Budget manual flipper knives that "quick open"

[raccoon]

@Macka17

That’s why I asked.
As we Physically, “flip”. The blades open with inside edge of thumb.
with both the Spidy and the side studs on blade?.

I do anyway.
Or is that called something else?.

Just because you can flip a knife open doesn't make the knife a flipper.

The knife has to have a flipper to be a flipper.

I know, it's quite confusing.
