Its for a gift to a friend in the states who is an avid hunter . I do know about the laws in the UK . At my age knives I use are in the kitchen. I took up leather working when I landed in my wheelchair as something to do I have made a few things but wanted to make a shoulder harness for a hunting knife set that I am getting for dear friend itd for a 7" hunter and a Skinner . I would appreciate any help I can get I have seen a few online but want one that fastens like the shoulder rig for a gun .
