How to make birch bark handle for a Laplander blade

I visited Roselli's factory some time ago and I bought two of their biggest blades, Sami -Laplander knife blades. These kind of blades are called "Leuku" in Finnish. I desided to do birch bark handles for them. I wish this opens your eyes how to do it. As you may notice, it's rather labouries to do it. I think there's going to be a video soon introducing these knifes when ever they will be ready. Music in this video comes from Ulla Pirttijärvi, Finnish Sami singer. Look at video Project Lapin leuku and you will see these laplander knifes finished https://www.youtube.com/watch?v=g9Imx...
