I Never Cared Much for Swords. Then I Had to Fight with One

If you want to try sword fighting there are a bunch of ways to do it.

HEMA people are generally very welcoming and probably slightly mad. quite expensive to get into, but great fun.

Fencing is more common, but start out with epee, foil is a big weird as you have right of way, its a training system and it shows, its harder to learn and not as fun. Sabre is for people who like shouting lots, more one hit wonder.

For the eastern styles:

A good Aikido class should start out with weapons, you wont be going full speed as even with wooden sticks, stuff gets dangerous pretty quick.

Korean sword work is going through somewhat of a renaissance, I don't know that much about it though.

If you're doing eastern style sword work, don't be tempted to get a metal sword, you'll never be able to train with it, and they are almost always poor quality. (unless you know what you're doing)

I enjoy Foil _because_ of right of way, it encourages blade work, movement and technique. Without right of way Epee is quite boring to watch because the fencers spend so much time trying to figure out how to hit their opponent without being hit themselves, but the lack of rules makes it easy to learn. Saber kind of has the opposite problem in that it's so fast it's hard to watch and there is very little extended blade work. To each their own though.
