The Javelin That Bent On Purpose And Voided The Return Policy.

The Roman legion built an entire market around a throw it never intended to get back. The pilum, the heavy javelin each legionary carried into battle alongside his short sword, was designed from the head down to fail after a single use, and the desk regards that intentional failure as its whole genius.
The specifications are modest and precise. The weapon ran about two metres overall: a wooden shaft joined to a slender iron shank roughly sixty centimetres long and only about seven millimetres thick, tipped with a small pyramidal point. A legionary typically carried two, one heavier and one lighter, and threw them in the last moments before the lines closed to sword range.
Thrown at short distance, the narrow point and concentrated weight punched through shields and armor. That alone would have justified the filing. But the design went further, and this is where the desk leans in.
The long soft-iron shank was made to bend on impact. A pilum lodged in an enemy shield did not simply stick; its shank crumpled, so the weapon could not be pulled free and thrown back, and could not be cleared from the shield without discarding the shield itself. The counterparty was left holding a ruined board or an unshielded body.
It was built to break the instant it landed, so no one could ever file it back.
Tradition credits the reformer Marius with sharpening the effect by replacing one of the two rivets fixing shank to shaft with a wooden pin, so the head would snap sideways on contact. Whether the specific story holds, the design intent is not in doubt: this was governed force with the return policy deliberately voided.
The desk finds the economics almost elegant. Most missile weapons on file are assets you hope to recover; arrows are gathered, stones are re-slung. The pilum was booked as a total loss on release, its entire value realized at the moment of ground contact, its salvage value engineered down to zero on purpose.
Paired with the gladius that followed it, the pilum opened the transaction and the sword closed it. The legion did not throw to kill so much as to disarm, to strip the shield wall a breath before impact. It is one of the desk's clearest cases of a throw valued not for what it destroys but for what it denies.
Compliance verdict: A payload designed to bend, lodge, and never return. The desk certifies the pilum as governed force with self-voiding salvage rights and records, approvingly, that the only party ever able to re-file it was the legion that had thrown it in the first place.
