The aluminum twisted handle is light weight and fast. Holes are built into the Kontei (bottom) that can produce a very distinguished howling sound. The appearance of this nunchaku is stunning and looks like a streak of light in motion. The Kontoh (top) is a bearing type that turns freely with the Kusari (chain) to prevent the nunchaku chain from binding up. Overall Length: 11 Inches. Chain: 7.25 Inches, Aluminum & Stainless Steel. Handle: Twisted, Aluminum, Shiny Surface. Bolsters: Aluminum, Bearing.
