A Wartenberg wheel, also called a Wartenberg pinwheel or Wartenberg neurowheel, is a medical device for neurological use. It was originally designed by Dr. Robert Wartenberg to test nerve reactions (sensibility) as it rolled systematically across the skin. A Wartenberg wheel is generally made of stainless steel with a handle of approximately seven inches in length. The wheel, which has evenly spaced radiating sharp pins, rotates around as it is rolled across the flesh. Because of hygienic concerns, these devices are hardly used any more. Now you know what it is, now lets show what else it can do. The Wartenberg wheel is also a sex toy, and this where the fun starts.

Wartenberg wheel is a fun little tool; you can run it across the nipples - always a fun one. You can roll it over an arm, this gets mixed responses. You can bounce it on back, points down of course - always a shocker. Roll it across a mans cock; if you wanted his attention, you got it. Sadly, due to the tenderness of a woman's' vagina(or pussy if you prefer), it is not recommended there. But if you really want to make her squirm you could try it softly. If you are looking to push your boundaries this just might be a good place to start.

Now some little facts about it:

Similar in appearance to a pizza cutter, this wheel of prickly little pins is rolled over a person's skin, generating a unique, tingly sensation which many people really respond to. Wartenberg wheels are a popular BDSM toy, proven by its constant presence on the bestsellers list of BDSM retailers. The pins are pointy enough to feel quite stimulating wherever they go but are not sharp enough to puncture the skin unless excessive pressure is used.

All in all, a very useful sex toy

I still like playing with the wheel. It still gives a different sensation as it rolls across the body. When you can't move it away from an area, there are spots that tickle and there are spots that it hits that make goosebumps on the arms and legs. I like the way it feels when it is done for pleasure. I still like it in our toybox.
