The core comprises a first position in which the core is disposed in alignment with the shear plane, and a second position in which the core is disposed out of alignment with the shear plane. The shear component can be included in a downhole tool to maintain the downhole tool in the run-in or initial position until being compromised by a stimulus. ## Claims ### Claim 1 A shear component for use in a downhole tool, the shear component comprising: a body having a first end, a second end, an outer wall surface, an inner wall surface defining a cavity, and a shear plane; and a core disposed within the cavity and in sliding engagement with the inner wall surface of the body, the core comprising a first position in which the core is disposed across the shear plane, and a second position in which the core is not disposed across the shear plane. ### Claim 2 (depends on 1) The shear component of claim 1, wherein the core is retained in the first position by a corrodible member disposed at least partially within the cavity, at least a portion of the corrodible member being in fluid communication with the opening in the first end. ### Claim 3 (depends on 2) The shear component of claim 2, wherein the first end includes an opening and the second end is closed. ### Claim 4 (depends on 3) The shear component of claim 3, wherein the corrodible member is retained at least partially within the cavity by a retaining ring. ### Claim 5 (depends on 1) The shear component of claim 1, further comprising an actuator for moving the core from the first position to the second position. ### Claim 6 (depends on 5) The shear component of claim 5, wherein the actuator comprises a compressible member. ### Claim 7 (depends on 6) The shear component of claim 6, wherein the compressible member comprises a spring having a compressed position when the core is in the first position and an expanded position when the core is in the second position. ### Claim 8 (depends on 5) The shear component of claim 5, wherein the actuator comprises a compressible material having a compressed position when the core is in the first position and an expanded position when the core is in the second position. ### Claim 9 (depends on 1) The shear component of claim 1, wherein the first end includes a first opening, the second end includes a second opening, and the core is retained in the first position by a retaining ring acting on a first end of the core and a compressible member acting on a second end of the core, the retaining ring preventing the core from moving toward the first end and the compressible member moving from an expanded position to a compressed position when the core is moved from the first position to the second position. ### Claim 10 (depends on 9) The shear component of claim 9, wherein the compressible member comprises a spring. ### Claim 11 (depends on 1) The shear component of claim 1, wherein the first end includes a first opening, the second end includes a second opening, and the core is retained in the first position by a retaining ring acting on a first end of the core and a shear ring, the retaining ring preventing the core from moving toward the first end and the shear ring preventing movement of the core toward the second end until the shear ring is compromised. ### Claim 12 (depends on 1) The shear component of claim 1, wherein the outer wall surface of the body includes a groove disposed along the shear plane. ### Claim 13 A downhole tool comprising: a first component; a second component, the second component being releasably secured to the first component by a shear component, the shear component having a body having a first end, a second end, an outer wall surface, an inner wall surface defining a cavity, and a shear plane and a core disposed within the cavity and in sliding engagement with the inner wall surface of the body, the core comprising a first position in which the core is disposed across the shear plane, and a second position in which the core is not disposed across the shear plane. ### Claim 14 (depends on 13) The downhole tool of claim 13, wherein the first end of the shear component includes an opening and the second end is closed, and the core is retained in the first position by a corrodible member disposed at least partially within the cavity, at least a portion of the corrodible member being in fluid communication with the opening in the first end. ### Claim 15 (depends on 13) The downhole tool of claim 13, wherein the first end includes a first opening, the second end includes a second opening, and the core is retained in the first position by a retaining ring acting on a first end of the core and a compressible member acting on a second end of the core, the retaining ring preventing the core from moving toward the first end and the compressible member moving from an expanded position to a compressed position when the core is moved from the first position to the second position. ### Claim 16 (depends on 13) The downhole tool of claim 13, wherein the first end includes a first opening, the second end includes a second opening, and the core is retained in the first position by a retaining ring acting on a first end of the core and a shear ring, the retaining ring preventing the core from moving toward the first end and the shear ring preventing movement of the core toward the second end until the shear ring is compromised. ### Claim 17 A method of actuating a downhole tool, the method comprising the steps of: (a) applying a first stimulus to a downhole tool causing movement of a core disposed in a cavity of a shear component to move from a first position to a second position, the core being disposed in alignment with a shear plane of the shear component when in the first position and the core being disposed out of alignment with the shear plane when in the second position; (b) compromising the shear component causing a first component of the downhole tool to be able to move relative to a second component of the downhole tool; (c) applying a second stimulus to the downhole tool to the first component causing the first component to move from an initial position to an actuated position to cause actuation of the downhole tool. ### Claim 18 (depends on 17) The method of claim 17, wherein the first stimulus is a corrosive material. ### Claim 19 (depends on 17) The method of claim 17, wherein during step (a), a compressible member facilitates movement of the core from the first position to the second position. ### Claim 20 (depends on 17) The method of claim 17, wherein the first stimulus is a fluid pressure. ### Claim 21 (depends on 20) The method of claim 20, wherein during step (a), a compressible member moves from an expanded position to a compressed position due to the fluid pressure acting on the core. ### Claim 22 (depends on 17) The method of claim 17, wherein step (b) and step (c) are performed simultaneously.
