The Coconut is surrounded by a large cover of bast which we must get rid of before we can open the coconut.
To do so hammer thin slices into the bast hood of the coconut (picture 1). The bast hood is really strong so make your slices thin.
If you finished hammering your slice rip it off (picture 2 and 3).
Repeat the hammering/ripping steps until your coconut is completely bare.
You'll be surprised how small the coconut is compared to the bast cover, at least i was (picture 4).
Note: To rip the bast cover off you can also use a chopping knife or something bigger, but I love my fingers (all ten of them) and this would also add another tool to our material list.
