What type of file should I use for sharpening an axe?

Coarse Sharpening and Pre-Sharpening

When sharpening an axe, it’s essential to start with a coarse-grit file, ideally between 24 and 36 grit. This type of file is designed to remove metal quickly and efficiently, making it perfect for pre-sharpening and coarse sharpening. The coarse grit helps to remove any existing sharpening imperfections, uneven edges, or rust, allowing you to work towards a precise edge.

Intermediate and Fine Sharpening

Once you’ve completed the coarse sharpening process, switch to a finer grit file, typically 60-80 grit. This grit level is ideal for intermediate sharpening, where you refine the edge and remove any remaining imperfections. Continue to work the file in a consistent, smooth motion along the length of the axe head, maintaining even pressure and avoiding excessive pressure on any single spot.

Techniques and Maintenance

To achieve the optimal sharpened edge, focus on maintaining a consistent angle and following the bevel of the axe head. For most axes, this is around 20-25 degrees. Additionally, keep your file flat and ensure it’s properly secured to a vice or other stabilizing device to prevent any movement during the sharpening process. Regular maintenance, including cleaning and lubricating the axe head, will also help maintain the sharpness and prolong the life of your axe.
