Sorry, had to finish my workout.
I get the point, I just disagree with it. I personally made an operable AK from scrap parts I ordered, without any restrictions (my kid could have ordered them), because they are considered garbage. It took some tools, some know how, and a lot of swearing but...... when it was done I had built an AK. (I'm getting to the knives, bear with me)
They have been trying to limit access since 1934 with the NFA (which I oppose with all other gun laws) and it simply does not work. They found an operable firearm, built from scrap, in a PRISON. that means - if you made this country as restrictive as a prison, we would still have guns. (I swear, I'm coming back around to knives)
No, I think trying to limit access only achieves two things: (1) it harms those inclined to follow laws. There are actual examples of people KILLED during their "waiting period" (2) it fuels a black market the same as alcohol and drug prohibition have.
This is with tools as complex as guns. Knives? Sheesh, anyone with a piece of metal and some concrete (to rub it on) can "tool up". Try limiting access to that.
No, I totally understand your (or rather Bob's) opinion, I just wholeheartedly disagree with it. Liberty carries risks, that's a fact, but trading even a little of it for the illusion of safety..... count me out.
