It's weird. Like everyone else, I'm disgusted by the wave of stabbings currently sweeping the UK - but that doesn't stop me being a complete hypocrite by carrying a (highly illegal) 6" electrical knife (plus, of course, the ubiquitous Victorinox).
If things go too far south, viz-a-viz total civil breakdown? I've got a full-on Rambo knife and Samurai sword under my bed. Thinking of investing in a crossbow, too, while they're still legal.
