FAIRBANKS, Alaska — The summer tourist season is about to arrive in Alaska, and the U.S. Transportation Security Administration is reminding passengers that a popular Eskimo-style, half-moon-shaped knife isn’t allowed in carry-on bags.

The Fairbanks Daily News-Miner reports that visitors to the state often forget that the knife, known as ulu, is banned like all other knives. The TSA has gone so far as to create special placards for the Fairbanks International Airport, displaying a picture of an ulu with a line through it.
