Well, since most antler sheaths oversized, decoratively branched, and I have no use for art knives since I use them, and likely the birch lined leather wrapped sheath lighter, and just as safe against splitting through, and perhaps safer since antler only pinned at bottom, plus, I plain like leather, it'll do for now.

The fancy stuff I only admire in photos or museums, then I go home and use my stuff to compensate. Seems to work, most times.
