Accordion Wire
From Warhammer 40k - Lexicanum
Accordion Wire, also referred to as Razorwire, is a staple of trench warfare. It comes in wickedly barbed metal spools that can be quickly stretched out and deployed to defend trenches or buildings from an infantry assault. Crossing without injury or entanglement requires a great deal of dexterity.[1][2]
