The title says it all. It is a knife sheath made out of a inner tube. It can even slide onto your belt.
Step 1: Materials
You will need:
1-Bicycle Inner tube (split lengthwise)
1-Spool of Thread (I used canvas thread)
1-Knife or Something of the Sort
1-Thing of Adheasive Velcro
1-Pair of Scissors
Step 2: Sizing It Up
Step 3: Sew, Sew, and Sew Again
Get your thread and needle and sew up both side. Be sure you don't sew up the top flap, and make sure that it is inside out.
Step 4: Flip It Around
Turn that bad boy inside out. I found the best way is to push something like scissors or a pencil from the bottom.
Step 5: Velcro, Velcro, Everywhere
Not really; just add a little on the flap and the other spot, shown in picture.
Step 6: The Belt Loop
Cut two slits about a half inch to an inch away from each other. Both slits need to be long enough to slip your belt through.
Once you do this, you are done! Now go embrace your inner Bear Grylls and run through the woods like a maniac with your new knife sheath by your side!
