It works YAY

nice looking sheath I'm not sure I under stand the wooden block does it act as a keeper?

The wood protects the blade as it is soft pine, protects the leather from the blade and does act as a keeper as it is a friction fit plus ther is a drain hole in the bottom to prevent gunk from accumulating. I read about using wood on a traditional nordic sheath site there are others out there made from plastic and such.
