Previously i've made a kuksa or wooden cup from a straight piece of beech (http://www.instructables.com/id/Kuksa-wooden-cup/
Recently i was lucky enough to find a fallen birch tree whilst out canoeing, figuring that nobody would mind i whipped out my rescue saw and harvested a few of the more cup sized burls.
Burls are growths on the sides of trees that form in reaction to damage, injury or infection. they grow into weird patterns so look amazing once polished up.
Here is how i made a more traditional kuksa from a small birch burl. I've some bigger ones but im leaving them to dry properly and till ive more time to work on them.
Due to the shape and size it ended up as a more decorative object rather than a functional cup, though it could always be used as a shot glass!
As ive tried to before, this was made using only tools i do or could easily add to my wild camping kit without too much hassle.
Tools and materials:
Saw- For harvesting burls (I keep a large toothed plasterboard saw in my boat for emergencies)
Small knife or chisel- For cleaning up the outside of the burl
Small saw or large knife- To remove large nobbles
Hook knife- For forming bowl
Drill/ Awl/ Knife- Something to make a hole
Oil and cloth- To polish
Leather and antler scraps
