Abstract: A cable cutting tool includes a first arm having a first jaw member connected to a first handle member and a second arm having a second jaw member pivotally connected to a second handle member. The first and second arms are connected by a fastener and are pivotal with respect to one another about a longitudinal axis of the fastener. A tension element is mounted on the second jaw member and is positioned wholly outside of and out of contact with the second handle member. A take-up element is mounted for rotation on the second jaw member. A latching mechanism is mounted on the second jaw member and is configured to inhibit rotation of the take-up element in a first direction. The take-up element is uninhibited by the latching mechanism when rotating in a second direction. A chain extends over the take-up element and has a first end attached to the first arm and a second end attached to the tension element. The chain is positioned wholly outside of and out of contact with the second handle member.

Abstract: A knife sharpener (10) has pairs of overlapping, resiliently flexible fingers or strips (21-23, 31-33) to form opposed sharpening faces (27-29, 37-39) operable to engage at least one cutting edge (101) on a knife blade (102). The sharpening faces (27-29, 37-39) can have abrasive materials and/or surfaces (40-43) to generate the desired finish on the cutting edge(s) (101).

Abstract: The invention relates to a waterproof housing (1) of an apparatus, for example an electrically rechargeable shaving device, which housing (1) is provided with at least one opening (3a,3b) in a wall (1a), which opening is sealed off by means of a foil (4) permitting the equalization of a pressure difference between the inside of the housing and the outer atmosphere. In order to provide means for the equalization of a pressure difference suitable for all kinds of apparatuses, which means are not susceptible of contamination and at the same time are capable of equalizing pressure differences, the foil (4) is elastically deformable and provided with at least one incision (8,9) of which the cutting edges can yield owing to a pressure difference across said foil.

Abstract: Disclosed is a wienie roaster with prongs that may be folded back. The prongs are pivotly received by a head, and the head is attached at the end of a roaster stalk. The prong has a continuous curve as it enters the head which produces friction to hold the prongs at an adjustable angle away from or towards the roaster stalk. The bore in the head may have beveled, oval-shaped openings, so that the curved base of the prong notches into place in extended and folded back positions. The roaster may also have a tension shoe for applying and distributing pressure on the prongs and a notch in the prongs for receiving the tension shoe. A hole in the top of the head allows lubricant, such as oil or fat from cooking food, to enter the head and lubricate the base of the prong and the tension shoe. The lubrication hole may also be threaded to receive a set screw, which can provide additional pressure to hold the prong in place.

Abstract: A reciprocating saw includes a saw blade that is connected to a hand held driver for reciprocating the saw blade to perform a cut. A bit holder and a blade holder is used to provide connection between the saw blade and the handle of the hand held driver. The bit holder includes connecting mechanism for connecting the bit holder to the hand held driver. The blade holder provides a connection between the saw blade and the bit holder. The blade holder includes a holder body and a hex-shaped shank extending rearwardly from the holder body. The shank further includes a first holding mechanism for coupling the holder to the bit holder at the rear end and a second holding mechanism for coupling the saw blade to the holder at the forward end.

Abstract: A shearing tool has a fulcrum shaft, a first blade rigidly attached to the fulcrum shaft, a first element also rigidly attached to the fulcrum shaft and spaced apart on the shaft from the first blade, and a second blade contiguous with a second element, the second blade pivoted on the fulcrum shaft at one end of the blade, and between the attachment positions of the first blade and the first element such that relative rotation of the first and second elements causes relative rotation of the first and second blades producing a shearing action.

Abstract: This invention relates to folding knives, and more particularly folding knives which have locking mechanisms which engage the knife blade to prevent the inadvertent closing of the knife blade.

Abstract: An instrument for cutting hair comprises first and second members extending longitudinally in a direction generally parallel to a hinge axis 19 of a hinge that connects the two members. Each member has an arm and a leg. The legs have sockets in which tools are received. The arms comprise grip portions for grasping and actuating by a user's hand. During use, the actuation of the arms moves the legs in an arcuate path of a common circle about the hinge axis 19. The legs and the tools disposed in the sockets of the legs have straight features that remain parallel to each other and to the axis 19 of the hinge during movement along the arcuate path. The instrument has a closed pinching or clamping position in which the tools meet each other in abutting relation.

Abstract: A shock absorbing blade stop for a folding knife comprising; an elongated, cylinder shaped body, with o-ring grooves provided near its opposite ends. O-rings of a resilient material affixed to the o-ring grooves and the completed assembly located within the handle frames of a folding knife by means of location holes provided in the handle frames for that purpose. Location holes are of an inside diameter closely corresponding to the outside diameter of the mounted o-rings thereby producing a shock absorbing effect in response to the impact of a fast opening blade colliding against the blade stop. An enlarged center section of the blade stop is provided with an increased diameter slightly larger than the locating holes of the handle frames so as to capture the blade stop within the space between handle frames.

Abstract: A drill bit including a bit body having at least one roller cone rotatably coupled to the bit body with a plurality of milled teeth formed on the at least one roller cone is disclosed. At least one milled tooth is arranged so as to form a gage row milled tooth, and the gage row milled tooth includes hardfacing thereon. A cutting element insert is mounted in a gage face of the gage row milled tooth. A method of forming a drill bit structure, the method including machining at least one hole in a preselected location on a gage surface of at least one milled tooth, positioning a plug in the at least one hole, applying a hardfacing material to the at least one milled tooth, removing the plug from the at least one hole, and positioning a drilling insert in the at least one hole is also disclosed.

Abstract: A saw having an angle adjustable blade includes a handle and a blade. The handle includes a body and a ratchet structure. The ratchet structure includes a positioning member and a ratchet rod. Thus, the angle of the blade relative to the handle may be adjusted arbitrarily by rotating the blade relative to the handle, without having to change and adjust the angle of the handle, thereby facilitating the user operating the handle, and thereby preventing the user's wrist from being hurt.

Abstract: Blade clamps (26, 110) may reliably secure blades (22) to reciprocating power tools (10). The power tools may include a reciprocating drive shaft (24) partially extending from the tool housing (12). A first end of a rod (37, 112) may be attached to the drive shaft. A second end of the rod may include a blade slot (37a, 112a) defined to receive the blade so that the longitudinal axis of the blade aligns with a longitudinal, reciprocating axis of the drive shaft. An aperture (37b) may be defined substantially perpendicular to the first blade slot and may communicate with the blade slot. A sleeve (33, 115) may be rotatably mounted on the rod so as to pivot between an initial locking position and a blade replacement position. A cam surface (33c, 116) is defined on an inner surface of the sleeve. A stopper (33e, 116d) projects from the cam surface or the rod and defines the blade replacement position.
