| 148 | SCRAPER HOLDER AND PROCESS FOR MAKING THE SAME | US15419164 | 2017-01-30 | US20180215032A1 | 2018-08-02 | Chung Tsai |
| A process for making a holder for a scraper includes the step of providing a metal sheet. Then, the metal sheet is cut into a semi-product. The semi-product includes a transverse strip including at least one slit to provide at least one flip, a middle longitudinal strip extending from the transverse strip, and two longitudinal strips extending from the transverse strip. Then, the semi-product is pressed to bend the flip from the transverse strip and turn the slit into apertures. The flip is used as a lower jaw and other portions of the transverse strip are used as upper jaws. | ||||||

| 152 | Two wheeled, hand driven, lamina material, shape cutter | US14275228 | 2014-05-12 | US09308655B2 | 2016-04-12 | Robert Anthony Peppett |
| A hand driven cutting device having a substantially pistol shaped body assembly, a knife blade clamped between a first substantially pistol shaped body part and a second substantially pistol shaped body part of the substantially pistol shaped body assembly, a pair of wheels with each wheel attached to the lower periphery of each front end portion via an axle and lifting and supporting element extending from the rear of the front end portion. The cutting action of a material work piece is facilitated by a stress induced on the material work piece at the point of contact between the material work piece and the cutting edge of the knife blade due to stretching of work piece against clamping pressure exerted by the pair of wheels on the material work piece when the cutting device is pushed forward by a user. | ||||||

| 154 | Variable pressure cutting devices | US12947161 | 2010-11-16 | US08701295B2 | 2014-04-22 | Joseph Clearman |
| An embodiment includes a cutting device having a blade; a device architecture configured to hold the blade that includes: a pressure body operable to remain rigid in response to a substrate pressing against a portion of the pressure body at a first pressure, and a portion of the pressure body operable to deform in response to the substrate pressing against a portion of the pressure body at a second pressure, and thereby provide variable resistance against the substrate; and, a cutter slot at a first device architecture end defined by the blade and the pressure body, the cutter slot configured to receive the substrate and operable to open rearwardly toward a second end as the pressure body deforms. | ||||||

| 156 | Scraper | US12613621 | 2009-11-06 | US20110094109A1 | 2011-04-28 | Lian-Zhen Chiu |
| A scraper includes a shell, a first controlling mechanism moveably installed within the shell for carrying a razor. The first controlling mechanism is moveable between a first position that the razor is exposed outside the shell and a second position that the razor is concealed in the shell. The scraper also includes a second controlling mechanism being independent of the first controlling mechanism and being utilized to selectively lock the razor therein. The razor is adapted to be removed from the first controlling mechanism when the second controlling mechanism is in an unlocked position. In addition, the scraper includes a compartment defined in the shell for storing unused razor(s). | ||||||
| 157 | Case knife with multiple position blade guards | US10301408 | 2002-11-21 | US07024772B1 | 2006-04-11 | Billy J. Shaver; Randy R. Busby; James S. Carter |
| A case knife (1, 101), generally consists of a pair of substantially symmetrical handle shells (13, 112). A single edge razor blade B is removably supported in one end of the handle formed by these handle shells. Each handle shell includes two moving parts—a guard (10, 110) and a thumb or finger operable button (5, 105). Each such guard, when paired with a substantially identical guard of the other handle half shell, flanks the otherwise protruding sharp edge of the razor blade. Each guard can move independently to expose a protruding corner of the razor blade. The operable button is mounted on an axle or lug (14, 103) that passes from the inside of a handle shell, through to its outside surface. This axle is in turn fixed to a cam follower (20, 120) mounted on the inside of each shell. | ||||||
| 158 | Single edge razor blade holder | US10752392 | 2004-01-06 | US20040200080A1 | 2004-10-14 | Aaron P. Lauri |
| A razor blade holder includes a slotted housing for removably retaining a razor blade therewithin. The housing accommodates at least one magnet. The housing is used conjointly with a keeper having a magnet affixed thereto. The housing and keeper, in use, sandwich a portion of a garment therebetween to provide easy and safe access to a razor blade. The magnets used herein are preferably neodymium magnets. Also, the present invention is particularly adapted for use with a single edge razor. | ||||||
| 159 | Scraping tool with replaceable blade and controlled quick-release clamp | US907292 | 1997-08-06 | US5996231A | 1999-12-07 | David E. Roche; Mark E. Baerenrodt; David H. Mallalieu; Mark T. Panaccione |
| A scraping tool employing a sharp-edged blade such as a wallpaper shaving blade, utility or razor blade; comprising an integral body and handle, a controllable quick-release blade clamp and latching level to lock and unlock the clamp for access to the blade. Both the clamp and lever are pivotably connected to the body/handle component using the "snap-fit" technique. The tool includes an integral resilient member for maintaining the clamp closed whenever the tool is unlocked, such that the blade will be retained at all times, until the clamp is purposefully actuated by the user for installation or removal of the blade. | ||||||
| 160 | Safety razor blade tool | US954692 | 1997-10-20 | US5943781A | 1999-08-31 | Jisu Kim |
| A safety razor blade tool comprises a substantially rectangular, single-edged safety razor blade having a cutting edge and an opposing non-cutting edge and a thermoplastic protective cover fixedly attached to the non-cutting edge. The protective cover is substantially coextensive with the length of the non-cutting edge of the blade and has a resilient, slip-resistant surface. The protective cover comprises two substantially identical, complimentary cover parts. Each cover part comprises an injection-molded substantially rigid inner layer of thermoplastic material and a rubberized outer layer covering the rigid inner layer. The outer layer comprises a compatible, injection-molded thermoplastic rubber. | ||||||
