I have the K model for Foil, and have something around a 10 sized hand. They seemed beefier in the lower prong than the Z model. The K and Z seem to me most like the Visconti. The B model did seem to be the biggest overall, but very different from Viscontis, I didn't like it. I was told by the person manning the vendor that the 1 are biggest , 2s are smaller and the 3 are smallest.
