KYDEX is a thermoplastic sheet that you can bend and mold after it is heated. It is often used to make knife sheaths; it creates a hard protector you can put a knife in when it's not being used. KYDEX is very rigid and is resistant to chemicals, fire, water and impact. A KYDEX press is the device one uses to make a KYDEX knife sheath -- it basically presses the heated KYDEX over the knife and forms the sheath. You can buy a KYDEX press at specialty stores, or you can make one yourself for a fraction of the cost.

Step 1

Lay one piece of the plywood on top of the work bench. This is the bottom of the KYDEX press.

Step 2

Place a piece of the ethylene vinyl acetate (EVA) foam on top of the plywood. EVA foam is flexible enough to help mold the knife sheath.

Step 3

After the KYDEX is heated, wrap it around the knife and place it on top of the EVA foam.

Step 4

Put the second piece of foam over the heated KYDEX.

Step 5

Place the second piece of plywood over the EVA foam.

Step 6

Use the clamps to secure and press all the materials together.

Step 7

Keep the KYDEX press clamped together until the knife sheath has cooled (about 10 minutes).

Step 8

Remove the knife and KYDEX from the plywood, foam and clamps, and proceed to cutting and putting holes in the knife sheath.
