I thought I would begin my third of a series of four livestock workshops at the University of Minnesota petting cute, cuddly lambs and kids (as in baby goats), but instead we started out sifting through a box of what looked like medieval torture instruments. The all-in-one castrator and tail docker, a clever little gizmo, was designed to cut off the relevant body part and simultaneously crimp the ends of the wound shut to prevent excessive bleeding. The hand shears, for clipping sheep destined for competitive shows, were more or less giant, extremely sharp scissors. My personal favorite was the hot-iron tail docker, most notable perhaps for its very low-tech-ness.
