This!Harbor freight in southern plaza sells the magnesium fire blocks with fero rods in them for $2 a piece .
Menard's has it in a large bag!I usually just use a couple of slivers of "fat wood" - the stuff is awesome, it's basically a resin/sap/tar heavy pine wood that ignites easily & burns slowly while also producing a very nice flame.
Drier lent is pretty handy. You can use it like you would cotton balls with a little Vaseline in a zip lock bag.
We have an inside wood stove. I stuff a toilet paper roll full of it to start a fire.
You could look all day for a birch tree here in Southern Indiana. They are few and far between around my place.
Do you guys have them up in the "flat lands"?
In my woods bag I carry a candle and lighter. You can skip a lot of time consuming preparation when using a candle.
I too keep dried birch bark around,and the king of fire starters has to be FRiTOS corn chips.
