Shame theres no audio. In that beginning text it says he also was explaining verbally exactly what he was doing, but the film maker didnt have audio recordind device
Handle is birch, also rowan was sometimes used. Box is made of pine, it is so called "päre". It is a thin splice which is splitted from the butt block of fine quality wood, also used for roofing material and baskets etc.
Although the handles are birch it might not be the best idea to use in modern times unless you live in area where theres no true hardwoods like ash or hickory, and you want to locally sourve your wood. Its easy today buying hardwoods, but reason why birch was used its plentiful in north climates, and its kinda ok for handles. I just personally think its quite inferior to really hardwoods like ash in europe. I think thats one reason why finnish, and other notdic axes had that long collar from the eye its for support in that weak spot when you use birch
Finnish traditional pukko knife I think. Lots of practice sharpening and maybe he uses a full scandi grind, which is less strong but takes nice shavings, but might have a micro bevel , I always wonder
