12-Strand Climbing Rope

12-strand solid-braids make for firm and round tree climbing rope. They have a "nubby" feel that is easy to grip, and work well with traditional climbing methods. They are a poor choice for use with mechanical devices, due to their size and hand. 12-Strand is an older construction for tree climbing rope, but it is very durable and easy to handle. (16-strand, 24-strand, and Kernmantle rope have replaced 12-strand for professional climbers.)
