How to Polish a Knife: ( With Dremel, Household items)- Mirror Polish

The process of polishing your knife is very similar to sharpening your knife. The difference is that polishing involves rubbing the blade with abrasives to remove oxidation, while sharpening involves removing metal to create a new edge. The first step in polishing a knife is to separate the blade from the handle. That allows you to work on the blade with far less risk of scratching the handle. You should keep the pocket knife clean before every use. Knives are an essential part of a kitchen.

Cleaning Properly

Knives should always be clean and ready for use. If there is a mark, make sure to wash and dry it off using mild soap and a scrubbing pad. For more serious stains, toothpaste and abrasive scrubbing pads can help.

You need to clean your knives after every use. Some people like to use baking soda to buff the knife’s blade. Clean with a cotton swab and dry it off before storing it again. Proper storage is very important. Rinse off with warm water and lemon juice, then coat with penetrating oil to prevent corrosion.

Remove Rust

Rust is a formidable opponent. It can happen to any knife, but the newer the model, the less likely it will experience rust. But when it does, you are going to need to take action. There are two options for getting rid of rust: store-bought treatments or making your own.

Using Store-bought Super Safe Rust Remover

Getting rid of rust using rust remover can be tricky. There are several steps you need to take to prepare for this task. First, get a rust remover and put it in a bowl. Next, cover the knife blade with the rust remover. Then, place a cloth on top of the edge and wait 10 minutes. 

Abrasive cloth: A must things to note

Not all oils will work, and it’s essential to check and see what type of oil you have before putting it on the blade.  Now, take the blade out of the container. You can then clean any rust off with steel wool or a fresh cloth. If there are many oils on the blade, you can remove them with a polishing cloth.

Using Household Rust Remover

If you need to remove rust from a knife or other metal, household rust remover is a great way to go. Household rust remover is a combination of chemicals that help to dissolve rust and remove it from the surface.

Want to remove the rust from your knife? Here are five steps for a homemade rust remover:

  2. Rub the solution onto the rusty areas
  3. Scrub gently with an old toothbrush in circular motions
  4. You must clean the pocket knife with foamy water after you wipe away the rust

How can you polish knife blades by hand?

Polish a pocket knife blade by hand with these easy steps. Polish your knife like a pro after you learn the correct way to do it. The best thing about polishing a knife blade is that you can do it yourself, and it doesn’t cost much. All you need is a few supplies and a little practice, and you will be able to polish a knife blade like a pro.

If the individual steel grains aren’t noticeable, you may need to look at the metal surface to figure out how they’re running. The fastest way to do this is by hand in less than 10-15 minutes. However, if it’s excessively rusty or broken up, it may take longer to recover.

So, you’re using soap, water, and towels to clean your metal. Keep scrubbing! After that, polish the metal with a paper towel until it reaches that desired look. You can stop polishing or finish by applying more layers of the polished knife.

How can you polish your knife Blade with a Dremel?

Dremel rotary tools are used for cutting, sanding, polishing and carving. As a hobbyist, you can use this tool to create carvings and polishings the blade of a knife. To start this process, you will need the following:

  • Dremel
  • 1/2″ felt polishing wheel
  • Safety Goggles
  • Vise
  • Mandrel
  • Silicon Carbide Grinding Stones
  • Polishing compound

Here are three easy steps

  • Fasten your knife to the vise. You must tight the vise to ensure the pocket knife is held firmly but not too tight. 
  • Ensure that the workbench is stabilized when polishing your knife blade. 
  • Prevent accidents by tightening the vise enough to secure your workbench, but not too tight.
  • Attach the Dremel to the grinding part.
  • Fasten it securely so that it doesn’t hurry off when turned on.
  • To sharpen a blade, use a correct angle. For example, 12.5-degrees is one option for both sides of the blade or just one side with 24-degrees.
  • We recommend using the Dremel on the upper part of the blade. 
  • Never forget to let the knife blade wind down before doing the next pass on the opposite side. 
  • To polish the blade, use the felt pad, mandrel, and polishing compound.


European grit size isn’t as coarse as some other types of sandpaper, so you should first use a 1200P before going on to hone with a chrome polish.

How to mirror polish a knife by hand?

Knife mirror polishing is among the most advanced knife sharpening techniques, but it’s also the most rewarding. For that reason, you should brush up on your sharpening skills before attempting this advanced knife sharpening method.

Here are the eight easy steps to achieving a mirror-finish on a knife:

  1. Pick up a fine stone, paper, and chrome polish from the store.
  2. Get to work with the diamond side of the stone to flatten out all the micro hollows and bumps.
  3. Use the ceramic side of the polishing stone to remove the remaining grit marks from the diamond side.
  4. Once you’re finished, use a clean cloth to wipe off any leftover residue.
  5. Use a belt sander to make a ceramic form smoother.
  6. Add a final thin layer of white stones for a more pleasing finish.
  7. Clean the mirror polish with a paper towel or polishing cloth when it appears.
  8. Repeat the process until you reach your desired mirror-like surface on a knife blade.

How can you polish the deep scratches of the knife blade?

To minimize the deep scratches on your blade, first, ensure that the pocket blade is dry. With a dry clean cloth, you can dry out the knife before polishing. The rubbing compound will not be absorbed if it keeps coming into contact with moisture. You should use a paper towel to dry off the knife blade.

Cleaning your blade is simple. First, you need to scrape the knife lightly. Then, scratch through the rust with light pressure. Finally, polish it with a rough material like grit paper or baking soda. Make sure to clean not only the blade but also the base and handle. All the rusted areas are full of dirt and grime that you might not see because it is there. It is not always possible to give a mirror finish to the blade.

What is the best speed for buffing compounds? 1800 OR 3600 RPM?

There are differences in speeds when it comes to rotations, and they can make all the difference. It’s essential to remove material at the right points for an excellent finished product. The advantage of 1800 rpm is that it is less likely to cause friction and heat with faster rotations.

When you’re buffing, it’s essential to consider the speed of the buffer. For example, the 1800 rpm buffer is an excellent choice for smoothing down rough plastic and epoxy. It also prevents heat buildup and reduces friction. On the other hand, the 3600 rpm buffer is suitable for using greaseless compounds and can do a better job than the 1800 rpm when it comes to scrubbing.

Final Words

Once the blade is clean, make sure it’s scorched by running a thick, soft cloth over it. Next, lay the knife flat on a clean towel or microfiber cloth. Finally, apply your polishing pad on top of the blade and place the brass rod across the top of the two handles to polish a knife. Now, you have some clear knowledge about how to polish a knife in the right way.
