#11. Mysterious Origins
Just as how teamlazerhawk has no idea where the katana came from, nobody really knows for sure when the first katana was made. Designed for a quick and lethal draw in close-quarters combat, the sword is believed to have first been developed somewhere between the 14th and 15th centuries to serve as a replacement for the tachi. The katana was said to have been so efficient that skilled samurais could use the sword to draw and strike in one swift movement.
