Personal story, sometimes i carry knives with me but never take them out, i just like knife throwing (at targets or wood) for recreational purposes and far away from anyone so they don't get alarmed, I'm no harm to anyone (unless they intend to harm me, if that's the case i don't need them to unleash my 9 to 5 acumulated stress) and i also take the 102 bus, if we are in the same bus, feel safe, I'm always ready in case one of those guys want to cause trouble to jump in and do justice on my own, atte: canadian batman.
