The invention relates to a razor head comprising a cap 26 having two elongated surfaces, each with longitudinal and lateral dimensions. One of the surfaces is curved. The razor head also has a platform 22 having elongated surfaces adapted to conform to those of the cap. A flexible curved shaving blade 28 and a pair of tandem straight shaving blades 30 and 32, each blade defining a plurality of locating holes are disposed between the cap and platform and are contained therebetween to conform to the elongated surfaces thereof. The cap also has a plurality of locating pins 34 and 36 extending therefrom to the platform through the holes defined by the blades. The pins have parallel axes. Pins 34, associated with the curved surface, are oriented at an angle to a plane normal to an axis of curvature of the curved surface of the cap. Both pins 34, and pins 36 associated with the straight blades, are oriented at an angle to a plane lying along the longitudinal dimension of and normal to the respective elongated cap surface to which they are attached. The above-described pin orientations provide close alignment tolerances perpendicular to the cutting edges of the blades, i.e., the lateral dimension, but allow some longitudinal dimension alignment gap parallel to the cutting edges, for ease of manufacture. Methods of manufacture are also disclosed.
