Please allow me to let it be known, when considering a weapon, even for display or martial art training, that said person who is thinking of buying-owning, thoroughly check their local/governing laws.
Recently, a student of mine, changed residency, and such laws of his new residence, banned certain weapons.
He did not thoroughly check his local/governing laws, and is now in a heap of legal ramifications.
He tried claiming "ignorance of the law", but this is not going to work.
Now, I have to travel to his new city of residency, to report to the legal sector as a character witness type to get him out of legal trouble-if possible.
Weapons and ownership can be serious, leave the fantasies alone when legal issues have to be first addressed
