Difference between blades and o-size?

I should already know this, but what is the difference? I'm looking at the i3's and really can't distinguish much.

I have a set of I3 blades. The difference between them is minimal but affect playability significantly.The I3 blades have a smaller head, narrower sole width, less offset and a higher centre of gravity.The blades allow you a little more workability where the O size are more of a game improvement club (higher and straighter, you know, the usual).Hope this helps, and if you decide on a set, whichever one, I think you'll be happy.
