Does it work the same way for square wire, or does that little bit
of skew that the coil introduces create a problem?
I would strongly suggest sawing all of them at the same time: if you
saw straight, the skew will be the same for all the cut edges, so
they will line up perfectly even though they are slanted…:-)…!
This is of course true for round wire as well.
I’ve never seen square jump rings here in Israel, but I usually make
everything myself. Sorry.
