I make a line of garden ironwork items which use textured rod as vines and the ends are tapered and curled to a tight circle at the tips for visual appeal and for safety. The tiny curl is easy to make with small round nose pliers which I got from Bill Davis. He is active in the Saltfork Craftsmen group. http://www.saltforkcraftsmen.org/ Bill runs ad add in the newsletter - “6" Army Surplus round nose pliers, Make good scroll pliers for small items. $5.00 each plus shipping.” The contact information is:

When I bought five pair I modified four of them to angle the tips to different angles by torch heating and bending. The 15º, 30º, 45º and 90º angles are quite helpful.
