Zero Enigma, I am a chem/pyro expert and you are so right about nitro, Too unstable to start with and it gets more unstable with time and heat. You are better off carrying magnesium powder, powdered iron oxide, and a firebrick cone. Separately they can and are used as art supplies. Well maybe not the ceramic. Together you get thermite and a stream of white hot iron that will cut through about anything. Little fireworks might scare off a thief but will also P O the police. Research the threads on liquified gases.
