A 56-year-old Tenderloin man is recovering today, after he was randomly stabbed by a man with a "very big sword," police say.

According to the San Francisco Police Department, the man was standing in front of his apartment building on the 400 block of Eddy Street, which is between Hyde and Leavenworth Streets, at 2:40 Wednesday morning when an unknown male suspect "walked up to him and stabbed him in the stomach with a sword," police say.

The LA Times reports that according to witnesses, "the attacker didn’t say a word" before stabbing his victim, and "there didn’t appear to be any particular motive for the attack."

SFPD spokesperson Officer Carlos Manfredi tells the Times that witnesses “don’t have any real description" of the errant blademaster, "just that it was a very big sword.”

“You get a lot of tweakers that get these swords … you’ll find a sword of some type at a flea market,” Manfredi told the Times.

“You get people high on drugs [and] they do random stuff like this. It doesn’t happen often, but it wouldn’t surprise me [to hear it.]”

The victim was rushed to San Francisco General Hospital for treatment of his injuries, and is expected to survive. As of Thursday, police say, the aspiring duelist remains at large.
