I don't think they would be. And it is to disable somebody idk how good it is against bears.Use them?....are they available to the general public?
Pepper spray also works, but only when used on the animals eyes and nose, it also attracts bears apparently since it smells interesting from a distance so spray and GTHO. Some people think spraying it in a circle around them will protect them from a bear... i just don't know anymore.
Apparently startling a bear is the best thing to do, scare it off. Works on troops of baboons trust me
