I consider any person who judges me by the color of my knife to be an IDIOT. And I don't care what idiots think about anything.
I don't know how many times I've read on this forum about sheeple getting freaked-out by a SAK (polished blade, bright red handle, most non-threatening design imaginable).
I've been using knives in front of other people for over three decades, and I've been carrying a fixed-blade openly, in public, for about 7 years now. Despite all this, not a single person has ever freaked-out on me or called the cops on me.
I use my knives in a lawful and reasonable manner, I never try to be threatening or intimidating with them, I don't play with them in public (or private). But I also don't try to hide my knives, or their use, as if posessing or using a knife is something I should be ashamed of.
I bought one-hand opening folders specifically because I wanted folders that I could open quickly with one hand, and that's exactly how I open them.
I couldn't care less what people think about my knives, how I open them, or how I use them.
