The fuller, also known as the blood groove, is a furrow that travels down the length of the blade from the hilt to just before the tip, designed to reduce the weight of the blade and increase its strength. This allows the craftsman to create a lighter blade without diminishing the strength of the weapon, a process difficult to perfect but, when successful, produces a weapon both strong and light. The fuller reduces weight of the weapon by 20%, or 1/2 pound, whichever is greater, and increase the Hardness by +2. Restriction: May only be applied to swords.
