this bow definitely belongs here,
in my younger days I made a couple of this style,, first one was a total failure, the whale rib bones I used were much too old and dry, after it broke, which was soon, lol,, I forgot to remove all the valuable sinew cable that took me months to make,, my dog found where I had been storing it,, well he got it, all that work gone..
the second bow I used raindeer antler it worked out great,, in the video that's what it looks like he is using to me,, more than if it was bone, notice the pinkish look to the pithy area, it really reminds me of the way the antler looked when I used it,, BUT I could be WRONG,, I have been wrong before..
I cans say the mouth drill is awesome, as is his complete tool kit..
great video post! thanks
