They look like they work pretty good. I wonder what they cost? I don't see any real quick, easy way to make them.

I didn't see any patent pending on them but that guy shows you what will happen if you copy them at the end of that video.

He dont need no stinkin patten # he got a 12' bull whip.

I don't hit many rocks.

I can see how it might be harder to lose one but I'll bet I still can.
