Shovel
The Shovel is a common tool found in construction sites and is the common tool of treasure hunters searching for Rupees and other valuables underneath the soil, but also to find hidden passages. Link used this tool many a time to collect Rupees for his own use, although he was able to help some people find treasure such as a Flute that had been lost by their owner. It was first seen in A Link to the Past and appeared later in Link's Awakening, Oracle of Ages and Oracle of Seasons.
