My first taste of Koken. Really nice quality. My low light pictures don't do them justice.
10 and 12mm universal sockets with twin ball detents inside which retain fasteners. Figured they'd be great for getting stuff out of or back into places my fingers just comfortably cant go. They're pinned and the joints are very tight. Hoping they stay that way.
Zeal 16mm (5/8") spark plug socket. Has a very firm spring retention so locking extensions would be mandatory for recessed plugs. Really impressive to me was the precision of the detent retention cut-outs in the bottom. Unfortunately my picture doesn't do it justice, however they look precisely machined as opposed to the normal small scalloped sections.
Zeal 1/4" flex ratchet. Only disappointment here is the switch direction is opposite to every other pear head ratchet I have. Sadly I probably wont use it much if ever due to that. I knew their antiquated Proto copies were like that but didn't know the Zeal ratchets (different mechanism I believe) were also like that. Its not fine tooth by any standard but it does have an extremely low drag resistance so the tooth count/swing arc almost becomes a non-issue.
