But what are these other uses? I can't think of anything OTHER than on a horse. Any other application, simpler knots suffice.
KISS.

I am reluctant to add the fiador to my bag of tricks until I can think of such a use. For instance, I commonly use the zeppelin Bend over the sheetbend even though it is more difficult to tie because

1. It is stronger then the sheetbend
2. It doesn't bind even after stress is applied.

What does the fiador bring to the table that the bowline on a bight with an additional sheetbend doesn't? Except for equine applications, the fiador is listed as a decorative knot only.
