FOUR EXAMPLES OF SCRAPERS
& POSSIBLE ADZES
EASTER ISLAND

   Obsidian was also used to make scrapers, drills and

other tools. The sharpest cutting edge can be obtained

from obsidian. But the edge is fragile and will not hold

up well. The harder basalt will make longer lasting wood

cutting tools and in fact most of the adzes described by

William Mulloy were of either that material or andesites.
The tools in this picture are made of both obsidian and

the harder andesite.
