All Materials On the Fly Friction Fire: Knife Only

Описание: This is a complete on the fly bow drill friction fire using only a large tracker knife. I gathered everything on the spot from the wild.
For the spindle & hearth board I used a tree branch from a dead cottonwood that was on the ground since it hasn’t rained in a couple of weeks.
I then cut a small slippery elm tree from an area that needs cleared out, so it needed to be removed anyways. I stripped its bark to make a bowstring from it.
I had several strips of bark ready to braid if I needed a stronger cordage, in case my initial plan didn’t work. Fortunately my first choice worked just long enough for me to spin an ember.
I just used one strip of elm bark. I twisted it up in one direction & tied a knot in both ends, before attaching it to the bow. It did eventually break on me but not before I managed to create an ember.
The bow was just a stick that I picked up off of the ground & put a split in each end to hold the tree bark cordage.
I used a piece of green elm wood from the same tree for my bearing block.
For the tinder bundle I just used some dead inner tree bark with a little bit of wood curl shavings & cottonwood seed fluff.
The ember catch was just a piece of dead inner tree bark.
