How to repair a kitchen knife with a broken tip (tip)

If you handle the knife carelessly, you can damage and even break off its tip. As a result, the cutting object loses not only its visual appeal, but also some of its important functions. It becomes not very convenient for them to work and not very productive. This shortcoming can be corrected by having readily available and inexpensive tools and materials at hand.

Recovery process


Let's choose a method for restoring the knife edge. You can remove the metal from the blade side. It is thin and there will be significantly less work. But then you will have to re-align the cutting edge, which only an experienced craftsman can do.
We settled on the option of removing metal only from the back of the blade. Of course, here the metal is thicker and therefore the volume of metal removed is greater, but you won’t have to deal with restoring the blade of the knife.
To do this, use a black marker to shade that part of the metal of the knife that we are going to remove and get the tip of the blade.

Using a cutting disc attached to the spindle of a mini-drill, we remove the shaded strip of metal on the blade. In this case, the spindle speed should be average so as not to overheat and release the metal of the blade.

Using the same drill, we process the modified back of the blade at 3000 rpm with various attachments in the following sequence:
  • high-grit grinding wheel;
  • low-grit grinding wheel;
  • wire polishing disc;
  • synthetic polishing wheel;
  • felt polishing wheel, with a small portion of polishing paste pre-applied to it (GOI, Dialux, etc.).

All that remains is to sharpen the knife blade, using successively a sharpening stone with two sides of different grain sizes and grinding stone in the form of a round or oval steel rod with longitudinal notches.
