Ko-ken 2725Z Z-EAL 1/4" (6.35mm) Drive Ratchet Handle 1/4" (6.35mm) drive, ultra-compact head (17.1mm thick, 20.5mm wide). When combined with a slim Z-EAL socket, its extremely thin profile allows for use in narrow spaces. New structure 36-tooth gear ratchet handle. Ko-ken has developed a ratchet mechanism with a structure that focuses on the "light free-spinning torque" that is a characteristic of their ratchet handles. It achieves overwhelmingly light free-spinning torque compared to the ratchet mechanisms with a structure that uses an integrated pawl to push up the gear, which are currently widespread in the market. Free-spinning torque is at the same level as conventional two-pawl systems. Ko-ken's ideal ratchet handle.
