A raised portion extends over that area of the holder situated centrally with respect to the cutting units, such portion being raised with respect to the periphery of the holder. Desirably such raised portion of the holder gradually slopes downwardly towards the periphery of the holder. An adjustable skin-tautening device is mounted at the periphery of the holder.

Abstract: A hand knife has a removable blade. Side plates are spaced apart on opposite sides of a main frame having a rectangular socket in one end thereof. One side plate has a non-circular aperture therein and the other side plate has a circular opening therein. A pin is movable on a transverse axis relative to the main frame and has a non-circular portion in the aperture and a circular portion in the opening. A blade has an exteriorly rectangular end slidable in a predetermined direction to fit the socket. The end interiorly has a keyhole opening, the circular portion of which fits the larger, circular part of the pin and the rectangular portion of which is open ended in the predetermined direction and fits the smaller, non-circular portion of the pin. A spring normally urges the circular portions into interengagement. A button on the pin, when pressed, overcomes the spring and moves the non-circular portion into sliding engagement with the rectangular portion of the keyhole opening.

Abstract: The disclosure is directed to a utility knife which is suitable for mounting at least two different types of blades and which has an improved safety feature. The knife of the invention has an elongated handle, and means for mounting a blade of one type at an end of the handle. In accordance with an important feature of the invention, the mounting means includes means for preventing the mounting of a blade at a given end of the handle when a blade is already mounted at the opposing end of the handle. In particular, in an embodiment of the invention the handle includes a pair of elongated mateable handle elements which conform generally in shape. A pair of blade-engaging units, each of which may be, for example, a suitably sized key or nub, are respectively disposed near the opposing ends of one of the handle elements. A blade-securing pad is disposed near one (only) end of the other handle element.

Abstract: A shaving implement for raising and holding low-lying hairs in an erect position for cutting by a blade edge and for distributing shaving force which includes resilient hair raising means spring mounted on a flange having a skin contacting surface or guard member adapted to distribute shaving force to substantially prevent stretching of a user's skin. The resilient hair raising means have barbed ends projecting beyond and substantially normal to the skin contacting surface of the flange in close proximity to the blade edge.

Abstract: A hand razor assembly consisting of a plastic frame having a downwardly projecting handle with a razor guide adapted to roll the hair stubs into engagement with the blade cutting edge in a manner that will produce a closer cutting shave.The razor blade is positioned within the frame in such a manner so that it extends generally parallel to the skin surface in a substantially conventional manner. The guide is a projection extending generally parallel to the cutting edge of the blade, sharply pointed and positioned in a plane perpendicular to the plane of the blade. The pointed edge of the guide projects above the plane of the blade and is spaced sufficiently from the blade so that it rolls the skin and the projecting hair follicles into engagement with the cutting edge of the blade in a manner substantially similar to a double bladed razor.

Abstract: A hair trapping member for use in electric shavers is disclosed. The member is designed to be mounted on a shaver blade of the type having a recessed central trough-like channel and a plurality of laterally extending, closely spaced cutter bars on each side. The bars, lengthwise of the blade, are separated by laterally extending slots which open both through the sides of the blade and into the central channel. The hair trapping member has an elongated channel-like body element sized to seat in the central channel of the blade. A plurality of laterally projecting tongues extend from each side of the body element, one of the tongues being adapted to be received in each of the slots for trapping and holding hairs entering the slots.

Abstract: A shaving apparatus comprises a holder having at least one cutting element, particularly intended for so-called wet-shaving, and a hair-pulling member including a blade shaped portion movable between the inside and the outside of the holder.

Abstract: An electric razor is disclosed herein having a case housing an electric motor and a gear driving train operably coupled to a moving cutting head. The head includes at least one cutting blade driven by the motor either in a back and forth stroking manner or in a rotary motion. The cutting head is movably carried on the case by an oscillating plate driven by the gear train so that the entire cutting head including the cutting blade or blades moves while the cutting blade or blades are driven in their stroking or rotary movement. Tension rollers are provided about the periphery of the oscillating plate engageable with the skin of the user for stretching the skin to expose more of the hair shaft preparatory for cutting.

The chuck which is provided with an adapter portion so it can be attached to surgical instruments presently in use comprises a slotted body portion having a pyramid locator at the base of the slots into which the notched end of a saw blade is seated by the action of a knurled internally threaded collar carried on said chuck body in cooperation with the teeth of the saw blade.

Abstract: An inexpensive suture cutter is shown in which the cutting portion is a sharpened edge of a wire-like member one-eighth inch or less in diameter at the cutting portion. This wire-like cutting portion has a blunt end to prevent accidental penetration of the skin as the knife portion of the cutter is slid under the sutures which are then cut as the cutting edge is slid along and underneath the sutures. Prior to cutting a length of adhesive tape is placed on and secured to the sutures to be cut and removed. The edge of the tape is placed adjacent or over the proposed cutting path. The sutures are removed by and when the tape is lifted from the skin after the sutures have been severed by the cutter.
