Hemp
Rope fiber from the stem of Cannabis sativa; as bondage rope it is denser and heavier than jute, grips about as well and softens with use.
Hemp is the common English name for Cannabis sativa grown for fiber, seed and other products; industrial varieties are bred to contain very little THC. Its textile and rope fiber is a bast fiber from the stem. As bondage rope, Shibari Study describes hemp as denser and noticeably heavier than jute, comparable in how well it holds frictions, and non-compacting: it keeps its shape under strain, which makes knots easier to untie. It needs little or no batching oil but has a smell some people dislike, and it can become softer than jute with use. Karada House adds that it is more durable and gentler on sensitive skin. In Japanese, asa in its narrow sense means hemp (大麻), and Shibari Study notes that early translations often equated asanawa with hemp rope.
