Spring

Spring is a tightly coiled length of tempered metal wire, shaped to store and release mechanical energy. Crafted from iron or similarly springy metal stock at a smithing station, the Spring is a deceptively simple component that underlies a surprising range of mechanical devices — any machine that needs tension, recoil, or cushioning relies on one.

Springs appear as components in mid-to-late game machinery, weapons with mechanical actions, and precision tools. They often appear alongside Gears and Chips in complex crafting recipes, representing the mechanical layer of the island's technology. Stockpiling Springs before tackling major crafting projects is a smart preparatory step.
