lastchance, this is two different things. Forged refers to how the hook is actually made, forging means the hook is hammered into shape as opposed to bending or molding. Forging makes a stronger hook for the same weight of material and it will be slightly smaller. Chemically sharpened means a chemical process is used to sharpen the hook instead of the usual method of using a grinding wheel to sharpen the hook, Two different processes to achieve two different goals. Take care, John
