Help finding sheathes with knot - Largest

Heya everyone.

I’m decently new to sheathes, however me and my spouse are really interested in finding a canine / knotted one.

We both have a taste that leans towards the extreme in size as well. We’ve already looked at Bad Dragon and Primal Hardwere, and this is mostly just a request of help from the much more experienced.

If anyone could suggest as many sheathes as they could, I’d be in your debt. The bigger, the better.
