But why would you want to cut them? It's more work and less bread.

It's the exact same amount of bread except some minimal residual loses from the friction of the cutting act.
Triangles also look more appealing as they look easier to eat.

So you cut the slice diagonally, so that you have 2 triangels per slice?
