scissors gotta do right handed or the pressure is wrong for cutting it seems like

Yeah that's exactly it. Your hands don't actually cut by pressing totally up and down. There's a slight lateral motion which, when using scissors in the hand they're designed for, pushes the blades away from each other where you're holding them, which has the effect of pushing them into each other on the other side of the pivot point.

When I eat I use both hands

Eating right-handed means the knife is in the right hand, fork in the left.

Outside of knife-and-fork eating, the spoon goes in the dominant hand, unless doing the spoon + chopsticks you get with some noodle soups, in which case chopsticks are in the dominant hand and spoon in the secondary hand.
