No specific reason. I think it is an important tool for urban prepeardness. Just like a silcock key, boltcutter, pliers etc etc.

Never know if you have to pry open a door to get in or out in an emergency situation. Or bust a window to escape.

This one is not too big (10inch) or heavy (about 0.7 pounds) to be carried in a backpack. And still the iron is thick enough as not to bend when used.
