Grobet Round Parallel Files are similar to standard round files, but instead of tapering to a point at the tip, these parallel files have a consistent diameter along the entire length of the cutting surface. The surface is double cut. Sometimes referred to as "joint files", these specialized files are perfect for filing seats for hinge knuckles.

The lengths listed in the table below are the lengths of the cut portions of the files.
