Pictured is a sharpening system that can easily be assembled in a hardware store for less than the price of one of the Gransfors Bruks tools. Not as compact as the Gransfors tools but no less efficient. It consists of
A coarse crosscut file
A fine metal file
A set of diamond hones (these are an alternative to the fine metal file)
A sanding block
A block of buffing compound |

In addition to these tools, a variety of grades of “Wet and Dry” abrasive paper and some scrap leather will be needed. |
The Stages of Sharpening
There are four stages to the sharpening process. If you axe is blunt, you can omit stage 1, if just a little dull stages 1 & 2 can be omitted etc. The stages are as follows:

Step 1 - Cutting Back
This stage removes a lot of metal from the axe. It is used to “cut back” the bit away from a damaged area or “ding” where a dent in the cutting area has occurred. It is not necessary to remove every tiny nick from your axe blade. Indeed doing so will wear your axe down prematurely. However, periodically damage becomes so pronounced or an individual ding is so severe that cutting back becomes necessary.
The other occasion where I find it necessary to cut back is often when purchasing a new axe.
On the photograph above, you can see that the heel of the blade (A) is blunt and rounded compared to the toe (C). There are flat areas on the bevel (B) and the ramp (D). These flat areas will detract from cutting efficiency and trap dirt and sap promoting rust. A little cutting back will correct these problems and improve the utility of the axe.
So, how do we cut back. Well the tool we use is the axe file in the Gransfors Bruks system or the crosscut file in the assembled system.
What we need to do is file backwards, from the bit of the axe towards the poll. If we file forwards, we'll "push" metal towards the cutting edge forming a wire that will block cutting efficiency. Sadly this means we are pushing towards the cutting edge. GLOVES.
When we file, because we are using a coarse file, we'll leave grooves in the metal. These are tricky to get rid of later so we'll file bit to poll but on an angle (toe to heel). At the next stage we'll reverse the angle and this will get rid of the file marks. |

Some things are hard to photograph so I’ll need to draw diagrams. I’ll use an overlay of an axe that looks like this to illustrate the required actions |

This is the desired motion - imagine the green bar as the file.
However if that’s all you do, you will file the bit flat, and that’s not what we want, so lift your hand holding the file as you push and roll the file around the convex bevel.
