A crafting table/tab that turns Carl's shaped scrap into true equippable gear — the key to Katia's absorbable mass.
The Armorer's Workshop is a craft-table tab Carl buys with his last free table coupon at station 281 (also upgrading his Sapper's table to level three). Its function, confirmed by the Cookbook, solves a crucial problem: an engineering table can shape metal into helmet-like objects, but the system won't recognize them as true equippable gear. Running a shaped item through the Armorer's Workshop retitles it (Carl's first is a 'Shitty Helmet') and resizes it to fit, making it genuinely equippable.
This matters enormously for Katia-Grim, whose doppelganger mass can only absorb items she can actually equip — enabling the Ugly-Ass-Backpack super-tank technique. Carl can't yet enchant or use exotic metals, but can craft sellable scrap gear.
The crafting capability that makes shaped scrap equippable — the enabler of Katia's absorbable armor.
