Sorry, I don't buy this theory of people being "scared" of knives. I've pulled out karambits, I've pulled out big 5 inch bladed Cold Steel Voyagers, pulled out automatics, you know how many people were upset or scared by them? Not a one.
Perhaps we live in different places with different social norms. Or perhaps I'm more sensitive to how people are reacting around me and notice more. You don't have to buy that, or anything. I'm just noting, that for me, most traditionals create less social friction.
And I CAN open an Opinel or Sodbuster one handed, as long as I'm paying attention and being careful, but it's nowhere NEAR as easy OR as safe as, oh, literally ANY KNIFE with a thumbstud, flipper, or opening hole, not even freaking CLOSE.
If you can't open an Opinel or Sodbuster one handed safely, then perhaps you should stick to those safety scissors with the rounded tips. More likely, you are younger than I am by a matter of several decades and the fact that you never have gotten comfortable with traditionals makes them feel unsafe to you. <shrug> That's just your inexperience showing.
BTW, friction folders (Iike the Opinel) and slip joints (like the Sodbuster) are much safer and easier to CLOSE one handed.
