David Hölter demonstrates how to design and create a leather sheath using frame construction for a fixed-blade knife. He explains the fundamental principles and presents various versions in different styles. Two knife sheaths are described in detail: a frame-stitched sheath with an attached belt loop and a frame-stitched sheath with a belt clip and securing tab. Each step is explained with both text and images. Patterns for both sheaths, as well as a foundational section on materials and tools, complete the volume.
