| 4 burren adze slugs | - Mogan Spring, NSW |  |
| 4 tula adzes | - Lake Eyre, SA |  |
The adzes in the collection are approximately 5cm in length. Therefore it is a small tool made from a flake produced from a prepared core.
There are two types of adzes within the collection - the burren and the tula. The difference between the two is the location of the working edge. On a burren adze (usually almost triangular in shape) the working edge is perpendicular to the striking platform. While on the tula adze the working edge is parallel to the striking platform. Also the tula adze characteristically has an obtuse angle between the striking platform and the bulb of percussion surface. When the adze becomes blunt, it is re-worked and with continuous modification and retouch eventually reulting in a step flaking.
When hafted a narrow strip of the working edge can be seen. Therefore the adzes could have been used for a variety of purposes mainly for wood working, for example - the cutting and shaping of bark and the shaping of wooden weapons, bowls and other objects, also used as ceremonial objects. The tula adze could also have been used in preparing animals for food. Therefore it is a very versatile tool. The burren adze would have been used for similar purposes as the tula adze. Like the eloueras the adzes were once hafted and were used as a chisel type tool. The adzes were particularly good for working with particularly hard woods.
When the tula and burren adzes have been re-worked to their limit, they are discarses and archaeologists have identified these as slugs, there are 4 burren slugs in the collection.
