What is this wiring style called?

[the greek]

I used to use the spooled safety wire. You can get it in .042, .051 and .062. Comes in a can and is very soft and real easy to form, almost too easy. I just use regular old 308L welding rod anymore. Its plenty easy to form and actually holds shape better. As for functionality it think it does help somethings like spooks especially. With no hole or grommet I think you get a better [longer] glide if thats what your looking for. For swimmers i don't think it matters except for real small stuff. You are able to keep a bit more wood in the plug and not have the extra hardware. I also fill my smaller stuff with micro balloons mixed into the epoxy to help with the extra weight epoxy brings to the plug. Don't know if any of the extra steps has any real scientific advantages but it does seem to help on some of the things I've built.

I've been using cut-offs from 304L thru wiring stock and have not had problems making the hangers out of that.
