I'd agree about not threatening an intruder with a weapon, I'd rather if it came to blows he never saw it (large heavy and blunt object) coming... A weapon is last resort and numerous cases have shown a weapon 'brandished' not used by a householder was then used on it's owner by the intruder. Why arm the sods???

As a personal thing I guess I'd go for a classic katana if I wanted to go into the Ai cutting fraternity. INFI is awesome but the AK styling is just too contempory, now a formal katana in INFI would be a thing...

Andy, I suppose it would function as a two-hand-grip parang but it didn't strike me as curved enough to really sabre cut well.
