Kukris are typically MORE effective than a katana in untrained hands since the weight distribution allows for more powerful swings, even with novices. This is why they have fire axes (weighting principle similar to that of the kukri) and not fire katanas, heheh.
I would either go completely Travis Bickle, mohawk and all:
Or dress up like the Fonejacker, which is similar in dress, but I would have a silly balaclava on and speak in countless silly accents:
And of course I would have a gun because not having a gun is fucking suicide. Any of you who thinks they can take on dangerous criminals with edged weapons is off their rocker. Guns are the equalizer, and edged weapons are the "less than" sign (<).
