A leather sheath is a classic option for your favorite fixed-blade hunting knife, but it’s also not waterproof or as durable compared to some modern day options. Try making a Kydex sheath instead.

Squeeze the Kydex in a vise. Clint Ford

Heat a sheet of Kydex to 350 ˚ F. Be careful—overheating will ruin the material. Wrap the heated piece around the spine of the knife, and using neoprene foam for padding, squeeze the Kydex in a vise or with clamps with as much pressure as possible. Let cool and set for 12 to 15 minutes.

Trace the desired shape of your sheath with a colored pencil. Be sure to leave at least an inch margin around the knife for riveting. Cut out the shape with a band saw, scroll saw, or a pair of sheet-metal snips. Sand the edges smooth and straight.

Press rivets slowly. Clint Ford

Drill out ¼-inch holes evenly spaced along the edge of the blade. Press rivets slowly and smoothly to prevent ­splitting. Bolt on desired ­hardware, being sure to apply thread locker. You can also run ­paracord through the rivet holes for lashing the sheath to something.
