Abstract

A modified reciprocating saw blade for use in association with a saw blade holder, shingles and nails, the apparatus comprises a blade member being formed in an elongated planar configuration with an inboard end, an outboard end and a central section, the inboard end being formed as a universal blade mount to permit coupling to a saw blade holder in an operative orientation, the central section having parallel linear upper and lower edges; and the outboard end of the blade member having an upper edge and a lower edge, the lower edge including a cutting region having a length of about one-third of the total length of the blade member, the cutting region including a plurality of cutting teeth, in an operative orientation the inboard end of the blade member being coupled to a saw blade holder, the configuration of the blade member permitting a user to cut nails which secure shingles without damaging adjacent shingles.

Claims

1. A modified reciprocating saw blade for use in association with a reciprocating saw blade holder, shingles and nails, the reciprocating saw blade comprising, in combination:

a blade member fabricated of steel and coated with "TEFLON", the blade member being 20 and 1/2 inches in length and formed in an elongated planar generally rectangular configuration with an inboard end, an outboard end and a central section, the inboard end of the blade member being formed as a universal blade mount, the universal blade mount including a projecting member and a circular aperture to permit coupling to a saw blade holder in an operative orientation, the central section having parallel linear upper and lower edges; and

the outboard end of the blade member having an upper edge and a lower edge, the lower edge including a cutting region having a length of one-third of the total length of the blade member, the cutting region being six inches in length and including about eighteen triangular shaped cutting teeth per inch, the outboard end having an outermost extent including rounded corners, in an operative orientation the inboard end of the blade member being coupled to a saw blade holder, the configuration of the blade member permitting a user to cut nails which secure shingles without damaging adjacent shingles.
