This chant magically enhances and maintains the sharpness of a single edged weapon, which must be kept on the anvil for the entire duration of the spell's casting. However, the spell does not provide any other benefit; the weapon can still rust, break, pit, crack, and melt, and eversharp chants do not grant any bonuses to attack or damage rolls. Once protected, the weapon need never be sharpened.
The material component is a pin made of silver (10 gp value).
