Swords are categorized by two categories of Short and Long Swords. Long Swords, while less strong with handling, can be destructive with high damage against powerful enemies such as Goons and Demolishers. Short Swords, while contain greater handling, are just as great as the Long variants against enemies.
In real life, Swords have various purposes. In general, they are used as weapons for cutting and thrusting.
The European Longsword and Bastard Sword was used during the late Medieval and Renaissance periods and was characterized for having a cruciform hilt with a grip for two-handed usage and a straight double-edge blade.
The Katana was a traditional Japanese sword used by the Samurai of feudal Japan and was characterized by its curved, slender, single-edged blade with a circular or squared guard and long grip for two-handed usage.
The Khopesh was a Egyptian sickle-like sword used by the New Kingdom of Egypt and was evolved from battle axes.
Currently, there are no new variants for the Sword in The Following.
In real life, the Bastard Sword and the Long Sword in-game are actually the same weapon, however there is a difference between the two. The Bastard Sword has a shorter blade and can be used for one-handed use and with a shield, whereas the Long Sword is the opposite; it has a longer blade and is more for two-handed use.
Oddly, the weapon models in-game are about the same size as each other. This could've been a mistake or an oversight.
