A cutting tool comprising: a first lever having a first handle portion and a first cutting blade, wherein a gear portion is associated with the first cutting blade; a second lever having a second handle portion and a first cut-out portion; a second cutting blade pivotally coupled to the first lever at a first pivot point, and coupled to the second handle portion at a second pivot point; a gear lever pivotally coupled to the second cutting blade and the second handle portion at the second pivot point, wherein the gear lever is operatively coupled with the first gear portion, and wherein the gear lever includes a second cut-out portion; and an adjustment mechanism adapted to selectively allow rotation of the gear lever relative to the first gear portion to change mechanical advantage between the first lever and the second lever; the adjustment mechanism includes: at least one protrusion adapted to selectively abut with at least one of the first cut-out portion and the second cut-out portion to restrict further rotational movement of the first cut-out portion and the second cut-out portion respectively; and a selection mechanism adapted to selectively align the at least one protrusion with at least one of the first cut-out portion and the second cut-out portion, characterized in that: the adjustment mechanism is a toggle switch mechanism, wherein the toggle switch mechanism includes at least one spring which bias the at least one protrusion. a first lever having a first handle portion and a first cutting blade, wherein a gear portion is associated with the first cutting blade; a second lever having a second handle portion and a first cut-out portion; a second cutting blade pivotally coupled to the first lever at a first pivot point, and coupled to the second handle portion at a second pivot point; a gear lever pivotally coupled to the second cutting blade and the second handle portion at the second pivot point, wherein the gear lever is operatively coupled with the first gear portion, and wherein the gear lever includes a second cut-out portion; and an adjustment mechanism adapted to selectively allow rotation of the gear lever relative to the first gear portion to change mechanical advantage between the first lever and the second lever; the adjustment mechanism includes: at least one protrusion adapted to selectively abut with at least one of the first cut-out portion and the second cut-out portion to restrict further rotational movement of the first cut-out portion and the second cut-out portion respectively; and a selection mechanism adapted to selectively align the at least one protrusion with at least one of the first cut-out portion and the second cut-out portion, characterized in that: the adjustment mechanism is a toggle switch mechanism, wherein the toggle switch mechanism includes at least one spring which bias the at least one protrusion. at least one protrusion adapted to selectively abut with at least one of the first cut-out portion and the second cut-out portion to restrict further rotational movement of the first cut-out portion and the second cut-out portion respectively; and a selection mechanism adapted to selectively align the at least one protrusion with at least one of the first cut-out portion and the second cut-out portion, characterized in that: the adjustment mechanism is a toggle switch mechanism, wherein the toggle switch mechanism includes at least one spring which bias the at least one protrusion.
