At first glance, this appears to be a simple whetstone, and can be used as such to keep weaponry in good condition. However, an apprentice’s whetstone makes weapons sharper than most. By spending 15 minutes sharpening a bladed weapon, the weapon gains a +1 bonus to damage rolls for the next 8 hours or until the weapon loses any hit points, whichever comes first. This effect works on both mundane and magical items. In addition, three times per day the user can press the whetstone to any item and speak a command word to repair it, as the spell mending. This effect always works on magic items, regardless of their caster level, and always restores its maximum amount of hit points (4).
