>>898702There are none that I know of. You might be able to find a random sheath that fits. Amazon seems to carry some molle machete sheaths. I can give you the measurements on it if it helps...
19 3/4" long
14 1/2" blade
2 7/8" at widest point near the front
I recommend owning a lighter-weight machete like this if you're also looking at xbox hueg machetes like aranyik, some condor (half the condors I've used have chipped readily during reasonable use btw) or a traditional kukri. No hate for big fat machetes, I'd just get a lighter one for variety and these are dirt cheap and work.
If you don't like the shape (I LOVE this shape) tramontina makes other shapes... I'd get one of the wood handle ones though.
