From looking over some obscure Japanese tool suppliers a while back,
it looked like there are still traditional Japanese blacksmith tool makers, that “hand forge” cat paw nail pullers.
The prices were several times or more what a similar nail puller would cost from one of the higher production Japanese tool brands, who make similar nail pullers.
I have no clue whether that nail puller would have been made by an individual blacksmith or small scale tool manufacturer, or a larger manufacturer.
Another issue is that Japanese tools that get sold in the USA are sometimes rebranded by a single Japanese tool brand or importer, that didn’t actual manufacture the particular item.
(On the plus side for this, these import brands generally don’t import really low quality items that exist for the Japanese home market)
