I made 2 versions for this one.
Usually on a curvy bolo-y blade like this I default to my exposed spine style.
But I have been making a few sheaths for a few customers that really get aggressive in the woods and want a more straight drop style sheath.
so what I do is make a "knife" blank and mold to it.
here are both styles
my Original Exposed Spine
and a fully enclosed version.
