Filing seems pretty simple.
However, Make points out theres a couple different methods to choose from.
You have two basic methods: straight filing and draw filing.
Straight-filing is typically used to rapidly remove material.
In draw-filing, the file is held on both ends and is pulled and pushed across the material crosswise.
Pick the right one, and youll get the results you want.
