What do you expect when looking into a mirror? A crystal clear reflection of yours on a scratchless surface.

So, as the name implies, mirror polishing a knife means giving your knife a mirror-like shiny look without having any scratches or lines – so pristine that you can clearly see your reflection.

Mirror polishing demands a smooth and polished knife blade that you can achieve in two ways –

  • Mechanical polishing
  • Chemical polishing.

Mechanical polishing is a way to smooth and shine your knife by rough and fine-grinding the surface to remove rust and corrosion. It’s one of the common methods of polishing a knife.

On the other hand, the chemical method involves using fluids and solutions to remove oxides from the surface, giving it a shiny mirror-like look.

Whatever way you apply to sharpen and shine your knife, remember, a mirror finish requires absolutely no marks or scratches on the surface – perfectly smooth and transparent like a mirror.

Now that you have all the required materials in your hand, you are ready to begin the process. The following step-by-step guide will help to keep your blades looking shiny and new, no matter how often you use them.

Step 1: Wash The Knife

You need to wash it off to remove any foods stuck to the knife. You can just do the regular wash with dishwashing soap or liquid and rinse it.

However, you will need to dry the knife before proceeding to the next step.

Step 2: Grinding

If you are using the knife for a long time, it is normal to have an irregular and round surface on the blade. So, you need to make it smooth. You can do it by grinding using sandpaper or a sandpaper disk. In this step, we recommend using 120 grit sandpaper.

Step 3: Fine Grinding

If your knife has deeper scratches, you should grind more using hard density sandpaper. For example, you can use 1200 grit or more. Even you can move to the polishing wheel to make the knife smoother.

In this way, your knife is getting ready for a mirror finish. If you see any unwanted spots after grinding, you can use soft felt wheels.

Spending more time on fine grinding will reduce your job in the next step for fine polishing. So, use grease-based chemical compounds in this step to remove those unwanted spots.

Step 4: Polishing

This is the final step to getting a shiny polished knife. To get the ultimate outcome, use a stainless-steel polishing fluid. You can easily prepare by following some steps. Let’s take a look.

  • Take metal cleaning solution at 1:20 ration in a bowl and add hot water.
  • Next, add polishing fluid and stir it for around five minutes.
  • Then draw the knife into the mixture and keep it for a few seconds.
  • Wash with clean water.
  • Dry the knife.
  • Finally, apply Fabulustre and Zam to gain the mirror polish appearance.

Be sure that you handle your knife with protective gloves during the process. Also, use a mask to keep your face away from dust. These will keep you safe.

Depending on the knife, the process can take a few minutes to an evening. The more you do it, the easier it becomes. Mirror polishing a knife is fun and will make your knife look very artistic and beautiful.
