Abstract: A multifunctional filler tool is a combination of three different tools, the trowel covers and slides along the scraper between the idle and active positions, namely, the trowel and the scraper do not increase the width of the entire multifunctional filler tool so as to limit the size of the multifunctional filler tool. When in the active position, the trowel fully covers the scraper, while the scraper does not interfere with the operation of the trowel. When in the idle position, the trowel moves away from the scraper while still keeping abutting against the scraper, namely, the trowel won't protrude in the upward direction to stick out of the scraper; therefore, the trowel does not interfere with the gripping of the handle.

Abstract: A trimmer head for use with a plurality of lengths of flexible cutting line in a flexible line rotary trimmer having a plurality of line holders rotatably mounted thereon. Each line holder defines a pair of laterally spaced apertures in an upper surface thereof, a passageway extending longitudinally therethrough, terminating in an extended end thereof and communicating with the laterally spaced apertures. An interior guide surface extends along a curvilinear path from the spaced apertures to the passageway and a web extends between the apertures whereby end portions of lengths of cutting line can be extended into and through the spaced openings, along the guide surfaces into and through the passageway and outwardly therefrom, whereupon lengths of line extend about and are held against the web with portions of the line projecting from the passageways in the line holders for the cutting of vegetation.

Abstract: A knife has a pair of housing parts relatively shiftable between an open position and a closed position and a base on one of the housing parts forming a blade seat. A holding arm mounted on the base is movable relative thereto between a blade-holding position retaining a blade in the seat and a blade-change position freeing the blade so that in the blade-change position the blade can be switched. Interengaging formations on the other housing part and on the arm shift the holding arm from the blade-holding position into the blade-change position on movement of the housing parts from the closed position into the open position.

Abstract: An apparatus and method is provided for removing a retained member from a rotary head assembly configured for attachment to a rotary power source.

Abstract: A carpet knife having a housing, an active blade installed in the housing, and a blade clamping means having a clamping cover and a thumb screw. The housing has a thumb screw hole, a pin hole, at least one side guiding groove, and an active blade installation bar. The clamping cover has at least one side guiding bar having a wedge outer surface, and a rear eccentric guiding groove. The thumb screw has a head having an under surface and a shank formed on the under surface. The head has a pin formed on the under surface thereof which is able to enter and move in the rear eccentric guiding groove.

Abstract: In order to ergonomically induce relative sliding between a base and a cover member wherein the base is slidably mounted on the base and wherein the two members go to make a wide blade scraper body, a cam bearing wheel is mounted on the base and arranged to operatively engage a cam following feature which is formed on the cover. Rotation of the cam wheel which projects out of the sides of the handle portion with the thumb or the like, induces the cover to move relative to the base. As the relative movement proceeds a wide blade which is mounted at the leading edge of the scraper is released from a clamped constantly exposed position and is rendered changeable.

Abstract: 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.

Abstract: A utility knife for use with a flat blade having a pair of opposite faces has an elongated base part formed with an outwardly directed rear support surface, an outwardly directed front support surface separated longitudinally therefrom, and an inwardly directed intermediate surface between the support surfaces. The blade normally lies on the front support surface and projects longitudinally forward past the base part. An elongated cover part has an inwardly directed rear surface normally riding on the base-part rear support surface, an inwardly directed front surface normally pressing the blade inward against the base-part front support surface, and an outwardly directed intermediate surface. The cover part is displaceable longitudinally between one longitudinal end position with the intermediate surfaces transversely confronting each other and another longitudinal end position with the intermediate surfaces transversely out of alignment with each other.

Abstract: A holder for conventional rectangular cabinet scrapers having a body shaped like an open scroll, pivoting structures within each scroll-like end of the body to grasp a scraper blade along a substantial portion of its entire end, and a centrally located padded pressure plate adjustable with a thumb screw to apply pressure to one face of the cabinet scraper in order to bow it away from the body.

Abstract: A razor blade holder including a longitudinal slot for receiving a razor blade, first and second offset finger gripping elements and a clamping element provided within the slot for clamping a razor blade in the slot of the holder. The holder grips the blade with the point ready to use. Further, the blade is tightly clamped in the blade receiving slot so that the likelihood of movement of the blade relative to the holder minimized. In addition, the offset relation of the finger gripping elements enables the holder to be balanced to fit ergonomically between two or three fingers and thus fits relatively naturally within the hand and grip of the user.

Abstract: A fuzz remover wherein a blade having cutting edges at side edge portions thereof is held between a fuzz remover body having at both side edge portions thereof a plurality of teeth each of which projects therefrom in upwardly-inclined state and a bottom member attached to the lower surface of said fuzz remover body. The cutting edges of the blade project from the side edge portions of the fuzz remover body and the teeth project beyond the cutting edges. The outer ends of the teeth are connected by connectors.

Abstract: Animal implantates may be removed by a knife that permits the insertion and removal of blades without the manipulation of fasteners. Such a knife may be inexpensively manufactured by molding two relatively simple pieces that can be fitted together to hold a scalpel blade and to permit its incision to be guided and limited in depth. One piece of such a knife forms a handle having a first portion adapted to be gripped by hand and a blade-carrying second portion forming two ribs with a central slot. The second piece is a blade carrier having a first side surface adapted to engage an opening in a blade to hold the blade in fixed position on the blade carrier. The blade carrier has an upper bearing surface adapted to engage a rib of the first handle portion and a surface projecting upwardly centrally of the bearing surface and being adapted to engage the ribs of the first portion.

Abstract: Apparatus is provided herein for accepting a severed end of a saw blade into a clamping and squaring mechanism over a contoured die set. The die set is located immediately below a plunger slidably mounted through a supporting bridge so that force imparted therethrough to the die set causes the contoured shape of the die to be formed in the severed saw blade. The bridge is secured to a base which supports a portion of the die set and a movement limit or stop device is incorporated into the plunger to limit the stroke of the plunger.

Abstract: A grass edge trimmer includes a blade having at least one longitudinal cutting edge mounted on a handle by means of a pair of clamping portions. The clamping portions are located on opposite sides of the blade and engage the same along but spaced from said cutting edge so as to stiffen the blade. One of the clamping portions is removable from the handle and permits a worn cutting edge of the blade to be interchanged for a fresh cutting edge.
