The nangseon (Chinese: langxian, also calles "nangseonchang" in Korean) was a branched spear with many thorns attached to the branches. It is also called 'multi tip spear'. The blades could be dipped in poison. The nangseon was a perfect weapon for defense. It would be difficult for the opponent to get near the person holding the nangseon without getting touched by the thorns. The nangseon is already being mentioned in the 16th century martial arts manual Muyejebo.
