Yeah italy's system's actually quite different from anything elsewhere. There are 2 different ratings for plugs and sockets.
10A have thin pins in the same spacing as a Europlug with the centre earth pin.
16A have thicker pins spaced further apart than a Europlug. You cannot insert a 16A plug into a 10A outlet but you can insert a 10A plug into either outlet.
Italian 16A plug
Pins diameter: 5mm spaced 26mm apart.
Italian 10A plug
Pins spaced 19mm apart 4mm diameter
For comparison: A CEE 7/7 plug (note the pins are spaced just like an italian 10A plug but are too fat to fit into an italian 10A socket and too close together to fit into a 16A socket) (not necessarily a bad thing as it prevents schuko plugs being used without a ground connection in italy!)
Finally: an open rewirable italian 16A plug. note the pins are quite a bit thicker than schuko.
