Abstract: A safety razor includes a handle assembly elongated along a longitudinal axis, a blade head assembly pivotably connected to the handle assembly and having a first blade set thereon, the first blade set extending generally in parallel with the longitudinal axis. The blade head assembly can be releasably connected to the handle assembly to facilitate replacement. The blade head assembly can include a second blade set, the second blade set extending generally in parallel with the longitudinal axis, the first and second blade sets arranged facing away from each other such that the shaving direction of the blade head assembly can be altered by rotating the safety razor about the longitudinal axis. The safety razor can further include a biasing element for resisting pivotal motion of the blade assembly about the longitudinal axis and a control mechanism operable to selectively limit the pivotal motion of the blade head assembly.

Abstract: A handle extension for a handheld razor or applicator pad comprising a fixed angle elongated body having a handle at one end for holding and manipulating said fixed angle elongated body and a gripping head at the opposite end for releasably fastening said handheld razor or applicator pad.

Abstract: A bladeset for a hair clipper includes blade teeth configured to guide hair strands toward a cutting zone and to retain hair strands in the cutting zone. By more effectively guiding and retaining the hair strands into the cutting zone, more complete hair cutting may be achieved. Another feature of the present self-cutting hair trimmer is a housing configured to provide a cutting line associated with a generally elongate handle, which in turn provides a bladeset angle of attack substantially perpendicular to hair to be cut on all parts of a self-user's head or a subject's head when the present trimmer is held by a user in either hand.

Abstract: A blade cartridge for a wet shaving device comprises a housing including a lower housing member and an upper housing member cooperating to define a cavity. First and second blade assemblies are disposed within the cavity. Each of the first and second blade assemblies includes at least one blade defining a cutting edge, wherein the cutting edge of the blade of the first blade assembly generally faces the cutting edge of the blade of the second blade assembly to permit bidirectional shaving.

Abstract: In-line razor-blade shaving devices feature two sets of razor blade strips pointing inwardly in opposite directions. The devices are designed for safely and rapidly shaving hair from large body portions such as legs and arms. Each device features an elongated handle arranged in line with an elongated bi-directional razor blade head. Each set of razor blade strips in the head may be provided with one or more straight razor-sharp edges, which point in the same direction, while the blade edges of the two sets point inwardly toward from one another, generally in opposite directions. The edges of blade strips of the two sets may be arranged in one common working plane, or each set may be in its own working plane, with the planes at an angle to one another. The working planes are defined by the elongated front and rear guard surfaces of the blade-edge guarding system on the face of the razor head. These guard surfaces contact a user's skin before and after the razor-sharp edges to help ensure safe shaving.

Abstract: Razors adapted to support a razor head during shaving while permitting the razor head to move relative to the razor in response to forces encountered during shaving. Preferred embodiments allow a razor head to swivel and also to pivot about an axis normal to a central axis of the razor and normal to an imaginary axis defined by the points of attachment of the razor to a razor head. According to another aspect, an engagement arm comprises a novel slot for controlling the movement of the engagement during shaving, as well as during loading/unloading of a razor head. Embodiments of this invention enable the razor head to maintain optimum shave relation with the skin regardless of the angular differences between the cartridge head, razor handle/grip and shaving motion during shaving.

Abstract: A folding disposable razor includes a shaving head which folds into the razor handle and is aligned with the handle when in an open or extended position.

Abstract: A straight razor has a handle portion and a disposable multi-blade assembly with at least two blades as the cutting edge on at least one of its sides. A molded guard portion at the bottom of the blade portion prevents the blades from cutting into the skin by keeping the cutting edge limited to the surface in common among the sharp edges of the blades and the bottom guard portion. The blade assembly may be connected to the handle by a pivotable blade holder attached to the handle. The blade holder is attachable to disposable blade assemblies at one end of the blade assemblies. A tube-shaped handle may be directly attached to the blade assembly that slides over the blade to form a handle on either ends of the blade. The handle and the blade holder portions may be made of disposable materials and the blade assembly is permanently attached to the blade holder so that the entire multi-blade straight razor is disposable.
