I just saw an expensive 15cm mezuzah with tiyug that was obviously done by a metayeg. It had a metayeg's typical "signature"
- little straight lines without ziyunim whenever in the vicinity of a letter above rather than take a few extra moments to make properly, particularly in a mehudar ksav, (laziness and amaratzus)
- tagei Yud, which few Ashkenazi sofrim do
- While he he was fairly successful in putting most of the Bedek Chaya tagin close to the left edge, there were a few in the middle as done in a Sephardi ksav
