The kitchen knife is not fast. If you have a grindstone at home, you can use it directly. If you don't have a grindstone, you can use the magnetic plate at home to sharpen the knife. Here are the specific steps.

Required materials: magnetic plate, salt, white vinegar, toothpaste.

Step 1: Invert the plate made of magnetic material on the desktop.

Step 2: Apply toothpaste around the bottom of the plate.

Step 3: Pour in a little edible salt.

Step 4: Add a little white vinegar.

Step 5: Stir by hand to mix white vinegar and edible salt.

Step 6: Stick the mixed liquid at the bottom of the plate on the knife surface, and stick a little on both sides.

Step 7: Sharpen the knife in one direction along the protruding edge of the bottom of the dish.

Step 8: After grinding the reverse side, continue to grind the other side.

Step 9: Wipe both sides with a clean handkerchief after grinding.
