Cruiser Seiryūtō

The edge of Yokohama Prime's Cruiser Seiryūtō (クルーザー青龍刀 Kurūzā Seiryūtō, "Cruiser Green Dragon Blade") is without peer, for it can cleave the sea in two.

Notes

• The Cruiser Seiryūtō is part of Yokohama Prime's Chinese motif (Yokohama contains the largest Chinatown in Japan)—it is based on the legendary Green Dragon Crescent Blade (靑龍偃月刀 Qīnglóng Yǎn Yuè Dāo, or Seiryūengetsutō in Japanese). "Cruiser" is likely derived from Yokohama being a port for cruises.
