The second jaw includes a second ear with a third ear bore that aligns in between a first ear bore and to a second ear bore of the first ear when the second ear is coupled in the slot of the first ear. The cutting head further includes a spring-biased flange coupled to a blade mounted to the first jaw and a retained coupled at a fixed position to a blade mounted to the second jaw. The retainer is configured to receive the flange during a cutting action such that the flange prevents the blades from shifting out of alignment during the cutting action. ## Claims ### Claim 1 A cutting head for a hydraulic power tool, the cutting head comprising: a hollow pin, a first jaw disposed for rotation about an axis defined by the hollow pin, the first jaw comprising a first blade mounting surface having a first pair of screw bores configured to receive a first pair of blade mount screws and further comprising a first ear, wherein the first ear includes a first ear bore and a second ear bore for receiving the hollow pin and a slot for receiving a second ear; a second jaw disposed for rotation about the axis defined by the hollow pin, the second jaw comprising a second blade mounting surface having a second pair of screw bores configured to receive a second pair of blade mount screws and further comprising the second ear having a third ear bore such that the third ear bore aligns in between the first ear bore and the second ear bore of the first ear when the second ear is coupled in the slot of the first ear; a first blade mounted to the first blade mounting surface of the first jaw by the first pair of blade mount screws; a second blade mounted to the second blade mounting surface of the second jaw by the second pair of blade mount screws; a flange configured as a separate component from the first blade and coupled to and extending from the first blade; and a retainer coupled to the second blade, the retainer having an inner groove configured to receive the flange prior to and during a cutting action to resist movement of the first jaw or the second jaw out of alignment during the cutting action, and the inner groove configured to receive the first blade. ### Claim 2 (depends on 1) The cutting head of claim 1, wherein the flange is pivotably coupled to the first blade. ### Claim 3 (depends on 1) The cutting head of claim 1, wherein the flange is spring-biased toward the retainer in an extended configuration. ### Claim 4 (depends on 1) The cutting head of claim 1, wherein the retainer is mounted to the second blade at a fixed position. ### Claim 5 (depends on 4) The cutting head of claim 4, wherein the first jaw and the second jaw rotate about the axis defined by the hollow pin causing the retainer to receive the flange such that the flange prevents the first blade and the second blade from shifting out of alignment during the cutting action. ### Claim 6 (depends on 1) The cutting head of claim 1, wherein the second ear comprises the third ear bore for receiving a pivot pin positioned through the hollow pin. ### Claim 7 (depends on 6) The cutting head of claim 6, further comprising: a pivot pin that attaches the first jaw to the second jaw. ### Claim 8 (depends on 1) The cutting head of claim 1, wherein the second blade is disposed within the inner groove. ### Claim 9 (depends on 1) The cutting head of claim 1, wherein the flange includes first and second detent plungers. ### Claim 10 A power tool comprising: a cutting head comprising: a hollow pin, a first jaw disposed for rotation about an axis defined by the hollow pin, the first jaw comprising a first blade mounting surface having a first pair of screw bores configured to receive a first pair of blade mount screws and further comprising a first ear, wherein the first ear includes a first ear bore and a second ear bore for receiving the hollow pin and a slot for receiving a second ear; a second jaw disposed for rotation about the axis defined by the hollow pin, the second jaw comprising a second blade mounting surface having a second pair of screw bores configured to receive a second pair of blade mount screws and further comprising the second ear having a third ear bore such that the third ear bore aligns in between the first ear bore and the second ear bore of the first ear when the second ear is coupled in the slot of the first ear; a first blade mounted to the first blade mounting surface of the first jaw by the first pair of blade mount screws; a second blade mounted to the second blade mounting surface of the second jaw by the second pair of blade mount screws; a flange pivotably coupled to and extending from the first blade; and a retainer coupled to the second blade, the retainer having an inner groove dimensioned to receive the flange and the first blade, the inner groove configured to receive the flange prior to and during a cutting action to resist movement of the first jaw or the second jaw out of alignment during the cutting action. ### Claim 11 (depends on 10) The power tool of claim 10, wherein the flange is spring-biased toward the second blade in an extended configuration. ### Claim 12 (depends on 10) The power tool of claim 10, wherein the retainer is mounted to the second blade at a fixed position. ### Claim 13 (depends on 12) The power tool of claim 12, wherein the first jaw and the second jaw rotate about the axis defined by the hollow pin causing the retainer to receive the flange such that the flange prevents the first blade and the second blade from shifting out of alignment during the cutting action. ### Claim 14 (depends on 10) The power tool of claim 10, wherein the second ear comprises the third ear bore for receiving a pivot pin positioned through the hollow pin. ### Claim 15 (depends on 14) The power tool of claim 14, further comprising: a pivot pin that attaches the first jaw to the second jaw. ### Claim 16 (depends on 10) The power tool of claim 10, wherein the flange is moveable between an extended position and an open position, wherein in the extended position, the flange extends into the retainer during a cutting action and in the open position, the flange does not extend into the retainer.
