Archie, I hope you weren't being sarcastic/facetious in your last post. If so, then ignore the following reply.
Now that you've come out and flatly stated the situation and your concern, I understand where you are coming from.
1. Most people are pretty effing stupid. You know how stupid the average person is? Well half of them are STUPIDER (or More Stupid, whichever you prefer). AND they are breeding and passing legislation! No other society caters to the ignorant, the stupid, the irresponsible, and the criminal like ours does. Hey, I'm no genius either, but puh-lease!
2. People have a tendency to fear what they don't understand. I'd say most people have no real familiarity with knives (we're not a bladed culture). As long as your Sebenza hasn't been used by a Bad Guy in a movie, I'd say you're still ok. Cause you know that the stupid people believe 100% what they see in the movies and on TV. Maybe they're just jealous that you even HAVE a Sebenza. It's not like you were performing ordinary cutting tasks after flipping around a Balisong for 5 minutes or were using a Rambo or Crocodile Dundee sized bowie...
3. Current laws are often very poorly written. Many are unclear; some just don't make any sense. E.G. If you borrow something from someone with the intention of returning it but later change your mind and keep it, it's not "theft" (even though the bottom line is that you've deprived someone else of their property )(CA PC). Another, why are M-16's and Franchi SPAS on the banned list and Mini-14's and Benelli's not? They are basically the same. Why would you ban certain types of AK-47's and not other types of AK-47's (differences being as little as having or not having bayonet attaching hardware)?
Like NGK is saying, if you (we) use our tools in a discreet manner, you (we) will most likely never have a problem. When people's actions start causing fear or apprehension in others, and it happens often enough, then stand by to stand by.
