A circular Sawblade, also known as a Buzz-Saw, is a weapon used by Kabal in Mortal Kombat 3 and its updates, as well as in Mortal Kombat (2011) and Mortal Kombat 11 as a special move.
Cyrax also uses a cybernetic version of the Sawblade in special moves and Fatalities, but unlike Kabal the Sawblade that Cyrax uses is mounted on his arm or comes out of his chest.
Triborg also uses Cyrax's Sawblades when shapeshifting into Cyrax in his LK-4D4 variation. It also appears in his Death Machine Fatality.
