I’ve seen them at Rio’s booth for years. They’re pretty, and lord
knows the hammers are sexy, but they are teeny.
The short answer is that of course you could make your own tool,
either plier or stake, to do the same jobs.
The real question is do you ever do work that would benefit from
micro- stakes of those sizes & shapes?
If you do, then you must ask yourself if it’s cheaper in ultimate
terms to trade money against the time to make your own. If yes, buy.
If no, make them yourself.
The things that can be said about the stakes is that they’re already
done, beautifully polished, and very hard (and stainless). (I know
the hammers are RC50 (tested one myself even). I suspect the stakes
are equally hard, but I’ve never tested one.)
There appear to be a fair number of goldsmith scale workers who
really like them. Me? I think they’re pretty, but as more of a
silversmith, my main urge is to pet them, rather than hit them with
hammers. Too small for me.
