In referring to it as a 'tactical tomahawk' I would suggest you're making it very difficult to justify:
Tactical - "Of or relating to combat tactics"
My suggestion would be it is just another axe, being employed as a chopping axe for light kindling. If you then happen to throw it within the confines of your own property that's your prerogative.
If you were stopped by police carrying it within a vehicle or was it stored in an accessible place within your property should they visit however, I would suspect it may be a different conversation.
