Gilded steel pickaxe

The Gilded steel pickaxe is a decorative steel pickaxe that has been gilded by the Liquid Gold Nymph. If a player has been awarded all of the pieces of the golden mining suit, when the nymph appears she will offer the player Mining experience or she will gild any one of the pickaxes a player has in their inventory. Foreman Jaak can remove the gilding from any pickaxe if asked. Gilded pickaxes are merely cosmetic and provide no additional bonuses.

When the Nymph appears, you will be given the option to gild the pick in your inventory or toolbelt, essentially signaling that it is possible to add any gilded pick to the toolbelt.
