These are great for any bug out bag as they are light weight and effective, they are also natural which is a bonus for those who would like to reduce their carbon footprint.
Lets get started!
a fine edge knife
serrated knife or hacksaw or dremel tool with a cutting wheel (Serrated knife takes forever)
Jute twine (Grab a whole spool, you decide how many layers are in your wrap, I prefer 2)
I try to go with the grain whenever possible, but it's not required.
Simply slide the fine blade along the piece of fatwood at about a 10 degree angle, any burrs will catch on your knife and be cut away easily, leaving a piece of fatwood that wont give you splinters every time you use it. (Warning: ALWAYS cut AWAY from your body, NEVER towards yourself as this can cause injury)
(You can also use sand paper or sanding wheel on a dremel but I prefer to hand shape them with a knife)
