very cool knife,looks to be the perfect size too
as far as roo hide in the US.
we have a fabric outlet store i the minneapolis area.they have every type of fabric you can think of
not to mention they have just about every type of leather too.they have regular cow leather,ostrich leather,tanned gator skins.
they have hair on hides,hairless hides etc.just about everything and what they dont have Tandy Leather has the rest.
i would just call around and ask the fabric/leather stores ya never know,god luck
