Seen 'em fly out of peoples hands, and a wrist loop helps you work
longer, just like loops on cross country ski poles. Give the cord
a couple of twists so it is tight on your hand.

I wouldn't want to be hiking with one in my hands, wrist loop or no, and you should be balanced when you are using one, just like an axe
or chainsaw. The movies of people chopping while they walk is
not safe.
