REPLICA SWORD OF Ichigo Kurosaki from Bleach

Ichigo's zanpakut is named  Zangetsu.Unlike most Soul Reapers, who can seal their zanpakut after releasing it, Ichigo's zanpakut is always in its shikai form. Its sealed form is that of an ordinary zanpakut, but oversized as a result of Ichigo's uncontrolled spiritual pressure.
Zangetsu is portrayed as wise and calm in most matters, and fond of testing Ichigo in unusual ways, many of which have a purpose completely contrary to the stated goal. Zangetsu's special ability is the  Getsuga Tensh., a wave of spirit particles released from his blade's edge. Correspondent to the name, the wave is shaped like a crescent moon.
