Now it’s convenient to sharpen knives: how to make a simple sharpening device

Working with a dull knife is difficult and dangerous. If it slips off the material, it can injure your fingers. Manual editing requires experience, as it is difficult to maintain the sharpening angle along the length of the blade. Good devices for this purpose cost several thousand rubles. Fortunately, it is possible to do it yourself. To do this, it is enough to have metalworking and welding skills.

Will need


Work on a homemade product begins with the preparation of the following materials and products:
  • two sections of square pipes of different sections;
  • two steel plates of equal width but different lengths;
  • pairs of identical rectangular strips of steel;
  • two different pairs of bolts and nuts;
  • U-shaped blank from steel strip;
  • rubber strips;
  • glue for gluing rubber to metal;
  • a can of aerosol paint.

In your work you will also have to use a vice, welding machine, grinder, drill and scissors.

Fixture manufacturing process


The sharpening angle of knives depends on their purpose.We will focus on home kitchen knives, for which it is 25-30 degrees. First, we cut off the required length of the square pipe and form a cut at one end at an angle of 25-30 degrees.

We form a steel plate of the appropriate dimensions and weld it along the contour to the inclined section of the square pipe.

We clean the seams with a grinder and remove metal deposits. We make the surface of the inclined plate smooth, and the contours without nicks or irregularities.

In two small rectangular plates, moving away from one end along the length, we drill holes. We round the corners of the plates above the holes. We weld them vertically to the short plane of the square pipe connected to the inclined end, slightly retreating from the other end and the side edges. Moreover, the holes should be on top.

In a square pipe of a smaller cross-section, we drill through holes in the opposite edges in the center, slightly moving away from the end. We also form the second end of the pipe at an angle of 25-30 degrees, using a grinder.
We place a smaller pipe between the “ears”, and using a suitable bolt and nut, connect them so that the smaller pipe can rotate freely around the bolt.

We weld a steel plate to the inclined plane of the end of the smaller pipe, which would completely cover the lower one in width and length.

We drill a larger hole in the top of the U-shaped plate and weld a nut of the required size under a bolt of the required length. We weld the legs of the resulting structure vertically to the larger square pipe so that the smaller square pipe is between them.

For beauty and protection, we paint the device from an aerosol can. We glue strips of rubber to the mating inclined plates, covering their dimensions with a margin.

After the glue has hardened, use scissors to cut off the excess rubber protruding beyond the contours of the plates.

We clamp the base of the homemade product in a vice. We place the butt of the knife blade between the plates and secure it with a bolt in the U-shaped plate. Now the knife can be sharpened or edited without fear of disturbing the sharpening angle.

    I thought there would be a device on which you could actually sharpen, but here such a lot of work is put into making essentially an ordinary vice, which almost everyone already has. But the welding machine and welding skill required to make this crafts, few have.

    So much work for a regular vice. And at the same time, sharpen while holding the grinder in weight.Where will the angle be observed?
