Birch bark catches a spark well if shaved into thin strips. Pine resin also works great. If you combine both you have natural tinder as good as it gets.

Pine resin and old man's beard are all great fire tinder materials and I always have good results with either.

I also use my firesteel as much as possible if only just for the practice just in case I ever need it in a real survival situation. This particular steel has had quite a bit of use over the years and is due to be replaced before this year's outdoor adventures are in full stride.
