摘要： The various embodiments of the invention are directed to safety razor heads (120) having intrinsically fenced cutting blades (136, 138) oriented at a high slicing angle to the shaving direction. The razor comprises a plurality of short cutting edges (4) in a spaced relationship across the width of the cutting zone, bounded by leading (112) and trailing guards (104), and oriented at an angle greater than 30 degrees, resulting in enhanced cutting action, improved lubricant and debris flow, and longer life of the cutting edges. Lateral skin tensioning is achieved in one embodiment by the spreading action of left and right oriented cutting edges.

摘要： A manually operated, finger-manipulatable non-electric hair trimming device for shaving nostril hair, ear hair or the like, includes a head structure sized to fit within a small body cavity, such as a person's nostril or ear cavity, which includes a flexible razor blade strip. The head structure has a base portion and a curved guard portion, which preferably has first and second ends which are attached to the base portion. A finger grip portion is connected to the base portion to allow precise manual manipulation of the hair trimming device. The head structure further has a thin, elongated narrow razor blade strip with a razor sharp first edge portion, which may be a serrated edge with razor-sharp notches such as V-slots or may be a conventional straight edge. Alternatively, two razor-sharp edges, one serrated and one straight, may be provided. The razor blade strip preferably has an inverted U-shape, made by flexing it to extend substantially along the curved guard portion of the head structure, which may serve as the blade strip platform. The guard may have fingers which extend beyond the razor's edge with blade-exposing recesses therebetween.

摘要： A safety razor blade unit (2) has blade assembly (5) comprising a plurality of parallel blades (16) mounted on a razor handle (1) by a flexible support structure (4). Each blade (16) consists of an elongate blade element having a forward edge section (50) with a sharp cutting edge (17), and a planar blade section (54) extending rearwardly from the forward edge section (50). The forward edge section is upwardly inclined by bending a blade element blank between press tooling so that in the transition region between the forward edge section (50), which extends back from the tip of the cutting edge (17) by not more than 1 mm, and the planar blade section (54), the lower surface is convex and the upper surface is concave, with the plane (Pt) bisecting the tip being at an angle of 10° to 35° to the mid plane (Pm) of the planar section (54). The blade 16 is positioned in the blade unit (2) with the mid plane (Pm) of the planar section parallel to a tangent plane tangential to surfaces of the guard (26) and the cap (24) of the blade unit. The tip of the cutting edge is at a height of 0.05 to 0.15 mm above the plane (Pn) of the upper surface at the planar section, and to ensure good flexibility the blade cross section has a minimum second moment of inertia not greater than 1.0×10−4 mm4.
