Ferra's "Bloody Hand Claws" (A Kollector item in MK11)
Hand Claws are a pair of weapons used by Ferra in Mortal Kombat X. She will use it in any of Torr's variations with the exception of the Lackey variation, however she will use them during her and Torr's X-Ray regardless of the variation. She also uses them in both Fatalities. She continues to used them in her Kameo Fighter appearance in Mortal Kombat 1.
In Mortal Kombat: Legacy, Cyrax, after being turned into a Cyborg Ninja and sent to fight Hydro, would use hidden hand claws with forked blades to finish off Hydro with a Fatality by beheading him with said claws. These claws appear to replace his well-known Sawblades.
