According to one aspect, a conduit cutting tool includes a pivot pin defining a pivot axis, a pair of elongated members coupled with one another by the pivot pin, and wherein the elongated members individually comprise a jaw at a first end and a handle at a second end and interior portions of the jaws comprise cutting blades which are configured to cut the conduit, wherein the jaws are spaced apart from one another by a first distance when the conduit cutting tool is in an open configuration to receive a conduit to be cut between the jaws and one of the elongated members is configured to move with respect to an other of the elongated members as a result of an application of an input force to the handles to provide the tool in a closed configuration wherein the jaws are spaced apart from one another by a second distance less than the first distance to cut the conduit, and wherein the movement of the one elongated member rotates the jaw of the one elongated member towards the jaw of the other elongated member and moves the jaw of the one elongated member in a substantially linear direction towards the jaw of the other elongated member. ## Claims ### Claim 1 A conduit cutting tool comprising: a pivot pin defining a pivot axis; a pair of elongated members coupled with one another by the pivot pin, and wherein the elongated members individually comprise a jaw at a first end and a handle at a second end and interior portions of the jaws comprise cutting blades which are configured to cut a conduit; wherein the jaws are spaced apart from one another by a first distance when the conduit cutting tool is in an open configuration to receive the conduit to be cut between the jaws and one of the elongated members is configured to move with respect to an other of the elongated members as a result of an application of an input force to at least one of the handles to provide the tool in a closed configuration wherein the jaws are spaced apart from one another by a second distance less than the first distance to cut the conduit; and wherein the movement of the one elongated member rotates the jaw of the one elongated member towards the jaw of the other elongated member and moves the jaw of the one elongated member in a substantially linear direction towards the jaw of the other elongated member. ### Claim 2 (depends on 1) The tool of claim 1 wherein the other elongate member comprises a slot and the pivot pin moves within the slot during the movement of the one elongated member with respect to the other elongated member. ### Claim 3 (depends on 2) The tool of claim 2 wherein the slot defines the substantially linear movement of the jaw of the one elongated member towards the jaw of the other elongated member. ### Claim 4 (depends on 3) The tool of claim 3 wherein the jaw of the one elongated member rotates about the pivot pin during the movement of the one elongated member with respect to the other elongated member. ### Claim 5 (depends on 2) The tool of claim 2 further comprising a linkage coupled with the handles of the elongated members and which is configured to cause the movement of the pivot pin within the slot during the movement of the one elongated member with respect to the other elongated member. ### Claim 6 (depends on 5) The tool of claim 5 wherein the linkage is coupled with and configured to rotate about another pivot pin which is coupled with the one elongated member during the movement of the one elongated member with respect to the other elongated member. ### Claim 7 (depends on 6) The tool of claim 6 further comprising a spring configured to bias the handles apart from one another to provide the conduit cutting tool in the open configuration in the absence of the input force. ### Claim 8 (depends on 8) The tool of claim 8 wherein a first end of the linkage is coupled with the other elongated member and the spring is coupled with a second end of the linkage which is opposite to the first end of the linkage. ### Claim 9 (depends on 8) The tool of claim 8 wherein the another pivot pin is between the first and second ends of the linkage. ### Claim 10 (depends on 1) The tool of claim 1 wherein individual ones of the jaws include at least three substantially linear segments. ### Claim 11 (depends on 1) The tool of claim 1 further comprising a bias system configured to bias the handles apart from one another to provide the conduit cutting tool in the open configuration in the absence of the input force. ### Claim 12 (depends on 1) The tool of claim 1 wherein the cutting blades extend a distance outwardly from surfaces of the jaws which corresponds to a gauge of the conduit. ### Claim 13 A conduit cutting tool comprising: a pivot pin defining a pivot axis; a pair of elongated members coupled with one another by the pivot pin, and wherein the elongated members individually comprise a jaw at a first end and a handle at a second end and interior portions of the jaws include cutting blades which are configured to cut the conduit; wherein a first of the elongated members is configured to rotate about the pivot axis as a result of an application of an input force to at least one of the handles; wherein a second of the elongated members comprises a slot configured to receive the pivot pin; a linkage coupled with the handles of the elongated members and configured to cause movement of the pivot pin within the slot as a result of the application of the input force to the at least one handle; and wherein the application of the input force to the at least one handle changes the conduit cutting tool from an open configuration wherein a conduit to be cut is received between the jaws to a closed configuration to cut the conduit. ### Claim 14 (depends on 13) The tool of claim 13 wherein the application of the input force to the at least one handle rotates the jaw of the first elongated member towards the jaw of the second elongated member and moves the jaw of the first elongated member in a substantially linear direction towards the jaw of the second elongated member. ### Claim 15 (depends on 13) The tool of claim 13 wherein the slot defines substantially linear movement of the jaws with respect to one another. ### Claim 16 (depends on 13) The tool of claim 13 further comprising a bias system configured to bias the handles apart from one another to provide the conduit cutting tool in the open configuration in the absence of the input force. ### Claim 17 (depends on 16) The tool of claim 16 wherein the bias system comprises a spring coupled with the linkage and the first elongated member. ### Claim 18 A conduit cutting tool operational method comprising: providing a plurality of jaws of a conduit cutting tool about a conduit to be cut, the interior surfaces of the jaws comprising cutting blades configured to cut the conduit; applying a force to a plurality of handles coupled with the jaws to move the handles towards one another; as a result of the applying, moving one of the jaws in a substantially linear direction towards an other of the jaws and rotating the one jaw towards the other jaw; and during the applying, moving the conduit cutting tool back and forth around a circumference of the conduit to cut the conduit using the cutting blades. ### Claim 19 (depends on 18) The method of claim 18 further comprising selecting the cutting blades individually having a cutting depth which is the same as a thickness of a wall of the conduit. ### Claim 20 (depends on 18) The method of claim 18 wherein the conduit cutting tool comprises a plurality of elongated members coupled with a pivot pin, and the moving one jaw comprises moving the pivot pin within the slot and the rotating the one jaw comprises rotating about the pivot point.
