That’s one killer Christmas tree.

Officials at a Lithuanian airport had an unusual take on the festive holiday tradition — a massive tree made up entirely of dicey items confiscated from travelers.

The base of the tree at Vilnius Airport is made from scissors, while the treacherous timber is decorated with a fake gun, bullets and brass knuckles — and topped with a star made of blades.

The unusual display was billed as an educational tool for holiday travelers.

“With knives, scissors, lighters, blades and all other sorts of dangerous goods on it — this Christmas tree has it all,” Lithuanian Airports said in a post on linkedin.com.

“So if you don’t want your personal, yet prohibited, belongings to land on our next year’s Christmas tree, better check out the baggage requirements before you pack for your next flight,” the post said. “Safe travels!”
