Id like to share some tricks too. One that I really like is getting a lot of RPM while rotating your scissors like this, you face your palm to the sky and use your indicator as a hook to keep rotating, its really cool cuz if you slow down you lose to gravity and because of the same thing you can speed it up a a lot without it jumping out of your fingers
Try some custom methods, I personally prefer the middle finger as a stopper but sometimes your thumb can be used to close it while it's closing vertically
I just have a hairdresser scissors in home and I already hit my finders on the blade like 10 times, but is calm they don't hurt that much Oh yeah and I also ended up hurting my toe and blood accidentally went on my sock, it honestly felt like a tiny needle, but the pain went away in like 2 minutes
