cultrivorous
adj. devouring knives

In June 1799, having watched a French mountebank pretend to swallow clasped knives, 23-year-old American sailor John Cummings boasted that he could do the same, and “after drinking freely” he proceeded to swallow his own pocketknife and three others offered by his friends.

Thus began a memorable career. According to George Budd in the Medical Times & Gazette, Cummings recounted his exploit in Boston six years later and was immediately challenged to repeat it. He swallowed six more knives, and an additional eight the following morning, “so that he had swallowed a knife for every day that the month was old.”

Nine months later, again inebriated, he made the same boast in England and swallowed five knives on Dec. 4 and nine clasp knives on Dec. 5 (plus, he was told, another four that he was too drunk to remember).

Through the next four years, in great pain and continually vomiting, Cummings applied to a number of doctors, at least one of whom dismissed his story as incredible. But when he died finally in March 1809, his stomach was opened and “a great many portions of blades, knife-springs, and handles were found in it, and were carefully collected for the museum at Guy’s Hospital, in which they are now preserved,” Budd notes — Cummings’ contribution to medical science.
