In one embodiment, a folding knife comprises a handle and a knife blade. The knife blade comprises a tang pivotably connected to the handle, and the blade is operable to pivot relative to the handle about a pivot axis extending through the tang between a closed position and an open position. The tang comprises an enlarged tang portion that extends outwardly from the handle when the blade is in the closed position, and the enlarged tang portion comprises a cutting portion. ## Claims ### Claim 1 A folding knife, comprising: a handle; and a knife blade comprising a tang pivotably connected to the handle, the blade being operable to pivot relative to the handle about a pivot axis extending through the tang between a closed position and an open position, the tang comprising an enlarged tang portion that extends through the handle and outwardly from the handle when the blade is in the closed position; wherein the enlarged tang portion comprises a cutting portion. ### Claim 2 (depends on 1) The folding knife of claim 1, wherein the enlarged tang portion extends from the tang on the same side of the blade as a cutting edge of the blade. ### Claim 3 (depends on 2) The folding knife of claim 2, wherein the enlarged tang portion extends from the tang on the same side of the blade as an opposing edge opposite the cutting edge. ### Claim 4 (depends on 1) The folding knife of claim 1, wherein the tang comprises a first enlarged tang portion on the same side of the blade as a cutting portion of the blade and a second enlarged tang portion on the same side of the blade as an opposing edge opposite the cutting edge. ### Claim 5 (depends on 4) The folding knife of claim 4, wherein the first and second enlarged tang portions each comprise a cutting portion. ### Claim 6 A folding knife, comprising: a handle; and a knife blade pivotably connected to the handle and comprising a cutting edge, an opposing edge opposite the cutting edge, and a tang, the blade being operable to pivot relative to the handle about a pivot axis extending through the tang between a closed position and an open position, the tang comprising an enlarged tang portion that extends outwardly from the handle when the blade is in the closed position; wherein the enlarged tang portion comprises a cutting portion, the cutting portion having first and second scalloped portions formed in opposing sides of the enlarged tang portion. ### Claim 7 (depends on 6) The folding knife of claim 6, wherein the first scalloped portion comprises a first depth to which the first scalloped portion extends into the large tang portion. ### Claim 8 (depends on 7) The folding knife of claim 7, wherein the second scalloped portion comprises a second depth to which the second scalloped portion extends into the large tang portion. ### Claim 9 (depends on 8) The folding knife of claim 8, wherein the first and second scalloped portions converge with each other at a common front edge. ### Claim 10 (depends on 9) The folding knife of claim 9, wherein the first depth is greater than the second depth. ### Claim 11 (depends on 9) The folding knife of claim 9, wherein the first depth is equal to the second depth. ### Claim 12 (depends on 9) The folding knife of claim 9, wherein the first and second depths increase moving in a direction along a length of each scalloped portion from a back edge of each scalloped portion toward the common front edge. ### Claim 13 (depends on 9) The folding knife of claim 9, wherein the cutting portion comprises a front receiving slot defined by a lip portion of the enlarged tang portion that extends beyond the common front edge of the cutting portion. ### Claim 14 (depends on 13) The folding knife of claim 13, wherein the front receiving slot is configured to receive a piece of material to be cut. ### Claim 15 (depends on 6) The folding knife of claim 6, wherein the folding knife further comprises a window breaker. ### Claim 16 (depends on 15) The folding knife of claim 15, wherein the window breaker is mounted on an end of the handle opposite the tang of the blade. ### Claim 17 (depends on 6) The folding knife of claim 6, wherein the cutting portion comprises a seat belt cutter. ### Claim 18 A method of cutting a material, comprising: holding a folding knife having a blade, a handle, and a tang, the tang comprising an enlarged tang portion having a cutting portion, the cutting portion comprising first and second scalloped portions formed in opposing sides of the enlarged tang portion, the blade being in a closed position such that a cutting edge of the blade is in the handle and the cutting portion of the enlarged tang portion extends from the handle; cutting the material with the cutting portion of the tang. ### Claim 19 (depends on 18) The method of claim 18, wherein cutting the material comprises cutting a seatbelt.
