|20140096402||PIVOTING RAZOR - An elastic plate is located between the support portion at the head portion of the holder and the supported portion of the razor head. The outer circumference of the annular elastic portion of the elastic plate is supported by the inner circumference of the annular portion of the support portion. The supported portion of the razor head is inserted into the inner circumference of the annular elastic portion of the elastic plate. As a result of the support structure to support the razor head to be movable from a neutral position against the elastic force of the elastic plate, the razor head can be moved during use from the neutral position to positions in three dimensions against the elastic force of the elastic plate.||04-10-2014|
|20140031847||MEDICAL KNIFE - A medical knife includes a blade plate and a blade portion formed at the distal end of the blade plate. Cutting edges extend from the distal end to the proximal end of the blade portion. Two blade surfaces in the width direction of a back-face portion of the blade portion are formed to gradually increase a distance between opposite side and cutting edge from one of the distal end and the proximal end to the other. The two blade surfaces in the width direction of a front-face portion of the blade portion are formed such that the distance between the opposite side and the cutting edge becomes equal in a zone corresponding to a distal end of the cutting edge and a zone corresponding to a proximal end of the cutting edge, over the entire cutting edge from the distal end to the proximal end of the cutting edge.||01-30-2014|
|20140030964||ELECTRIC CUTTING-TOOL GRINDER - The grinding surface of a grinding stone is formed from a circular conical surface, a drive device for rotation is installed within a housing. The blade of a cutting tool is ground while the longitudinal direction of the cutting tool is aligned with the direction of a generating line of the grinding surface. When grinding the blade, the cutting tool can be aligned with the direction of the generating line of the grinding surface and the blade can be brought in contact with the grinding surface without the handle of the cutting tool and the hand that holds the cutting tool being interfered with the grinder. This is achieved irrespective of in which one of the directions of lines the tip of the blade faces, the lines being obtained by extending the generating line of the grinding surface from both ends of the generating line.||01-30-2014|
|20120023762||HANDLE FOR BLADED HAND TOOL AND RAZOR - A space is provided in a front section of a handle. The space is located between side sections and extends along the longitudinal direction of a grip portion. A finger rest wall extending along the longitudinal direction is provided on each side section. The finger rest walls are provided to sandwich the space in the widthwise direction of the grip portion. Each finger rest wall is formed like a cantilever such that one of the ends in the thickness direction of the grip portion is a free end, and the other end is a fixed end. The space is opened between the free ends of the finger rest walls. The finger rest walls are attached to the side frame sections at the fixed ends. The side frame sections are formed of a material that is harder than the finger rest portion. The finger rest walls are deformed into the space when pressed toward the space.||02-02-2012|
|20100229397||Razor - A razor is provided with a blade member||09-16-2010|

|20100139103||Replacement blade razor - A replacement blade razor including a holder having a head portion, a razor head supported by the head portion of the holder, and a blade member removably mounted in the razor head is provided. The head portion of the holder or the razor head includes a holding mechanism that assists in mounting of the blade member in the razor head by attracting or adhering to the blade member and thus causing the razor head to hold the blade member.||06-10-2010|
|20090204136||Hand Tool - A hand tool includes a holder and a movable head portion to which a blade body is secured. The movable head portion is supported by the holder in a manner movable relative to the holder between an accommodated state Q, in which the movable head portion is accommodated in the holder together with the blade body, and a projected state, in which the blade body is projected from the holder. The orientation N of the blade body in the accommodated state Q and the orientation N of the blade body in the projected state are different from each other. This improves operation of the blade body both in the accommodated state Q and the projected state and reduces the size of a front opening of the holder to provide a compact holder of the hand tool such as a medical edged tool.||08-13-2009|
|20090065386||Support Member for Edged Tool - A support member used in exhibiting an edged tool is provided with a support body and retaining means. The support body is formed by a first sheet and a second sheet being superimposed on each other so that an accommodation chamber is formed between the first sheet and the second sheet. The second sheet is provided inside of outer peripheral edges with an opening which allows the cutting edge of the edged tool to be inserted. The cutting edge of the edged tool which has been inserted into the opening is accommodated in the accommodation chamber so as to be covered by the first sheet and the second sheet. The handle of the edged tool of which the cutting edge has been accommodated in the accommodation chamber is arranged so as to be superimposed on the second sheet. The retaining means supports the edged tool of which the cutting edge has been accommodated in the accommodation chamber on the support body. It is thereby possible to prevent the first sheet from being removed from the second sheet.||03-12-2009|
|20080201962||Scissors with comb - A pair of scissors with comb comprises a first blade having an edge, a second blade openably and closably supported together with the first blade and having an edge and a comb member attached to the first blade. The comb member is provided with a plurality of comb tooth groups with different characteristics from each other. The comb member is attached to and detached from the first blade. The mounting state of each comb tooth group is changed with respect to the first blade, whereby, for example, an extending direction of the comb tooth group is changed based on differences in the direction of eyebrows so that each comb tooth group can be used properly. Since an extending direction of a comb tooth of each comb tooth group inclines, the scissors with comb can be rendered convenient when eyebrows are trimmed.||08-28-2008|
