Suppose it was a Fallkniven?

"[A] driver of a semi honked at the driver of a Mercedes because the car had blown through a red light in front of him and other traffic while the luxury car was getting onto 15th Avenue Northwest. But the guy in the Mercedes is apparently very sensitive about criticism, something that became obvious when both the car and the semi had to stop because the Ballard Bridge was up. That's when the man in the semi spotted the other fellow swearing at him in the mirror and allegedly waving a huge knife over his head.

[...] The trucker pulled over in the 1100 block of Elliott Ave. W. following instructions he got from police after calling 911 about the maniac in the Mercedes. But the guy in the car was still on his tail, stopped in traffic next to the truck, started swearing, waved the knife around again, and threatened to cut the trucker, according to the police report. The guy in the car also tried to circle back two more times in an effort to get at the trucker, but police had showed by the last attempt and pulled the road-rager over [...]. The man [was] booked for unlawful use of a weapon, and a container of eight chef's knives of various sizes was placed into evidence."
