Handy files are machinist’s files that resemble hand files in appearance, but their unique tooth configuration means that you can use one tool for both rough, rapid filing and finer finishing work.
Their versatility makes them useful for DIY tasks around the home. For this reason, they are also known as homeowner’s files.
What are the characteristics of a handy file?
Cross section and profile
Handy files are blunt, and rectangular in cross section.
Cut
They are cut on both faces and on one edge. However, the defining feature of a handy file is that they are cut differently on both sides! One side is coarse and double cut, the other is smooth and single cut.
This prevents DIYers from having to carry two files around and saves space in the tool box.
Size
Handy files are usually 200mm (8 inches) long.
Swiss or American?
Handy files are American pattern files.
Handy file variations
Some handy files are curve cut on one side and shear cut on the other.
These files perform exactly the same function as other handy files, but are suitable for use on soft metals such as lead and aluminium, and resistant to clogging.
Rather than being double cut on one face, farmer’s own files are single cut on both faces, but coarser on one side of the file than the other. This suits them to sharpening a wide range of gardening tools.
