Batoning wood is a great skill to learn.
If the campground doesn’t allow you to gather wood from the forest you’ll need to cut kindling from the firewood you purchased, which is easy to do. It’s also a handy skill to have because it expands the functionality of your knife.
Throw a pair of gloves on and position the blade on a corner of the firewood. Then, with another piece of wood, you’ll tap your knife downward, shaving off a small piece of kindling. If you do this 4 or 5 times you’ll have plenty to get a nice fire started.
Note: The safest way to do this is with a full tang knife (a blade that extends all the way through the handle). Don’t try this with a kitchen knife or pocket knife that has no business hacking into a log.
