So far my debarking experience is limited to oak but I'm getting a lot of practice lately. I've been using my old Boy Scout hatchet and a hunting knife.
I've found that once I start the blade between the wood and bark, if I pry the blade sideways (across the grain) a lot more bark comes off as I move the blade down the log (with the grain).
As you tend your fires, you'll get plenty of practice working on the next batch of wood. You kinda start figuring out what methods work.
Rick has a lot of experience with using real wood. He may have some good tips too.
If it aint broke, Break it!
Then rebuild it better.
