The hook is an essential bit of meat cutting gear BUT they are, or should be as sharp as your knife so they don't float around a back pack very nice and they do go into your tender parts as easy as they go into the meat your working with!!!
There is a plastic knife case that holds two boning knives and it has a place that your hook will snap into with the hook point in a safe direction, Dexter-Russell, Inc.
I just noticed that the link in the OP was to a 5in or 6in hook, those are huge hooks and hard to use on lighter game animals, on buffalo or beef they are good but for game you want a 4in hook!! Butcher Packer is a great site to get supplies from by the way and they have the 4in.
