Should we use mini pizza wheels instead of knives to eat pizza?

When you order a pizza, they'll usually run a large pizza wheel over it to cut it into triangles. We then sit with our knives and forks to eat it.

But why are we using traditional cutlery? If knife isn't suitable to trianglize the pizza why is it suitable to eat one?

Wouldn't it be better if we had a smaller version of the pizza wheel we could hold like a knife?

Thoughts?
