Wood / Bone / Antler Shealth?

[Truelove]

With the exception of (leather covered) Kurki shealths and woven bark puukko types I've seen, does anyone have any pics or ideas for a wooden or other natural material used for knife holding?
Thanks

This is cotton line woven over a wooden sheath then varnished.

these are wood-the bowie has a leather liner.
