I used plumber's solder to join the wire together, so it's safe. I wasn't too happy with the join because I was using my dollar store soldering iron, and it seemed to have trouble getting the workpiece hot enough. The join is still pretty strong. Next batch, I'm thinking of using my blow torch.
The spiral one ended up getting turned into a holder for my instant read thermometer so I can keep my hand cool while checking temps.
These are prototypes, so they are a bit ugly. I picked out the poplar dowel handles from the scrap bin.
