SWORDS
The weapon of choice
for my favourite fight scene in the Whole of Buffy - ever.
Swords have been around since the bronze age in various forms. Long, pointy
and very sharp, most people think of 'Higlander' when you mention swords. (Did
you know there is a blacksmith in Hollywood who is employed solely to make swords
for the different Hollywood films and TV series?).
HOW TO USE A SWORD
Watch 'Highlander' (that, apparently, is a very good technique to use). Swing and try to hit bad guys with the sharp edge. There's probably more to it than that, but having never used one (when would I get the chance?) I can't really tell you what to do.
OTHER USES FOR A SWORD
Use it to rid the world of immortals (if you are an immortal yourself).
Use it to have rather dangerous lightsaber fights.
