OXO Good Grips Gripe

Does anyone really believe that these giant, rounded grips make things easier to hold? What am I six years old? Our fingers benefits from having a surface or angle to anchor on not something rounded that will slip around. You ever try to use one of those shower brushes with the end that looks like an egg? Impossible. There's also this knife advertised on TV that has a ball on the top of the blade that supposedly helps you steady the knife. Guaranteed you'll slip off the ball because balls don't have anchor points. Give me stuff I can grip instead of rounded stuff, is that too much to ask for?
