• What you need

• This method is suitable for sharpening scissors that are not too blunt, but just a little sharper.
• Sandpaper also helps smooth out chipping and dents on the scissors.
• Some other materials you can use instead of sandpaper for your scissors are sandpaper and steel wool.

Wipe the scissors. Use a damp paper towel to wipe along the blade to remove any grime that may be on the blade as you cut through sandpaper. advertisement

Method 2 of 5: Grinding with aluminum foil

1. 

   
   
   Find an aluminum foil. Fold a sheet of aluminum foil about 20-25 cm long vertically several times to create a stack of aluminum foil that is thick in layers.
   • Laminated aluminum foil will help sharpen the blade many times after each cut.

2. 

   Cut the stack of aluminum foil. Use scissors to cut the entire stack of aluminum foil. Cut from the base of the scissors to the tip.
   • Depending on the width of the aluminum strip, you can either sharpen the blade as much as possible (by cutting many narrow strips) or just cut a few lines (by cutting a few wider strips).

3. 

   
   
   Prepare a grinding wheel. Place a towel under the grinding wheel and lubricate the stone with water or abrasive oil.
   • Stores often sell "grinding oil" in the same place as an abrasive, but you can use any type of oil, even water, to lubricate the abrasive.

4. 

   Sharpen the inner edge of the scissors. Place one scissors on the grinding wheel, the inside edge of the scissors (the flat inside the blade that is in contact with the object to be cut and facing the inside of the other scissors) is facing down. You need to create a correct and close angle between the inside of the scissors (the part you are grinding) and the cutting edge (top edge of the inside of the scissors). Where the junction of these two sides is adjacent is the part that needs to be sharp to cut. Grasp the blade handle and slowly slide the blade across the grinding wheel toward you, keeping the edge of the blade close to the grinding wheel.
   • Repeat this movement slowly and carefully until the blade is sharpened. Do this about 10-20 times.
   • Repeat with the other side.
   • You should practice with some old scissors until you are comfortable with sharpening the blades.

5. 

   
   
   Sharpening the cutting edge of the scissors. Grasp the handle of the scissor blade and lean forward until the cutting edge (the bevelled edge adjacent to the inside of the scissor) is flat on the grinding wheel. Adjust the angle as close as possible and continue to slide the blade forward. Repeat this movement until the blade is sharpened.
   • If you start to sharpen with the rough surface of the grinding wheel, you will need to sharpen a few more strokes on the smooth surface for a smoother pull.
   • If you have never had this type of scissors sharpening, it may be difficult to know when the edge of the scissors is completely sharp. Use this tip: before you start sharpening, paint an indelible brush line on the edge of the scissors. Start sharpening the scissors, and when the brush ink has worn off, you're done.

6. 

   Removes metal ledges on two scissors. When the sharpening is finished, you may notice a metallic rim along the sharp edges of the scissors. You will easily remove these burrs when you attach the two scissors together and open and pull a few times. Next, use scissors to cut certain materials such as paper, cardboard, or fabric to ensure that the metal edges on the scissors are blown away.
   • If the scissors are sharp, the sharpening job is done. If you want to make it sharper, repeat the process above.

7. 

   Cut into a glass jar. Pull the scissors to cut into the glass jar so that the vial slides out between the scissors. This is like cutting paper or fabric. Cut with light force and let the grinding glass pull for you.
   • Repeat this process until the edges of the scissors are smooth and sharp.
   • Be sure to use a glass jar that you don't regret if it gets damaged, as the scissors can leave scratches on the jar.

8. 

   Cut into the pin. Cut into the pin so that the nail slides between the scissors. This is like cutting paper or fabric. Cut with light force and let the sharpening nail pull for you.
   • Repeat this process until the edges of the scissors are smooth and sharp.

9. 

   Wipe the scissors. Use a damp paper towel to wipe the edges of the scissors to remove any metal that may stick when you cut the staples. advertisement
