A bicycle chain break tool. After a metal one broke, this helped solve the problem.

For use with an m6 pin. (Suits the bike tool pictured). The hole is on the tight side, go slowly when 1st tapping the thread and open up with a drill slightly if needed.

You could turn down the end of a bolt to suit and use a hex head.

1st version, perhaps I'll update with some refinements.

Hope it helps with a walk !

fancy being a bit of a patreon..?
