Just competed this for a knife maker. The EDC has Mammoth tooth/ivory scales so decided to use a a pre-aged leather. I also show my design drawing at the end. I import a scale picture of the blade and draw around it. Antique chocolate water buffalo leather. Red stitching to match handle scale spacers. Button stud closure with natural color mount to match ivory handle accent. Left hand carry. Flap closure to fully protect the handle (don't want to chip the tooth)
