The ax is simply indispensable to the owner of a private house, but the tool will serve effectively, if only it is sharpened correctly. The material for the working surface of the ax is tool steel, which contains more than 0.7% carbon. Sharpening an ax can be done by several methods, regardless of which metal is in the composition of the piercing part.

Features sharpening an ax
Before starting work it is recommended to prepare a template, for this you should use a piece of tin or other identical material. It is necessary to determine the angle of sharpening, equip the corresponding cutout, place the template on the tool blade. The marker allows you to put on the surface of the blade the desired mark.
You can sharpen an ax correctly only if you know what purpose it will be used for. Among the factors that will influence the process can be identified: the hardness of the wood with which to work; material moisture index; the nature of the work carried out with the help of a tool (chopping wood or scaling); type of blade base.
Drawing of an ax blade.
The angle of sharpening is regulated by state standards, if the ax is supposed to be used in construction, the angle should be between 20 and 30 °, while the angle of sharpening of a carpentry tool should be 35 °. These parameters are averaged.
A smaller sharpening angle indicates a sharper blade. This ensures that less effort is required to make work. But an ax that has a sharper sharpening angle will dull faster. In addition, the working surface of such an ax with greater certainty will be linked in the material, it will entail the need to make additional efforts in order to extract it. To work with logs and small trees, heavy tools should be used, the sharpening angle of which ranges from 35 to 40 °.
In order to give the tool the ability to effectively cut logs and cut large trees, the blade should be sharpened at an angle of 25 to 30 °.Back to table of contents
Sharpening tool with electric sharpener
To return the sharpness of the ax, you can use electric sharpening, a tool that is represented by an abrasive wheel with the ability to rotate quickly.
Four common forms of sharpening an ax blade.
In order to sharpen an ax by means of an electric sharpener, it is necessary to prepare:
- electric sharpening;
- grinding double-faced stone;
- lapping paste;
- installation to correct the abrasive wheel;
- permanent marker;
- protective equipment at work;
To begin with, the machine should be placed on a horizontal, reliable base. The working surface of the installation must be analyzed for the absence of irregularities and all sorts of small notches. If any were found, then you can get rid of them using the method of using a double-faced stone, it will allow you to correct the grinding wheel by eliminating irregularities. In order to update the sharpening, leaving the same angle, the surface should be covered with a marker.
At the next stage, it is necessary to fix the tool, placing it opposite the surface of the grinder. Its location should be such that the circle rotates towards. Now you can lower the blade to the abrasive surface. The sharpening angle needs to be corrected and strengthened using a special nut. Two turns need to be made independently, directing a surface on itself. The tool can be detached, which will allow to analyze the resulting slice under black paint. If the slope was selected correctly, the shaded surface will be erased. Provided that the angle is too small, only the end of the black blade will be erased. The stage must be repeated until the sharpening angle is accurate.
The pattern of formation of the burr on the ax blade.
As soon as the correct angle of sharpening has been achieved, the tool can be finally strengthened to carry out the work. It is necessary to perform sharpening until the elimination of chinks from the blade base. Next, you need to create a new line of cut. The abrasive wheel should be smoothed using a two-sided stone. Sharpen the need to bring to a perfect smooth cut. The tool must be firmly held and from time to time to turn one or the other side. This will ensure uniform sharpening.
After carrying out the above actions, the tool must be released and applied to the leather circle sharpening a finishing paste. Holding the blade at an angle of 45 ° relative to the machine, the grinding should be polished. The working surface of the ax should be moved smoothly. In this way it will be possible to grind chamfers. It is possible to protect a tool from rust after sharpening using a special tool.
Once the work is completed, the base of the abrasive wheel should be leveled with a stone.
If the sharpening process involves changing the initial angle, then it is necessary to use a goniometer at the same time, this will allow you to set the turning angle correctly. From time to time the surface of the abrasive wheel should be wetted, this will reduce the temperature. The blade should be immersed in a container filled with water after each pass. This will not only lower the temperature of the blade, but also extend its life.Back to table of contents
Hand sharpening technology
Scheme manual sharpening an ax.
Sharpening an ax can be done with an abrasive wheel. This method can be considered the most simple and common among home craftsmen. To do this, you need to strengthen the tool between wooden squares. Fix the abrasive bar at the required angle. The blade must be held vertically and led them in a horizontal plane.
There is another way to sharpen an ax yourself, for this you have to prepare:
- steel brush;
- rust inhibiting compound;
- protective glasses;
- blade polishing paste;
- protective gloves;
- work surface with clip;
- brush to get rid of metallic dust;
- bilateral stone;
- machine oil;
The working surface of the tool should be free of rust, for this you can use a cleaning agent, as well as steel wool. The blade must be treated with coarse sandpaper, sanding must be done over the entire surface, and sandpaper must be moved in one direction. Now you need to repeat these works, applying a sandpaper of lesser rigidity. On the rags need to apply a polishing paste and handle the tool.
The ax should be laid on the edge of the desktop, with the handle should be on the ground, while the blade area will go beyond the edge. Alternatively, an ax can be strengthened using a vice. With the broom file you need to process the blade. With correct sharpening, the blade should have a maximum width of 12-13 cm, which is equivalent to 25 ° when combining visual lines from the edges. The brush will help get rid of steel dust. Now, for sharpening, you should use a two-sided stone, which you need to move with arc movements. Before this, the stone, depending on the type of material in its base, must be oiled or moistened with water. Liquid will get rid of sawdust.
The same method should be used when sharpening from two sides using the less hard side of the stone. In conclusion, you need to apply a protective mixture that will eliminate the appearance of rust.Back to table of contents
When used for electric ground sharpening, you should choose the lowest speed. This will reduce the impact of the blade on the circle to a minimum. It is not recommended for these purposes to use the grinder. This is due to the fact that the pressure and high temperature contribute to lowering the quality of the blade. After completion of work on the surface of the blade need to apply lube and wax.
You should not neglect safety measures during the work - it is surely recommended to use goggles and gloves. When working with a two-sided tool, one of them should be sharpened. You can use the tool when working with coarse wood.
If there are not enough skills and tools for sharpening an ax, it is recommended to resort to the help of a specialist.
