Ko-ken 3726ZB - 3/8" Sq Drive Ratchet Handle 72 teeth, Flexible Head, 178mm Length Z-series

Giving this 4 stars because it's beautifully made as youwould expect from Koken. However, the force needed to release the socket detentw with the push button is enough to fold the flex head over as it's a non-locking flexhead design. This makes removing socket slightly more tedious than I would like
