At the risk of outting myself, I was in the SCA briefly when I was in college. I think, if someone wants to write about sword fighting the European way they could do worse than contact their local SCA chapter and see if someone would teach them the fundamentals. Sure, SCA swords are made of wood (rattan, actually, because it doesn't slpinter) but during the middle ages in Europe, swords weren't necessarily all that sharp, and I was astonished to discover that combat consisted of beating at each other with really heavy metal clubs that had just enough edge on them to make them nasty.

The experience of wearing armor on a summer day will also change your life and make you grateful for the invention of deodorant.

I do most of my learning via the teacher/student route myself, rather than books or videos. I can, however, strongly recommend:
Sai, Karate Weapon of Self-Defense by Fumio Dumura.
Kubotan Keychain - Instrument of Attitude Adjustment by Takayuki Kubota - the kubotan is a newer weapon devised in the 1970s, but many of the techniques will also work with a baton
Tonfa, Karate Weapon of Self-Defense by Fumio Demura - the handled night stick used by many police (I can't recall its numeric designation) is essentially a single tonfa, so this may be a useful weapon to have some familiarity with in cyberpunk, modern sf/f, dystopia sf/f, and that sort of thing.

Cool.

Yeah, some SCA folks clearly know their stuff. Some day I’d like to check out the Association for Renaissance Martial Arts, too — even if they do have a pretty big chip on their collective shoulder . . .

Poking through some files on my computer, I came across one on various reference books on sharp pointy things and the usage of same.

"The Western Way of War: Infantry Battle In Ancient Greece," by Victor Davis Hanson.

"The Way of the Sword," by Richard Burton.

"A Glossary of the Construction, Decoration and Use of Arms and Armor in All Countries and in All Times Together With Some Closely Related Subjects," by George Cameron Stone.

"Schools and masters of fence, from the Middle Ages to the end of the eighteenth century," by Egerton Castle.

"The Book of the Crossbow," by Ralph Payne-Gallwey.

I cannot speak to all of these, but I remember the Hanson book being rather interesting reading.
