I have recently tried my hand at making a few sheaths for my CCF hawks.
The square front tanish one was my first and the black my second, after some time to see what I liked. All it took was some leather, snap kits, copper rivets and contact cement. It has been a fun learning experience.
I hope to make a nicer one for my damascus bear claw hawk next. I used rawhide strips for hanging them on me.
It is fairly easy to do. Have fun.
