I was looking through the Hufnagel site the other day and found these, absolutely beautiful.

(Handlebars)

Anyway, I was wondering, how they would go about designing these.....

Would they use software and if so which software.... CAD???

I would like to have a go at designing some myself..

Also, if and when I did design some, what would be the next step in getting them built... Either by myself or someone else..???

Thanks..
