So I'm having a bit of an issue I need to try and do.
I'm writing a story and I'm having some issues as to what kind of sword my main character should use. At first I chose a katana because I really love katanas, but then I realized that my main character has a very brutal and agressive style of sword fighting and that a longsword or claymore (he's really strong by the way) would fit his brute force sword style.
So which do you guys think I should chose?
Unless it's a magic/sci fi sword, consider what they'll be cutting and the style they'll need to use.
Claymores are for swinging/chopping/stabbing and rely on the point/weight/length of swing for max damage. They are meant for comparatively slower fighting techniques and are usually more durable. Because they are not curved, they're better used for a hack-style chop, rather than a draw-style chop when they contact the target. Their straightness/double edge gives slight advantages with stabbing.
Katanas are for slashing or lunging/stabbing and are designed to be used quickly and minimally. Typically katana are used to go for the throat or head of an opponent, or any other weak spot, since they aren't so effective when used with brute force against something armored, unlike a longsword. Unlike a straight sword, however, the blade curve gives extra cutting purchase when executing a slash against a vulnerable part.
If your character is a brute who likes to hammer shiz into submission, go with the longsword. Katana are not made for that kind of fighting.
