A friend of mine has made himself a small hook. He can thread one end between his bow and its string. The other end is a hook. This thing let him hook up his bow just nearly anywhere (basically it's for branches on trees).
As he made it from a white-tail antler, I tried to create on for myself. However, the antler I had didn't had this sharp angle needed to have a proper hook.
Is there something similar - kind of an outdoor universal hook - to buy?
Edit: This hook has to comfortably fit in your trouser pockets, so that it can be taken out easily.
