At What Range?
Considering I know folk who can draw and instantly disable an opponent at close range (say, 1 second total elapsed time), I don't know about the gun vs sword contest. I know some folks who are damn good with a sword, and we're getting better.
I'm partial to spears and sticks. And good knives (with a 12-16" blade length). And spears. And my ASP. And my sword. And...
I am planning on having a "modern sword" made sometime this year. It will have a 10" handle, and a 16" curved blade. I believe this is the maximum size with any degree of practicality, and the perfect size for indoor use.
