How to sharpen a knife grinder? 2 simple method

The best way to sharpen the knife grinder, is to sharpen it on the surface grinder, but if you do not have such a machine, you can use other methods. Today I'll show you two easy ways how to sharpen a knife grinder and in the end you can see the video detailing the process of sharpening.

1. Sharpening on sandpaper

mincing knife can be sharpened to a fine-grained (P240 - P400) sandpaper. Put sandpaper on a very smooth surface (surface to be an ideal piece of thick glass) and fix it. In his case, I secured the sandpaper on the glass with masking tape.

Then a little sandpaper moistened with plain water, putting a knife tightly and begin to sharpen the movements in the form of eight. It should periodically rotate the knife 30 - 60 degrees. Thus the blade edge not lying around and sharpening will be uniform. Sand takes about 5 - 15 minutes (depending on the state of the blade) cutting surface to a shine.

In the same manner necessary to align the grating surface. The grille is already possible to grind in a circle (both clockwise and counter-clockwise), rather than writing out eight.

After closure of sharpening the knife and the lattice should adhere to each other as magnetized.

2. Grinding wheels knife sharpener grinder

The second method is even more simple. Virtually any hardware store sold special grinding wheels for grinding and grating blade grinder. Their value is only 15 - 20 rubles.

To sharpen the knife, you need to insert it in a meat grinder, then, instead of lattice insert grinding wheel and tighten the clamping nut, but not too tightly.

After that, begin to rotate clockwise. Thus the knife is sharpened very quickly.

To align the grille, hold the same operation, just insert the grinding wheel has instead of a knife. In this case, the handle can be rotated in any direction.

For best results, these two methods can be combined with each other. First and sharpen the knife grid with abrasive wheels, and then bring them to the P400 grit sandpaper (nulevka) to full brightness.
