Agreed, Bear spray would be ideal.
In other news, a good knife for what you are looking for could be the BK7, or BK9. They're pretty affordable, and are super useful for woods work. The BK9 is the chopper that you're wanting, but the 7 is a sweet all around knife. Its large enough to chop and baton, but also lighter than its siblings (the BK2 and the BK9), so it won't weight you down as much when out and about.
