Maybe because I'm Asperger, I have always...  

Looks cool
But not much info provided (material, size, etc.).

Just do what I do
And use a dead squirrel.

Or what I do...
chew pencils

I find the insert on the end of a classic Bic Pen...
to be the ultimate stress management device. At a very early age (3rd grade), I learned to chew the little black nubbin out of the end, then suck on it in such a way that it forms a vacuum on my tongue, and then I can flip it repeatedly on the inside of my cheek until it pops off my tongue. Then one chews the nubbin until it is completely deformed and disposes of it. Stress managed. Far superior to talk therapy, or Big Pharma solutions. This helped me get through all levels of school and was covertly deployed once even during an oral defense of a thesis. I swear by it. I recommend it. I would even be willing to give a seminar on how to do it. 🙂
