Check out the thread (Posts) on "wrap bracelets" . There are pictures. I made Grandson's some of these in "Earth Tone Colors". They ended up wearing them . I was sure they would become "Decoration for their rear view Mirrors". If you google "Shambala Bracelets", the video is easy to follow.
there are some men on this site. check back,

Do you know Helm weave? I have made that using rubber rings for the inner rings and no clasp (just stretch onto wrist), and have sold them to many males. But that is a bracelet, and now looking again, I see you are asking for a necklace. Here is a link to a chain maille specific forum, you may get a a better response there. I don't know how many people here do chain mail.
Sorry, you'll have to copy and paste because the linky thing isn't working for me.

Have you thought of using African beads. They make some good looking "tough" beads. My LBS has some very good ones.
