A titanium drinking item that goes by the name vampire straw flashed a tooth sharp enough to get its owner arrested by Massachusetts State Police on charges of carrying a dangerous weapon.

As opposed to round-ended metal straws, the vampire straw has a sharp end.

“Designed for self defense, the vampire straw is super tough and long enough to be used like a dagger; its chiseled tip is sharp enough to puncture most synthetic materials,” Szabo writes in the item’s description.
