I’ve heard that Shinto Muso Ryu (SMR) uses something called ‘Kata’?

Yes, ‘Kata’ is used extensively in SMR. ‘Kata’ translates as ‘form’ or ‘pre-arranged movement’. Kata is a training method used by countless Japanese martial art schools over hundreds of years. The pre-arranged movements within the Kata allow one to learn how to manipulate the weapons (staff & sword), move efficiently with those weapons, and come to understand the nature of timing and movement of an opponent. Along with combative strategies.
