Ahh with spring comes the cutting threads.
I rarely ever cut and when I do it because others in the clutch have pipped. For the reasons Robin mentioned I want to make sure someone isn't trapped in an egg, which has never been the case.
Everyone does their own thing but I dont see the benefit of cutting a bacteria free sealed egg prior to the snakes use and need of it. I dont want to deal with mold or bacteria or be concerned its drying out or the fluid has turned to smelly muck. I am too busy for that stuff. I have hundreds of animals to look after (plus two jobs, family) and I am not interested in having to take care of any that havent even got out of the egg yet!
So no Edward Scissor Hands here.
I have many friends that are cutters but thats not how I roll.
To each there own.
