Qi'ra, a Crimson Dawn lieutenant, was proficient in this form of combat, having been trained by her employer Dryden Vos and used the form to take down Quay Tolsite of the Pyke Syndicate. The Elite Praetorian Guards of the First Order were also trained in Teräs Käsi, along with other martial arts.
Behind the scenesEdit
In the new Star Wars canon, Teräs Käsi was first mentioned in the 2015 mobile game Star Wars: Uprising. According to writer Gary Whitta, cut content from Rogue One: A Star Wars Story would have established that Saw Gerrera taught Teräs Käsi to Jyn Erso.
In the Finnish language, "teräs käsi" means "steel hand."
