Who would have believed that Tullio Campagnolo, goliath of the cycle industry, personal friend of Eddy Merckx and donator of a groupset to Pope John Paul II, would also be the inventor of the ubiquitous two-armed corkscrew?

Campagnolo corkscrews, of massive size, manufactured to highest precision, crafted from the finest materials and, most importantly, presented in their signature wooden boxes, are avidly collected by cyclists everywhere.

Somehow the Park Pizza Cutter doesn't have the same cachet.
