Here's an easy step by step tutorial on how to make a leather sheath for your Scandinavian knife. Place the knife on top of the leather you will be using to make the sheath. Measure the tip of your knife away from the bottom of the leather for about a size of the width of your index finger. Wrap the knife with the material you're using to measure the length and width of the sheath. Mark the edges of the leather that will be needed to make the sheath. Cut out the leather by following the markers that you've made from the previous step. When the part is already cut out, you're now ready to make some finishing touches to the shape of your sheath. This is how easy it is to make that nice looking sheath for your Scandinavian knife.
