Of all of the monsters and demons the Kane siblings have encountered, the switchblade demons have to be the most bizarre of them all. The demons are no laughing matter though, as their heads are dangerous weapons or other objects. An example of a switchblade demon is Bloodstained Blade, the captain of the Kanes' reed boat. He was okay with serving the siblings until Setne gave him orders to attack. The heads of switchblade demons aren't only for show, but the demons can easily use them when necessary as weapons.
