Mayas did not use metal tools because metals were not common to the area
that they inhabited. The tools that they had to work with were very
simple. They used tools such as fire and basalt axes on wood.
Fire was very unpredictable so they switched to basalt axes for a little
more precision. On stone they used tools made of flint, obsidian,
granite, limestone, and quartzite(Stierlin 132). They also used the
technology of the "plumb bob" to judge vertical accuracy(Stierlin 131).
A heavy weightwould hang on a string so that they could see how accurate
they were(Neufeldt 452).
built their structures without the help of the plumb bob and did not roll
heavy stones on logs as the Mayans did. For more information see
