A few new gadgets #2

There seems to be many nipple clamps on the market but not many clit clamps? I am interested in finding out more about securing and gripping the clitoris. My online sub uses one very succesfully and loves the sensation,but I know it is sometimes hard to secure them in place. Any info gratefully received!

I've used a tweezer style clamp with good results--depending on how tightly it is closed it can range from actually pleasurable to way to intensely painful and various intensities in between.
