While it's probably best to get a custom sheath for your FFFBM (I spent about $60 for a "made while you wait" kydex one), I've also found an inexpensive alternative at Smoky Mountain Knife Works. They make a 12" Nylon Machete Sheath fits MA1465 (designed for use with 12" Ontario® Camper Machetes, although I bought mine for 12" Tramontinas).
It's about 2 inches longer than required, and I'm pretty sure you'd need to use a leg-tie. However, except for the excess length, I feel that the FFFBM fits surprisingly well, not too tight or loose in my opinion, and the sheath is soft enough that I don't believe it can scratch the blade coating. The sheaths only cost $3.99 each, so while I think they're good enough as-is, you also wouldn't be out much if you wanted to try modifying them.
