Abstract: A trimmer includes a blade connection portion and a handle, and a blade is engaged with a recess defined in one side of the blade connection portion. A C-shaped clamp has two ridges extending from two insides thereof and the two ridges are slidably engaged with a first groove defined in the other side of the blade connection portion and a second grooves defined in an outside of the pattern block so as to sandwich the blade between the pattern block and the blade connection portion.

Abstract: The invention provides a razor having a retaining mechanism adapted to receive a blade longer than the mechanism for retaining the blade so that one or both wings of the blade extend past the retaining mechanism to provide a small straight razor. Additionally, the blade is positionable within the retaining mechanism so that its wing can be extended from one or the other side of the retaining mechanism. The retaining mechanism for the blade has a pivotably-attached handle to allow ergonomic adjustment of the shaving angle. The blade and retaining mechanism have associated mechanisms for retaining and aligning the blade in the retaining mechanism.

Abstract: A hand operated tubing cutter adapted to apply a selectable force to tubing to be cut, with the cutter having an elongate, substantially "C" shaped body member and defining a recess for receiving a piece of tubing to be cut. A spaced pair of rollers is operatively mounted in the central recess, directly against which rollers a piece of tubing to be cut is to be placed. An elongate cavity is disposed in the body member in substantial alignment with the pair of rollers, and an elongate ram member is slidably disposed in a non-rotatable manner in the elongate cavity, one end of which ram member supports a cutter wheel. The cutter wheel is rotatably supported in an opposed relationship to the rollers, and a rotatable adjustment device is located on the body member at a location comparatively remote form the rollers. A compression spring is disposed in the body member and operably interconnected with the ram member.

Abstract: A shaving system includes a platform member with a support surface that has a plurality of apertures therein and guard structure integral therewith and disposed forwardly of the support surface, a cap member with a plurality of post elements for disposition in the apertures in the support structure, a primary blade member having a planar body and a cutting edge, a secondary blade member having a planar body and a cutting edge, each blade member having a plurality of apertures and at least two of the apertures having spaced locating surfaces for positioning engagement with the post elements, and a plurality of discrete spacer members disposed on the post elements and between the primary and secondary blade members. The post elements extend through the apertures in the blade members, the spacers and the platform member and preferably are mechanically deformed to secure the primary and secondary blade members with their cutting edges in spaced parallel relation in a fixed shaving geometry.

Abstract: There are provided razor blades of the type where one or two blades are provided in a housing of molded plastic which defines the shaving geometry. In the blade system of the invention the lower base member of the unit has a guard member in front of the cutting edge of the forward blade and another member behind the blade or blades, which members together define the shaving system plane, the geometry of the shaving system including the accurate position of the blade or blades being determined by said lower member, the upper cap member which is attached to the base member, serving only to complement the lower unit and to press on the blade or blades, and for attachment to a suitable razor handle.

Abstract: A razor blade unit has a pair of single edged blades mounted between a base member and a cap member with a spacer between them. The spacer has fingers extending forwardly from a spine located to the rear of the blades to define channels between the fingers. These channels cooperate with holes at the rear of the unit and additional holes passing through the base member and the cap member to facilitate the removal of shaving residue from between the cutting edges of the blades. Additional holes communicating with the channels in the spacer are provided in each end of the razor blade unit to permit rinsing of the residue from the holes and from between the blades by applying water through these end holes.

Abstract: A safety razor comprising a handle portion, a platform portion molded integrally with the handle portion, and a cap portion molded integrally with the platform portion, a hinge portion interconnecting the platform portion and the cap portion, the cap portion being adapted by flexure of the hinge portion to overlie the platform portion, the cap portion being adapted for connection to the platform portion to securely fasten the cap portion to the platform portion.
