Most of the new harnesses have a razor gizmo in the shoulder strap to cut yourself free from the harness.
A few that I have also have a shock absorber built in, just like the ones used in industry and construction. It amounts to a good number of folds sewn together, the sewing ripping in a controlled manner playing out slack when you fall.
The belts of yesterday were like the belt used to hold up your pants. an article I read in a bow mag years ago told about the amount of force your internal organs took in a fall because the force was not spread across the whole body. The other problem was you could fall thru the belt ( too loose or to skinny ) The belt could come up around your chest and suffocate you in a minute or so . Or if you had a bit of a tank up front it will cause you to do a nose dive as you would be over centered throwing you off balance.
just remembered reading an article in a hunting magazine or newspaper about a father and son hunting. The son did not show up at the assigned meeting time and the father went to look for him at his stand. The son had fell; hissafety belt got around the sons chest suffocating him. The article said that the son was kicking so violently to get free that he had kicked his shoes off of his feet.
We tend to take a few more chances with our safety while hunting, and that is where we end up getting hurt. We over look things that could cause us major trouble. A friend had a couple stands up in a fence row. Right under the stand was part of an old steel fence post. Ifhe ever feel climbing into the stand he could have impaled himself on it.

His other stand had small trees and bushes under it that he cut leaving about 12 inches of the stumps that would have done the same thing.
It is very important to use our safety equipment and more importantly to use it correctly.
