Hi Tom, this is for fixing the handle to the body of the bag - it has to have the screws, stitching isn't strong enough on such a small section (it is leather, and the stitch apparently makes a cut rather than a hole like in textiles, so it ends up weak from the perforation).

Can I ask what you mean by 'lost wax and polish'? I'm not up on the terminology of metalworking I'm afraid. Do you mean the cnc part could just be polished and not require plating for a nice finish?
