"Your first parry move doubles as a damaging axe attack."

Whetstone is a charm available in Porkrind's Emporium at a cost of three coins. When equipped, it allows the player to use parries to deal damage to enemies.

Using the whetstone to attack is identical to performing a parry, but it can be used on nearly any enemy or boss. The actual attack can only use once before the player has to land; all subsequent parries act as normal, non-damaging parries. This does not apply to airplane levels, such as Threatenin' Zeppelin, as the player has no ground to land on.
