monohoshizao (fate)
The sword carried by Sasaki Kojirou from Fate, based on the sword used by the historical Sasaki Kojirou, who is said to have died in a duel with Miyamoto Musashi in 1612. It boasts an unusually long and heavy blade for a Japanese sword, and it takes an extraordinary man to even draw it from its scabbard, much less wield it in combat.
