Knarre Zyklop Metal with a square drive. Slim design for working in very tight spaces. The double ratchet construction allows for a fine tooth division of 76 teeth from 38 robust teeth, with a return angle of just 4.7°. Very smooth directional change thanks to the non-loss square drive, now also featuring a secure socket locking function. Forged all-metal ratchet (chrome-molybdenum) for exceptional durability and long lifespan.
