By Trent Troop and Alex Androski.
A set of four makeshift weapons for action figures with 5mm peg-holes:
Licenses to Kill - A pair of punch-gauntlets, forged from crowbars, license plates and scrap-iron, for the right and left hands.
Engine Crasher - A v8 engine block ripped from its housing to serve as a flail. Comes on a length of functioning chain bolted to a 5mm piston-grip.
Ignoble Foe - The head of a fallen robot enemy made useful again through the addition of a smokestack-grip.
This set has been tested in white & flexible. Figures shown in the images are for display purposes only.
Update 2/15/13 - Updated hammer handle for more stability.
