I believe there is only one manufacturer of Finnigan pins. That company also manufactures combination pullers, I believe. It is used by banks to change the combinations on safes when employees leave. Only a few main branches generally have these and new employees are often sent to another branch to get the combination puller.
Yep, and it's in China. Back in the day we Americans chiseled our Finnigan pins out of solid granite, but this new stuff falls apart first body you run over.
