In the old days, I would have done this with a fine metal file, however since the advent of diamond files I prefer them. The Gransfors diamond file is great, but we showed the Gransfors tools last so here is one of the basic diamond hones
One of the things I like with these plastic backed diamond hones is that they can be flexed by pressing with the guiding index finger. This keeps more of the hone in contact with the bevel at once and preserves the convex grind.
Most diamond hones come in packs of three – coarse, medium and fine. It makes sense if you have all three to use them in that order. Use the coarse one in the direction indicated until all the file marks are removed. Then change back to the original (file) direction with the medium grit until all the scratches from the coarse grit are removed and finally reverse again with the fine grit. In theory these hones need to be wet to work, although I have used them dry and just rinsed them after use to stop them “clogging” and they worked fine.
Using the Gransfors system, you only have one grit available, so smooth out all the file marks in the direction indicated.

Step 3 – Sharpening

At this point, the techniques used in the two systems diverge. Lets look at the Gransfors system first. The axe stone has two sides – coarse and smooth. The axe stone needs to be wet to work. I carry some “water” in my mouth that seems to work quite well!
Wet the stone and put it onto the bevel. Move the stone in a spiral motion along the bevel from heel to toe. |

The water will build up a “paste” on the bevel. Avoid the temptation to remove this. The paste is the abrasive that will sharpen the axe
Use the coarse stone until all marks from the diamond file are removed.

To sharpen with the “assembled” system, we will use the sanding block.
These are the sanding blocks I like to use (they cost the princely sum of about £1.20). |

I like them because under the flaps that secure the paper are spikes that hold the paper firmly in place |

There is a problem though. If you wrap your wet and dry over something flat, you will make contact on a tiny area - like this
