Name Ideas for Handmade Jewellery for Boys?

So my little one has started making hand made jewellery for himself and his friends and we've had other people interested in buying these so I'd like to give his little venture a name.

Any ideas for something creative that's quite boyish? Seeing as there are so many girly things out there, I would really like to focus on the fact that this is something aimed at the boys. It's all mainly beaded jewellery, but I don't like the sound of using beads in the name.

Any inventive ideas would be very welcome.
Thank you!
