It was the unkindest cut of all.

A Brooklyn federal judge has awarded $10 million to the victim of a circumcision gone horribly wrong.

The money is to be paid by the maker of the Mogen clamp, a forceps-like device commonly used in circumcisions and shown in a medical journal to have been involved in other partial amputations.

Given that record, Magistrate Judge Marilyn Go found that a warning should have been included with each device. Instead, the instruction manual promised a risk-free procedure.
