Executioner's Whetstone

An Executioners Whetstone is a powerful sharpening stone. It makes a non blunt weapon unnaturally sharp and causes it to inflict far greater damage the next time it strikes a foe. Sharpening with the whetstone takes one hour and while it does improve the quality of the blade for about a week, it must be resharpened again for the full hour after each use in order to give the weapon its special first strike property.

For Blunt weapons there is a special hardening oil that achieves a similar effect known as executioner's oil.
