The KI Sims Anal Speculum is a stainless steel instrument for medical-themed play. Two hinged blades open when you squeeze the spring handles, and a set screw locks them in place so you don't have to keep squeezing. It's a piece for experienced players who enjoy exam roleplay and controlled anal stretching, not a beginner's toy.
The two blades are fenestrated, meaning they have open windows along their length. Squeeze the plier-style handles and the blades part; tighten the set screw and they hold that position. The handles have horizontal ridges so they don't slip in lubed hands. KI describes the steel as surgical grade, and it can be sterilised and reused.
Steel has no give, so preparation matters more than with silicone. Warm up with fingers or a small plug first. Warm the blades in warm water, coat them generously with lube, and insert them closed. Open only a little at a time, check in with your partner constantly and lock the screw at a comfortable width rather than the widest. Release the screw and close the blades fully before removing it. Stop if there's sharp pain.
It suits people already comfortable with anal play who want the look and ritual of medical play. It's not a starting point for anal stretching; a graduated set of plugs from our anal toys collection is gentler. For a three-bladed design, see the XR 3-Prong Anal Speculum, or for a vaginal and anal option, the KI Miller Speculum.
Wash it in warm, soapy water after every use, paying attention to the hinge and screw. Because it's stainless steel, it can be sterilised between sessions. Dry it fully before storage so the moving parts stay clean.

Helpful answers about KI Sims Stainless Steel Anal Speculum with Locking Screw.
The KI Sims Anal Speculum is used in medical-themed roleplay and anal play, opening the entrance gently with two steel blades. A set screw locks them at the width you choose. It's for experienced players; beginners should start with plugs before trying a rigid instrument like this one.
The locking screw on the KI Sims speculum holds the blades open once you've squeezed the spring handles to the width you want. That means nobody has to keep gripping the handles. Always loosen the screw and close the blades fully before you remove it.
Use a thick lube with the KI Sims Anal Speculum, applied generously to both blades. Because it's stainless steel, both water-based and silicone lubes are fine. A thick anal lube stays in place better while the blades are opened slowly.
Yes, KI says the Sims speculum can be sterilised and reused, since it's made of stainless steel. Wash it in warm, soapy water first, paying attention to the hinge and screw, then sterilise and dry it fully. Keep it in a clean bag or case between uses.
Yes, the KI Sims speculum feels cold at first because stainless steel holds room temperature. Run the blades under warm water for a minute before use, then dry and lube them. Some players like the chill as part of a medical scene, so ask your partner first.
