Abstract
An improved farrier nippers formed from two elongated members including handles, pivot regions and jaws. Blade members are formed separately from each elongated member and brazed into shelves of the jaws of the elongated members. Neck regions of the jaws of the elongated members each have an interior surface which is generally "V"-shaped. This facilitates removal of a portion of a work object which would otherwise obstruct a cut.
Claims18
A cutting tool, comprising:
- first and second elongated members,
- the first elongated member having a first handle at a proximal end, a first jaw at a distal end and having a distal tip formed into a first lower lip member, and a pivot region between the first handle and the first jaw;
- and
- the second elongated member having a second handle at a proximal end, a second jaw at a distal end and having a distal tip formed into a second lower lip member, and a pivot region between the second handle and the second jaw,
- the first elongated member pivotally attached to the second elongated member in the pivot region of each elongated member permitting the members to pivot with respect to each other in a plane of motion such that the cutting tool can be placed in an open position by pivoting the first handle away from the second handle and the cutting tool can be placed in a closed position, by pivoting the first handle towards the second handle, the cutting tool acting to cut as it closes;
- first and second blades respectively supported by the first and second lower lips at the respective distal tips of the first and second jaws, the first and second blades having respective opposed first and second edges for cutting a work object;
- and
- first and second braze joints, respectively attaching the first blade to the distal tip of the first jaw and the second blade to the distal tip of the second jaw;
- wherein the first jaw includes a first rear wall formed integrally therewith generally parallel to the first edge for supporting the first blade during a cut.
In a cutting tool of the type having first and second elongated members, the first elongated member having a first handle at a proximal end, a first jaw at a distal end thereof and having a distal tip, and a pivot region between the first handle and the first jaw, the second elongated member having a second handle at a proximal end, a second jaw at a distal end thereof and having a distal tip, and a pivot region between the second handle and the second jaw, the first elongated member pivotally attached to the second elongated member in the pivot region of each elongated member permitting the members to pivot with respect to each other in a first plane of motion such that the cutting tool can be placed in an open position by pivoting the first handle away from the second handle and the cutting tool can be placed in a closed position, by pivoting the first handle towards the second handle, the cutting tool acting to cut as it closes;
- and first and second blades respectively fixedly connected to the distal tips of the first and second jaws, the first and second blades having respective opposed edges for cutting a work object, the improvement in combination therewith comprising:
- a generally V-shaped cross section, taken along a second plane generally perpendicular to the first plane of motion, on at least one of the first and second jaws operable to displace a work object between the jaws to prevent obstruction of the cutting operation of the blades.
A method of fabricating a cutting tool, comprising the steps of:
- forming a first elongated member and a second elongated member, the first elongated member having a handle at a proximal end, a first jaw at a distal end and a pivot region between the handle and the first jaw, the second elongated member having a handle at a proximal end, a second jaw at a distal end and a pivot region between the handle and the second jaw;
- forming a first substantially planar blade member from a substantially planar sheet of material and a second substantially planar blade member from a second substantially planar sheet of material;
- brazing the first blade member onto a distal tip of the first jaw and the second blade member onto a distal tip of the second jaw so that the heat generated from the brazing process acts to harden edges of the first and second blade members;
- pivotally attaching the pivot region of the first elongated member to the pivot region of the second elongated member such that by pivoting the handle of the first elongated member towards the handle of the second elongated member the first blade member pivots towards the second blade member to allow a work object placed between the first and second blade members to be cut;
- wherein forming the first and second substantially planar blade members from substantially planar strips of rigid material reduces the amount of scrap material generated in forming the blade members.
