  • Patent number: 4549725
    Abstract: A cutting guide for a blowtorch comprises a channel-shaped body member with front, back, and intermediate limbs, and a holder attachment for a blowtorch on its exterior. The back and intermediate limbs of the body member form a female slide member for receipt on a guide rail along which the body member is moved while cutting a metal plate or the like. The front limb is spaced forwardly of the intermediate limb to form a splatter shield protecting the female slide member against molten metal and slag formed while cutting, so as not to impede smooth sliding of the guide along the rail.
