Same family as the plain key and a clearly harder lock: the bow gains two lobes and four woven rings, the shaft is nine flats each rotated 18 degrees on the last so it reads as twisted metal, and the bit carries four wards of falling length plus two barbs on the far side. Bounding size 0.29 by 0.57 by 0.11 m; metres, +Y up, +Z forward. Origin: free, at the middle of the shaft, on the spin axis, because a collectible like this is hung in mid-air at whatever hover height the level needs and a base origin would put it on the floor. The geometry surrounds the origin, reaching 0.285 m below it and 0.285 m above it. Clips: bob (2.6 s), spin (2.2 s). Rigid node animation only: named nodes with translation, rotation and scale clips, no skinned rig and no skeleton. No collision volumes and no navigation data. Opaque materials throughout; the pack uses no alpha blending and no transmission.
