Abstract:
A cutting tool (1) primarily intended for cutting plastic pipe (2), said cutting tool including first and second elongated members (3,5) connected to each other for pivotal movement about a pivotal axis (9) between the respective ends (3â€², 3â€³ and 5â€²,5â€³) of the first and second elongated members,said first elongated member (3) having a curved anvil (13) adjacent one end (3â€²) thereof and a handle portion (3â€³) adjacent the other end, said second elongated member (5) having knife blade (11) adjacent one end (5â€²) thereof and a handle portion (5â€³) adjacent the other end, said knife blade (11) having a cutting edge (11â€²) and said curved anvil (13) of said first elongated member (3) having a slot (13â€²) therein for receiving the cutting edge (11â€²) of said knife blade (11) when said elongated members (3,5) are closed together by squeezing said handle portions (3â€³,5â€³) together, said second elongated member (5) being received in a central aperture (21) through said first elongated member (3), said aperture (21) being defined in part by an edge portion (25) on said first elongated member (3), said cutting tool (1) further including a leaf spring (15) to bias said handle portions (3â€³,5â€³) of said elongated members (3,5) apart to open and separate said knife blade (11) and curved anvil (13) to receive the pipe (2) therebetween, said leaf spring (15) having first and second end portions (15â€²,15â€³), said first end portion (15â€²) having a substantially curved lip (29) and a section (27) adjacent said curved lip (29), said curved lip (29) having an edge (31) and being dimensioned to clip over the edge portion (25) of the aperture (21) wherein said curved lip (29) is flexed to pinch the edge portion (25) between the edge (31) of the curved lip (29) and said adjacent section (27) of the first end portion (15â€²) of the leaf spring (15) to retain said leaf spring (15) on said edge portion (25) of the aperture (21) with the second end portion (15â€³) of said leaf spring (15) extending to abut against the handle portion (5â€³) of the second elongated member (5) to bias the handle portions (3â€³,5â€³) of the first and second elongated members (3,5) apart.
