An anal hook — ass hook in North American informal speech — is a sex toy built for anal penetration and the bondage scenes that hang off that penetration. It looks like a fish hook on purpose: a curved bar, a ball on the inserted end, a ring on the other. Stainless steel is the usual material. Other metals and finishes exist, but the common shop object is a rigid steel curve, not a soft toy. Steel does not give when the wearer moves; used badly, a rigid hook transmits force straight into tissue that a silicone toy would have yielded around.
The standard design is simple. A metal ball seats inside the body and keeps the curve from slipping out. A ring at the free end takes rope, a clip, or a decorative tie. Unlike dildos and anal beads, which are often made to bend, anal hooks are almost always inflexible. That rigidity means the toy is for tension, not for holding weight.
A bondage hook is never a load-bearing restraint. Do not hang a body from it. Do not use it as the anchor that takes a person’s weight, a hoist, or a hard yank. The injury potential is the whole reason for the rule. What people actually do with the ring is lighter: the hook is sometimes woven into a rope harness on the torso, or into rope tied into the hair, so that a turn of the head or a shift of the chest tugs the curve. In those setups the harness or the hair — not the rectum — takes the load. Treat the steel as inflexible, treat the ring as decoration-plus-tension, and never ask the toy to hold a body.
