Cabinet Handle Pull

Do buttons go on drawers or cabinet doors?
Knobs and handles. I can not understand. I think the buttons are on the doors cabinets and pull handles on drawers go. But I could wrong, it could be the reverse. Or maybe it does not matter. What is your opinion? Can you justify?
It's really a personal preference, but most say … knobs on cabinet doors and pulls on the drawers. But I've seen in both directions. It is best to get the buttons and knobs you want, then hold them until drawers and cupboards and see what you like.
