John,

You must have strong sharpened teeth like mine. Why not show them in the picture?

Jerry, "cut across the top" That's what I wanted to say! When I started writing at first, the picture of a crossword puzzle came up to my mind, but I couldn't recall the word. Across and Down. How could I write " cut in horizon way"? How far did I want to cut what? From US to Japan with scissors? Oh, no, the war has finished before we were born.

Yeah, it is the same as me. I noticed it was hard to write this. I mean, describing what you do with the hands is difficult. Opening the potato bag is easy but writing the scene is hard.

I open it with a blast using my hands only when I am inside my cave!:D

Gently, very gently to avoid potato chip confetti. If all else fails, I agree with Som, use scissors.
