I have made lots of camera straps to my liking by going to a leather supply shop and picking up straps and useful scraps for things like neck pads. Tools that are useful include a hole punch, a rivit setter, and a good sharp blade for trimming the leather to shape. It sounds as though you might have a Hassy strap you don't like. You could just reuse the camera attachments in a homebuilt strap. Often I install sturdy plastic snap devices (available at most hardware stores) near the ends of the strap so that I can quickly remove it when the camera is on a tripod. Of course, the formidable prices of even used Hassy straps may make you think twice about dissecting one to make (or to have made) a strap more to your liking, but it is a heavy camera to use feeling discomfort around your neck or shoulder.
