I would think that whatever the final result is that is should be duplicateable and durable so thats its attainable for others to do as well. I tend to agree with Justin on the sinew issue. I don't feel confident enough in my skills to make one as short as these yet, however if I did, I would sure want to make sure I could use it regularly as needed. That to me is what the sinew would ensure. Durability. As far as reinventing the wheel, well there is wisdom in that ole adage.Just my two cents worth.
