A tool for removing a rivet that connects a first article and a second article, the tool comprising: a frame comprising first and second arms (16, 20); an anvil disposed on the second arm of the frame, the anvil comprising a tube with an opening with an inner diameter (ID 50); a push pin (18; 118A-D) slidably engaged with the first arm of the frame, wherein the push pin (18; 118A-D) is further configured to engage with a hole in a tail end of the rivet in order to remove the rivet from the first article, wherein the push pin (18; 118A-D) is aligned coaxially with the anvil; a driver attached to the frame, wherein the driver is configured to move the push pin (18; 118A-D) in a linear direction towards the anvil in order to push the rivet out of engagement with the first article and such that the first and second articles (46, 48) become unattached, wherein the driver is configured to convert force applied to the tool into a force that is applied to the push pin (18; 118A-D) in order to move the push pin (18; 118A-D) in the linear direction relative to the anvil; and a lever connected to at least one of the anvil and the push pin (18; 118A-D), wherein the lever is configured to apply a mechanical advantage in order to cause the anvil to move relative to the push pin (18; 118A-D), wherein the lever comprises first and second handles (26, 28) connected to the driver; and characterised in that: the driver consists of a five pivot push pin and clevis assembly having a pivot, double clevis, first single clevis, second single clevis, links, and push pins; wherein the pivot is attached to an end of the push pin (18; 118A-D) slidably engaged with the first arm of the frame, is disposed in a portion of the driver, and is attached to ends of the first and second handles (26, 28). a frame comprising first and second arms (16, 20); an anvil disposed on the second arm of the frame, the anvil comprising a tube with an opening with an inner diameter (ID 50); a push pin (18; 118A-D) slidably engaged with the first arm of the frame, wherein the push pin (18; 118A-D) is further configured to engage with a hole in a tail end of the rivet in order to remove the rivet from the first article, wherein the push pin (18; 118A-D) is aligned coaxially with the anvil; a driver attached to the frame, wherein the driver is configured to move the push pin (18; 118A-D) in a linear direction towards the anvil in order to push the rivet out of engagement with the first article and such that the first and second articles (46, 48) become unattached, wherein the driver is configured to convert force applied to the tool into a force that is applied to the push pin (18; 118A-D) in order to move the push pin (18; 118A-D) in the linear direction relative to the anvil; and a lever connected to at least one of the anvil and the push pin (18; 118A-D), wherein the lever is configured to apply a mechanical advantage in order to cause the anvil to move relative to the push pin (18; 118A-D), wherein the lever comprises first and second handles (26, 28) connected to the driver; and characterised in that: the driver consists of a five pivot push pin and clevis assembly having a pivot, double clevis, first single clevis, second single clevis, links, and push pins; wherein the pivot is attached to an end of the push pin (18; 118A-D) slidably engaged with the first arm of the frame, is disposed in a portion of the driver, and is attached to ends of the first and second handles (26, 28).
