Knife Handle materials
The most common knife handle materials for beginners is Wood, Horn, Bone, Birch bark and Vulcanized card.
Both Brisa and Puukot supply materials for knife making. I gather my own and call it “chop local” (pun intended).
Chop Local
One easy way is to get your own wood supplies from a Forest or a Garden. Ask Landowners consent. Speak to local Lumberjacks. If you see a neighbour chopping down a tree. Ask for some.
Gluing and sealing the ends will help avoid splitting during the drying process. Remember the wood (without assistance) will dry roughly 1 inch per year. EG: a 3 inch thick plank will take 3 years to dry.
