  • Attachment for a power hand saw
    Patent number: 4335512
    Abstract: A device is described for facilitating repeated cuts with a portable hand-held power saw. The device employs relatively slideable guides for guiding the saw through a cutting path. The saw is attached to one of the sliding guides in a manner such that the saw shoe lies very close to the work-piece surface and is offset from the relatively slideable guide, thereby avoiding substantial reduction in the depth of available cut of the saw.
