For two years now, a pair of fencing aficionados have been running Golden Gate Knights, a service that "offers experienced instruction in saber choreography."
In other words, they teach you how to sword fight like you were in a Star Wars movie. One of the ones where people actually fight, too, not the old man shuffle from New Hope. So you can look less like this, and more like this.
These guys aren't fucking around. They've got a name for their method, which they call Novastar and Caine's Saber Combat System (NCSCS), and as you can see above, they know what they're doing.
Classes are held in San Francisco, are $10 per session and "No one is too old to begin the training." If you're nowhere near the Bay Area, they also sell DVDs.
