Gatack Double Calibur (ガタックダブルカリバー Gatakku Daburu Karibā): Only available in Gatack's Rider Form, the Gatack Double Calibur are shotel-like weapons which resemble stag beetle mandibles. They are attached on each shoulder when not in use. He has a golden Plus Calibur on his right shoulder and a silver Minus Calibur on his left. When the Caliburs are interlocked, they create a scissor-like weapon resembling a stag beetle's mandibles; the "Rider Cutting" finisher is then activated as the charge on the Double Calibur starts immediately.
