The round heads are nice but honestly if you want a decent old school pear head ratchet get a Cornwell. Its not made in Germany but the action is much nicer.
I've got a few of the regular 36 tooth ratchets in the past few years. The 1/4" is plastic and the 3/8" and 1/2" are metal.
Agree if you want to know for sure on current models ask Jens.
