Sabre Teeth are four weapons used by Kintaro in Mortal Kombat: Armageddon. They are similar to the Dragon Fangs used by Goro, a gauntlet-like grip with a singular long tooth-like claw extending past the hand. Concept art of the weapon can be found in the game's Krypt. Which shows that the weapon was supposed to have two claws instead of one.
Kintaro would be seen with this weapon in the New Timeline while leading his Shokan-Oni army in the Mortal Kombat X Comic Series.
