Abstract
Abstract A combined nut cutter and wrench tool including a body having an axis and a base from which a plurality of cutting blades extend with the cutting blades each having a first surface inclined relative to the axis and a second surface extending generally in the direction of the axis, the first and second surfaces converging to form cutting edges. A nut cutting tool including a body in the shape of a nut having an axis and an outer peripheral surface for reception in a socket of a socket wrench, a base on the body and a plurality of cutting blades extending outwardly from the base around the axis.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
130 words
A combined nut cutter and wrench tool comprising a body having an axis, a face on said body, a plurality of cutting blades on said body extending outwardly from said face in a generally axial direction, each of said blades having a first side which is inclined relative to said axis and a second side which extends in substantially the same direction as said axis, said first and second sides converging to form cutting edges extending in a generally radial direction relative to said axis and said second sides being oriented to bear against a nut after said blades have been driven into said nut without camming out of said nut when said tool is turned circumferentially against said nut, and an opening between said blades for receiving a bolt.
Claim 2
Dependent Claim
130 words
A combined nut cutter and wrench tool comprising a body having an axis, a face on said body, a plurality of cutting blades on said body extending outwardly from said face in a generally axial direction, each of said blades having a first side which is inclined relative to said axis and a second side which extends in substantially the same direction as said axis, said first and second sides converging to form cutting edges extending in a generally radial direction relative to said axis and said second sides being oriented to bear against a nut after said blades have been driven into said nut without camming out of said nut when said tool is turned circumferentially against said nut, and an opening between said blades for receiving a bolt.
Claim 3
Dependent Claim
34 words
A combined nut cutter and wrench tool as set forth in claim 1 including means on the opposite side of said body from said plurality of cutting blades for mounting on an impact handle.
Claim 4
Dependent Claim
25 words
A combined nut cutter and wrench tool as set forth in claim 1 wherein said body is a nut-like member for insertion into a socket.
Claim 5
Dependent Claim
24 words
A combined nut cutter and wrench tool as set forth in claim 1 wherein said plurality of blades are evenly spaced about said opening.
Claim 6
Dependent Claim
98 words
A tool for cutting a nut comprising a body in the shape of a nut having an axis and an outer peripheral surface for turning engagement by a wrench and a face extending substantially perpendicularly to said outer peripheral surface, and a plurality of cutting blades on said face extending generally radially on said body and in the general direction of said axis, each of said blades having a first side inclined relative to said axis and a second side extending generally in the direction of said axis, said first and second sides converging to form cutting edges.
Claim 7
Dependent Claim
98 words
A tool for cutting a nut comprising a body in the shape of a nut having an axis and an outer peripheral surface for turning engagement by a wrench and a face extending substantially perpendicularly to said outer peripheral surface, and a plurality of cutting blades on said face extending generally radially on said body and in the general direction of said axis, each of said blades having a first side inclined relative to said axis and a second side extending generally in the direction of said axis, said first and second sides converging to form cutting edges.
Claim 8
Dependent Claim
48 words
A tool for cutting a nut as set forth in claim 5 wherein each of said blades have a first side inclined relative to said axis and a second side extending generally in the direction of said axis, said first and second sides converging to form cutting edges.
Claim 9
Dependent Claim
110 words
In combination, a socket wrench and a tool for cutting a nut comprising a socket wrench having an opening of a predetermined peripheral configuration, a tool for cutting a nut comprising a body in the shape of a nut having an axis and an outer peripheral configuration for mating engagement with said opening, and a plurality of cutting blades on said body extending radially on said body and in the general direction of said axis, each of said blades have a first side inclined relative to said axis and a second side extending generally in the direction of said axis, said first and second sides converging to form cutting edges.
Claim 10
Dependent Claim
110 words
In combination, a socket wrench and a tool for cutting a nut comprising a socket wrench having an opening of a predetermined peripheral configuration, a tool for cutting a nut comprising a body in the shape of a nut having an axis and an outer peripheral configuration for mating engagement with said opening, and a plurality of cutting blades on said body extending radially on said body and in the general direction of said axis, each of said blades have a first side inclined relative to said axis and a second side extending generally in the direction of said axis, said first and second sides converging to form cutting edges.
Claim 11
Dependent Claim
17 words
The combination as set forth in claim 7 wherein said blades extend outwardly beyond said socket wrench.
Claim 12
Dependent Claim
16 words
The combination as set forth in claim 7 wherein said blades are located within said opening.
