  • Patent number: 6532614
    Abstract: A paint scraper includes a main body formed by a handle and a blade-supporting shank extending forwardly thereof. A nailset element is attached to the main body and is movable downwardly in response to being struck, so that a nail-impacting end of the nailset element can sink a protruding nail that is encountered while scraping paint from a wooden surface.

  • Patent number: 6487943
    Abstract: A torque-limiting screwdriver includes a shank disposed within a handgrip. A rear end of the shank engages the handgrip to enable an axial force to be transmitted from the handgrip to the shank. A release mechanism is provided to transmit rotation from the handgrip to the shank. The release mechanism is axially movable relative to both the handgrip and the shank and is spring biased into rotation transmitting relationship with the shank, whereby the rotation transmitting force applied to the shank is substantially independent of the axial force applied from the handgrip to the shank.

  • Patent number: 6393951
    Abstract: Pipe wrench with two shanks (14,15) each with a toothed jaw (11,12) at an angle to the shank, the shanks, connected at joint (13) and one shank translatable relative to the joint to adjust the distance between the jaws, with the tooth tips on each jaw located in a plane, and the height and pitch distance between teeth monotonously increasing from a small value for teeth (41,42) nearest to the shank up to a larger value for teeth (31,32) farthest from the shank, the increase being at least 25%.

  • Patent number: 6317989
    Abstract: A nose sprocket for the saw chain of a chain saw includes radially projecting teeth, each tooth having leading and trailing edges. Each of those edges includes a straight inner portion and an outer portion that deviates from a radius of the sprocket by a greater amount than the inner portion. The teeth are long enough to enter a space formed between side links of the saw chain.

  • Patent number: 6269722
    Abstract: A metal cutting bandsaw blade includes a strip and a recurring group of teeth projecting therefrom. The recurring group of teeth has a setting pattern and a height pattern. The setting pattern has at least three units selected from the following setting types: (a) unset teeth (b) teeth set to the right (c) teeth set to the left. The setting pattern includes at least one of each of the setting types. The height pattern has at least two selected from the following height types: (a) high teeth (b) low teeth. The height pattern includes at least one of each of the height types. The total number of teeth in the recurring group is the product of the number of setting units and the number of heights units. The number of setting units is incommensurable with the number of height units. The number of teeth set to the right in the recurring group is equal to the number of teeth set to the left. All of the set teeth in the group have substantially equal setting widths.

  • Patent number: 6257226
    Abstract: A metal saw for making long cuts through thick soft metals such as aluminum, copper or stainless steel, where friction, cutting force and scarring of the cut sides are minimized at a low production cost by grinding all teeth with a top edge inclined right or left 5 to 10 degrees, followed by setting some but not all teeth at a setting angle sized so that the top edges of the set teeth extend substantially at a right angle to a center plane of the body of the saw.

  • Patent number: 6253455
    Abstract: A handsaw includes a blade having a toothed cutting edge pivoted to a handle. The handle includes a frame and a tooth protecting element. The tooth protecting element is pivoted to the frame to be swung between a working position and a retracted position. Each of the frame and the tooth protecting element includes a gap, whereby when the tooth protecting element is in a retracted position, the gaps are aligned to receive the blade. When the blade is in a retracted state, a portion of the cutting edge is exposed to enable purchasers or users to know what type of cutting edge is provided on the blade without having to move the blade to a working position.
