This is probably a bit of an old one but in my 10cm Billy as well as a tuna can stove I stuff it with 00000 fine wire wool. This make a great tinder and even work when wet ( just squeeze it out first) with a firesteel. It get very hot and is even better if you have some lard or fat. just strike, blow and the fat will flame.
You can also use it to finish off spoons etc ... and ...urr...clean your Billy
As I said I know it is a bit of an old one but I thought it was worth the post.
