Thus PGmc *xaubidaz c.500 BCE PGmc k which seems to be the natural fit for unaspirated stops.
We can find other "handy" words in this line: PGmc *gripa- ‘part of hand which holds something’, easily comprehensible from ‘to grip’, and PGmc *hneba- ‘fist’, seemingly from PIE *knep-.
It is also feasible to make another interpretation from PIE *ḱent-: PGmc *hinþan- ‘to pin down, hunt, reach, etc.’ bridges the way to hand-relevant functions good enpugh for me.
It leaves us with a suspiciously parallel development between Gothic fra-hinthan and Latin pre-hendere that taunts us to believe PGmc *handuz and the related verb was somehow in some way influenced in the 1st millennium BCE by an Italic language.
