| 181 | Lamina cutter | US10830366 | 2004-04-22 | US07533595B2 | 2009-05-19 | Anthony J. Domenico |
| A lamina cutter includes a handle with a blade having a cutting edge mounted thereon. A guard member is affixed to the blade, and is positioned at a distance from the handle to establish a channel having a width “w” therebetween. The blade then extends between the handle and the guard member to present its cutting edge across the width of the channel. In use, a lamina (e.g. a sheet) having a thickness “t” (wherein “t”<“w”), is advanced through the channel and against the cutting edge to cut the lamina. | ||||||
| 182 | Apparatus for repairing a wall covering | US11977850 | 2007-10-25 | US20080052919A1 | 2008-03-06 | Francisco Lucero |
| A cutting implement has a body with a top and a bottom and one or more blades extending outwardly of the bottom and defining a closed cutting path. In one embodiment, the implement has a cutting depth control. The cutting implement is particularly useful in cutting sections of wall covering. During use, the cutting implement is located adjacent a wall covering so that the blade(s) surround a damaged portion of the covering. Force applied to the top of the implement drives the blade(s) into the covering, creating a severed portion including the damaged area. The severed portion is removed and is preferably replaced by a replacement section of the same size cut with the implement from replacement wall covering. | ||||||

| 185 | Landscape utility knife assembly | US10897761 | 2004-07-23 | US20060016306A1 | 2006-01-26 | Clemente Conde |
| A landscape utility knife assembly discloses a single tool that can puncture the middle of a landscape liner and make the incisions necessary to place plants in the middle region of a landscape or garden area. The knife assembly consists of a replaceable blade and housing. The housing is composed of three regions: a handle region, a blade region, and a penetration region. These regions, which compose the housing, are arranged geometrically to form an acute angle. The tip of the penetration region forms a sharp point that can puncture a landscape liner. The penetration region is adjacent to the blade region and serves also to guide the liner into the replaceable blade that is exposed and recessed at the vertex of the angle formed by the housing. | ||||||

| 196 | Floor laying tool | US968078 | 1978-12-11 | US4236956A | 1980-12-02 | Donald A. Harrison; Howard A. Lanier |
| A floor laying tool utilized in installing synthetic floor materials such as vinyl sheet flooring adjacent walls. This floor laying tool is used to lay vinyl type flooring materials on a subfloor. The tool includes a handle, a downwardly projecting shaft connected to one end of the handle, and a working plate portion. The lower end of the downwardly projecting shaft is connected to the top of the tool's working plate portion. The tool's working plate portion is generally in the shape of a triangle with rounded corners. The first corner is connected to the downwardly projecting end of the shaft with the other two corners positioned equidistant from the first corner. The plate portion and rounded corners are utilized to bond the vinyl to the subfloor along the edges of a baseboard. | ||||||
| 197 | Auxiliary device for laying flexible wall and floor coverings | US856371 | 1977-12-01 | US4143463A | 1979-03-13 | Erich Trankle |
| An auxiliary device for laying flexible wall and floor coverings includes an elongated angle plate having a supporting surface for the material to be cut to size and a pressure strip having a lower pressure surface of approximately the same length as the supporting surface and which has a cross-sectional profile which is configured to complement the profile of the supporting surface. The supporting surface has at one end a wedge-shaped end portion, the outer edge of which defines a supporting edge, and a cutting edge defined at its opposite end, which edges lie in a base plane. The angle plate also includes a part having a locating edge disposed parallel to the cutting edge. The angle plate in cross-sections lies substantially within an imaginary triangle, with its cutting edge, supporting edge and locating edge passing through one corner of the triangle. The device is particularly useful in ensuing that the floor and wall coverings are cut cleanly and accurately to the desired size, in a relatively simple manner. | ||||||
| 198 | Plastic scoring tool | US591173 | 1975-06-27 | US4010542A | 1977-03-08 | Philip E. Richardson; Lothar Lenhardt |
| A flat spring steel element has a handle portion, an offset shank portion, and a blade portion defining a symmetrically ground chisel edge. The edge is oriented at 45.degree. to the handle axis and each end of the chisel edge is ground to define two scoring tips. One of these tips has a 15.degree. forward rake angle when the tool handle is held perpendicular the surface to be scored, and the other tip has a similar rake angle when the tool handle is held at a slightly inclined position relative to such surface. | ||||||
| 199 | Crease cutter | US3739473D | 1971-12-03 | US3739473A | 1973-06-19 | WILDMAN J |
| A novel pressure cutting device of simple construction and improved safety to the user. It is a novel combination of handle and cutting edge, fabricated of wire. A cutting edge is formed in the wire and is confined to a rounded portion or curvature in the wire. The cutting edge is formed so as to face away from the curvature in the wire. The cutting device can be drawn across paper or any other thin and/or flexible sheet material in any desired pattern to score the paper and facilitate tearing or separation of the paper according to the scored pattern. The device is ideally suited to cut out news items from newspapers and magazines, to open packaged foods such as meats and cheese, to prepare pages in photograph albums for insertion of pictures, to cut out colored paper in any desired design, etc.
