TOK (Top of Keyway) Tension Wrenches -- How and Why?

[Wizer]

I´ve been thinking of securing my TOK wrench to my finger with a string.
It keeps flying around, and I´ve allready lost one somewhere here in my shop.

This should still be nominated for a sticky. Not because of my newb question, but because of Squelch's analogy!

Try giving it little serrations with a fine file. I find that serrated ends (prybar) tend to stick much better to the top of the keyway.
