Knowledge that kills

Ignorance kills. So does knowledge.

I heard this morning a guy with door experience tell an anecdote. He'd had to face a guy with a folded blade in his hand and managed to defuse it with a "in the time you open that I'll realign your face. Be a nice guy and close it."

From now on I'm guessing. I'm guessing he wasn't bluffing, but believing what he said. Certain kinds of knife are not much known, here. Yet?

An assisted blade from a good source costs 35€ at the local Amazon. The legality of assisteds hasn't been explored in Spain, with a Weapons Code that predates their invention. A good "flipper" blade is about as fast. A BAD thumbhole folder is just as fast, since it becomes, basically, a gravity knife.

And on and on.

Is your reaction faster than that? In bad light?

What other things are you so sure about?

Take care.
