Harvesting and peeling true Ceylon cinnamon (Cinnamomum verum) requires specialized traditional tools, notably the Vettakeeri (a small, curved brass peeling knife). Unlike carbon steel blades that react chemically with natural plant tannins and organic acids present in cinnamon bark sap (causing dark black oxidation stains that ruin the golden-brown appearance of export quills), brass is a non-reactive copper-zinc alloy. Using a brass knife ensures the scraped sub-cambium bark remains spotless and pristine, preserving top-grade Alba and C5 export classifications.
Peelers sharpen their brass Vettakeeri blades daily using fine river abrasive stones to maintain razor-thin slicing precision.
Traditional peeling knowledge is passed down across multi-generational farming families in southern districts like Matara and Galle.
Visitors touring southern spice plantations can examine authentic brass Vettakeeri tools during live peeling demonstrations.
