Abstract
A dual utility hacksaw blade includes additional mounting through holes. The first set of holes (outer) being the mounting holes for the use of the saw as a conventional hacksaw and the second set of holes being initially pilot holes to be enlarged by the end user when the second utility is desired. The method of the invention also recommends enlarging the first set of holes for mounting in the reciprocating saw as the second utility. Additionally, the blade may include construction facilitating breakage of the hacksaw at predetermined areas and in predetermined angles to provide the second utility. The hacksaw may also simply, and preferably, be cut or broken off for the second utility.
Claims15
A dual utility blade comprising:
- a) an elongated blade having two elongated edges one of which being adapted to cut an object and two longitudinal ends said blade including a structure adapted to facilitate shearing of said blade in predetermined locations and at predetermined angles;
- b) at least two apertures disposed in predetermined locations and being substantially longitudinally oriented on at least one of the two longitudinal ends of said blade and at least one aperture on the other of the two longitudinal ends of said blade.
A cutting device comprising:
- a) an elongated blade having two elongated edges one of which being adapted to cut an object;
- b) at least two apertures disposed in predetermined locations and being substantially longitudinally oriented on each of two longitudinal ends of said blade;
- c) a predetermined shearability structure adapted to facilitate shearing the blade at one or more of a plurality of predetermined locations and angles.
A method for providing dual utility for a conventional hacksaw blade comprising the steps of:
- a) providing a hacksaw blade having two first apertures one located on each end thereof;
- b) enlarging one of said first apertures;
- c) providing a second aperture in a predetermined position relative to said enlarged aperture;
- d) shearing said hacksaw blade at a desired angle and distance from said enlarged aperture.
A method for providing dual utility for a blade comprising the steps of:
- a) providing an elongated blade having two elongated edges one of which being adapted to cut an object and two longitudinal ends said blade having at least two apertures disposed in predetermined locations and being substantially longitudinally oriented on at least one of the two longitudinal ends of said blade and at least one aperture on the other of the two longitudinal ends of said blade;
- b) enlarging said two apertures;
- c) cutting said blade at a desired location and angle.
A method for providing dual utility for a conventional hacksaw blade comprising the steps of:
- a) providing a hacksaw blade having two first apertures one located on each end thereof and creating a second aperture substantially adjacent at least one of said first apertures;
- b) enlarging one of said first apertures adjacent said at least one second aperture;
- c) enlarging said at least one second aperture adjacent the enlarged said first aperture;
- d) shearing said hacksaw blade at a desired angle and distance from said enlarged first and second apertures.
