| 107 | SPRING-LOADED BLADED HAND TOOL | US12489958 | 2009-06-23 | US20090313781A1 | 2009-12-24 | Marvin Gray |
| A force reducing bladed hand tool designed to allow the tool's blade to rotate so that the working edge of the blade is continuously aligned for optimal cutting or scraping with each arm movement. In the first embodiment, the hand tool is a knife with a hollow handle with a longitudinally aligned tension spring located therein. Mounted on the distal end of the handle is a connector with a downward extending spline attached thereto. Pivotally attached to the spline is an elongated blade with a cutting edge. The proximal end of the blade is attached to a coupler which connects at an opposite end to the spring bias the blade inward through the connector and towards the handle. During assembly, a pivot pin is extended through the bore in the spline and a complimentary bore formed on the blade. The pivot pin and the lower slot on the connector enables the distal end of the blade to pivot upward when excessive pressure is exerted on the handle by the user's hand. | ||||||

| A lamina cutter includes a handle with opposite parallel surfaces, proximal and distal ends, and edges that extend between the surfaces and between the ends. Further, the handle forms a groove positioned between the surfaces adjacent the distal end. Also, the lamina cutter includes a plurality of disposable guarded blades. Each guarded blade includes a planar blade member permanently bonded to a guard member. Specifically, each blade member has opposite side edges, with one side edge mounted within, and bonded to the guard member. Further, the opposite side edge of the blade is received within, and detachably connected to, the groove of the handle. | ||||||
| 109 | Method and apparatus for repairing a wall covering | US11084419 | 2005-03-18 | US07300533B2 | 2007-11-27 | 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. In accordance with a method, 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. | ||||||

| 113 | Lamina cutter | US10830366 | 2004-04-22 | US20050235500A1 | 2005-10-27 | Anthony 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. | ||||||

The blade shank has a projecting end portion and the cutting edges are located on the projecting end portion and face rearwardly. One elongate guide member is located adjacent a free edge of the blade shank and the other guide member is located between the cutting edges. The handle and the guide members are preferably of a plastic material molded onto the metal blade shank. | ||||||
| 117 | Cutting device | US09964873 | 2001-09-28 | US20020035789A1 | 2002-03-28 | Moritz Muhlebach |
| A cutting device (1) for floor coverings, intended for cutting or starting a tear of seams, includes a base body (2) with at least one blade (3) that is mounted on the base body (2), and a contact edge (4), envisioned on the bottom side (5) of the base body (2), for an edge of a floor covering. A removable first plate (6) and a removable second plate (7) are attached in the front area of the base body (2), and the blade (3) can be arranged parallel to the contact edge (4) between the plates (6, 7). To provide a cutting device (1) that allows for the simple adjustment of the cutting width, at least one additional plate (8, 9, 10) is provided, allowing the blade (3) to be arranged, if necessary, between the second plate (7) and the additional plate (8) or between adjacent additional plates (8, 9, 10). | ||||||
| 118 | Cutter for fibrous compressible material | US56565 | 1998-04-07 | US5943780A | 1999-08-31 | Edward T. McIlhatten |
| The cutter of my invention is a unitary device that does not require a utility knife, only a blade. The cutter exposes twice the blade length of a conventional utility knife, i.e., approximately 2.2 inches. The blade can be extended into the insulation over 4 inches. The cutter has a blade guard (to keep fingers out of the way, etc.). The cutter also has a safety mechanism to guard against accidental exposure of the blade (you have to grip the tool by the handle to allow the blade to be exposed). The cutter also has an added leverage point directly in front of the grip to increase the amount of pressure you can exert on the insulation. This cutter compresses and cut in one continuous motion, i.e. the same motion does both compressing and cutting. | ||||||
| 119 | Carpet trimming tool | US768594 | 1996-12-18 | US5815929A | 1998-10-06 | Antonio M. Ojea |
| A carpet trimming tool precisely trims the edge of a carpet to fit against a carpet divider of the type having a linear channel upstanding from the edge of a thin flat flange fastened to the floor. The tool has a hand grip extending upward from a rigid base. Two elongate, straight parallel spaced apart legs extend downward from the base. A first leg has a foot adapted to slide on the carpet. The second leg has a foot adapted to slide in the channel. A carpet cutting blade is removably and adjustably mounted on the second leg so as to cut through the carpet a preset distance from the channel as tool is advanced, guided by the foot in the channel. | ||||||
| 120 | Carpet cutting knife guide | US287930 | 1994-08-09 | US5485676A | 1996-01-23 | Mark A. Terhorst |
| A carpet cutting knife guide for cutting overlapping adjacent edges of two pieces of carpet to be laid adjacently on a floor. The guide has two lateral members substantially parallel to each other and spaced from each other. A platform member extends from the first lateral member to the second lateral member and has an opening through which at least a blade of a carpet cutting knife member can pass to thereafter be positioned substantially at the floor. The opening has in conjunction therewith at least one friction fit means whereby a portion of the knife member can be releasably retained. The platform member is constructed of a flexible material such that exerting a force thereon causes the knife member to limitedly move substantially perpendicularly toward the floor. Wheels are provided for manually moving the guide over the overlapping edges of the carpet to be cut. Construction of the knife guide permits an operator to efficiently and precisely cut overlapping edges of two pieces of carpet simultaneously and then allows the resulting cut edges to fall into place adjacent each other in a clean and substantially identical seam-line pattern. | ||||||
