of blades having respective cutting edges lying in a shaving plane and being arranged to exert a cutting action when moved across a user's skin; and a guard in front of the cutting edges and a cap to the rear of the cutting edges, the guard including an elongate lubricating strip, and the cap including a convex lubricating pad having a convex skin-contacting surface and a rear edge curved in a single arc shape along its entirety. A skin-contacting surface of the convex lubricating pad is greater than a skin-contacting surface of the elongate lubricating strip, the convex lubricating pad and the elongate lubricating strip together extend along at least 60% of an outer perimeter of the blade unit, and the convex lubricating pad extends along at least 30% of the outer perimeter of the blade unit.

Abstract: Described is a razor handle in the form of an elongated body. The handle has a razor head end with a structure for connecting to a razor head and a free end opposite the razor head end. The handle further has a lower surface on the same side as the cutting edges of the blades when the razor head is connected to the razor handle and an upper surface opposite the lower surface. On the upper surface there is a first gripping area for providing a first gripping position for a finger or thumb of the user and a second gripping area for providing a second gripping position for the finger or thumb. The first and second gripping areas having textured surfaces and are separated from one another by a smooth area of the upper surface.
