Hi I've been fly tying for over a couple years now and just recently my vise's jaw broke and I can't seem to find a replacement for it. The vise is a Spearhead Vise I can't find it anywhere it's like a one of a kind vise. I was wondering if anyone knew a website or had any advice for me to find a new jaw for it. The pictures I attached are what the bottom of the jaws need to look like for my vise.
