Saw
A saw was a tool with a serrated edge to cut through softer materials. The material left behind after sawing through wood was called sawdust. 

In 2370, after her encounter with a Bajoran Orb, Major Kira Nerys told Vedek Bareil Antos that all she saw was "lots of hammers, s, and saws, surrounded by lots of Vedeks," when in actual fact her vision was much different. ()
