Types of Filing Tools and Their Uses

A filing tool doesn’t just smooth out the rough surfaces and edges, it also shapes, trims and creates a surface area. 

Files are used in an array of artisanal, professional and even craft industries. Metal smiths, jewelry designers use files to create and shape their creations. Woodworkers, carpenters use them to shape, smooth and sculpt wood and wooden details. Files are an artist’s tool, a woodworker's tool and a craft tool

Not just for smoothing, many DIYers and professionals will tell you that when gluing two items together, it’s recommended to rough up the surfaces before applying glue to them so that they stick and hold better.
