The tools are closest to the 93 mm alox line on the Victorinox. Because the Profis are all old their tools are also usually machined in old time style, not tumble polished, etc. Think old style, coarse, 93 mm SAKs wrapped in think soft but solid red plastic, with exposed brass rivets.
I had to get myself a few to taste. They are nice but I will stop here collecting them, I have enough.
One more closer pic to give a better idea of how the tools are made:
