With a saw file, practice, and a little instruction you can keep your saws cutting swift and straight, and turn any flea market find into a gem.
Our range of Corradi saw files will work for Western Saws from 6 TPI to 15 TPI. The Corradi needle file will be perfect for 15 TPI and finer saws. We particularly like the Corradi files for their geometry - they have small arrises (the flat spot at the tip of each edge, think of a triangle with the top knocked off), which equates to more control over the size of your gullets. With a large arris it is easier to gouge out the gullets and shrink your teeth. Corradi Saw Files allow for much more careful sharpening, especially with higher TPI saws.
Note: If you are looking to sharpen a larger backsaw or our own BT&C Hardware Store Saw, Corradi’s Three Square File (CO-SQFILE) produces the best result. Three Square Files have the smallest arrises, and being second cut, cut finer and better on thin plate saws. The narrow arrises mean deeper gullets and faster sawing.
You should always fit a file to a handle for proper use; saw files have different tangs than regular files and therefore do not correspond with the usual handle size recommendations. Nearly all of our saw files use a #3 Skroo-zon handle, the 7" slim uses a #4 (see below for the link). The Needle File Handle does not match a Skroo-zon handle but rather a plastic handle made by Corradi called "Handle for Needle Files and Other Small Shafted Items" linked below.
