thumb A<unk> , also called a<unk>  pinwheel or<unk>  neurowheel, is a medical device for neurological use. The<unk>  was designed to test nerve reactions (sensitivity) as it rolled systematically across the skin. A<unk>  is generally made of stainless steel with a handle of approximately in length. The<unk> , which has evenly spaced radiating sharp pins, rotates as it is rolled across the flesh. A disposable plastic version is available. Because of hygienic concerns, these devices are rarely used for medical purposes any more. Robert<unk> , namesake of the<unk> , is sometimes incorrectly credited as its inventor. According to<unk>  himself, the device was in widespread use in Europe when he lived in Germany. While he did not invent it, he found it "an indispensable part of the outfit for everyday neurologic practice," and recommended its use to his colleagues in the US. The<unk>  is also used as a BDSM or sensation sex toy, and is often used as a device to tickle a victim (also called a ‘lee, short for “ticklee”) in the fetish of “tickle torture,” one of the most popular and fastest growing fetishes in the world today citation needed. It is sometimes used in other settings while connected to a violet wand electrical device. Clothing pattern-making can use a version of the<unk> , called a pounce<unk> , to transfer markings from paper to fabric. Pounce<unk> s resemble standard<unk> s in shape but have wooden or plastic handles.
