The polishing paste for metalsThe polishing paste for metals in cutlery but in general the abrasive paste is a product widely used during the finishing phase of the custom knife and which serves to create a surface wear (abrasion) of an object by rubbing, in order to modify the external properties of the same.

From this paste also derive polishes with abrasive characteristics (but more diluted), which originally have functions similar to protective wax.

Metal polishing paste and abrasive paste are both tools used in cutlery and metalworking to achieve desired finishes on knives and other metal objects.

Here is some information about both products:

  1. Abrasive paste:
    • Abrasive paste is a compound based on abrasives, such as silicon carbide or aluminum oxide powders, mixed with a binding substance, often oil or water.
    • This paste is used to remove excess material from a metal surface or to prepare the surface before polishing.
    • The abrasive paste has various grain sizes, ranging from very coarse to very fine, depending on the intended use. Coarser pastes will remove more material, while finer ones will be used for more precise finishes.
    • It is useful for removing scratches, stains or marks from the metal surface, or for creating a uniformly matte surface before polishing.
  2. Polishing paste for metals:
    • Polishing paste for metals is similar to abrasive paste but contains finer abrasives, such as chromium oxide or cerium oxide.
    • This paste is used to make a metal surface smoother, shinier and shinier after it has been prepared with abrasive paste or after other processing.
    • It is commonly used to achieve a mirror or glossy finish on knives and other metal objects.
    • It can also be used to remove surface scratches and imperfections, as well as giving greater shine to the surface.

The polishes with abrasive characteristics mentioned in your message seem to be a variation of polishing pastes with a slight abrasive component.

These products could be used to combine the functions of polishing and removing surface defects.

The choice between abrasive paste and polishing paste will depend on the desired final appearance for the custom knife or metal object you are working on, as well as the current condition of the metal surface and the level of finish required.

Polishing techniques

A distinction should be made between two completely different techniques which contribute to improving the reflection of a slightly rough surface:

  • the controlled abrasion of the surface, by means of very fine-grained and uniform abrasives (abrasive paste), which effectively reduces the extent of surface roughness (as in the case of steel and metals in general or oreficeria stones);
  • the use of waxy substances (usually with a high refractive index) that fill micro roughness and give the impression of a less rough surface (as in the case of waxes).

The important distinction between two different polishing techniques:

  1. Controlled abrasion with abrasive paste:
    • This technique involves the use of very fine-grained and uniform-grained abrasives, such as abrasive paste, to remove materials from the surface of the object in order to reduce surface roughness.
    • The abrasive paste is applied and rubbed on the metal or other material surface to remove imperfections, scratches and small roughness. As the abrasive paste is used, a smoother and more even surface is obtained.
    • This process is widely used to improve the reflection of metal and precious stone surfaces in jewelry and goldsmithing.
  2. Use of waxy substances or wax to fill micro asperities:
    • This technique involves applying waxy substances or waxes to the surface of the object to fill micro bumps or small imperfections on the surface.
    • The waxes used often have a high refractive index, which means that they are able to increase the reflection of light on the treated surface, giving the impression of a less rough and more shiny surface.
    • This method is commonly used for finishing and protecting wooden objects, furniture, wood floors, and in some leather processing applications.

Both techniques have their specific purpose and can be used in combination to achieve optimal results depending on the material and the type of reflection desired on the surface.

The choice between these two techniques will depend on the specific needs of the project and the desired final appearance.

Using polishing paste for metals in the cutlery

This product is used in different fields and can also take different names, from the dermatological field with hand-washing paste, from the mechanical field (metal objects) and aesthetic with chrome-cleaners, to jewelry with polishing abrasive pastes, to bodywork.

It is mainly used to remove small surface imperfections that have not affected the entire thickness of any surface treatment, and is also used for polishing.

The polishing paste for metals is a versatile product that is widely used in various sectors, including cutlery.

Here’s how it’s used in cutlery and other contexts:

  1. Cutlery:
    • In cutlery, metal polishing paste is often used to improve the aesthetic appearance of custom knives or knives in general.
    • After the processing and sanding phase of the knife, the metal surface may have small imperfections, scratches or marks.
    • The polishing paste is applied to the metal surface and rubbed with a cloth or pad to remove these small imperfections and to obtain a brighter and more uniform finish.
    • It is especially useful for obtaining a sharp and shiny blade on kitchen or collectible knives.
  2. Mechanical field:
    • Metal polishing paste is also used to improve the appearance and finish of metal objects in general, such as machine parts, tools and mechanical components.
    • In this context, it is used to remove surface imperfections, scratches and marks, as well as to give a glossy or satin finish to metal objects.
  3. Aesthetics (chrome-care):
    • In chrome-specific cleaning products, known as “chrome-care,” polishing paste is often an essential component. These products are used to clean and protect chrome surfaces on cars, motorcycles and other objects.
    • The polishing paste is applied to remove dirt, oxidation and small stains from the chrome surface, then to polish the surface to make it shinier and more resistant.
  4. Jewelry shop:
    • In jewelry, polishing abrasive pastes are available specifically for use on precious metals such as gold and silver.
    • These pastes are used to remove scratches and surface imperfections from jewelry, then to polish and restore the precious metals to their original shine.

In general, polishing paste for metals is a very useful product to improve the aesthetic appearance of metal surfaces and to remove small surface imperfections without affecting the entire thickness of the material.

Its application will depend on the specific application and needs of the project.

Composition of polishing paste for metals

This paste uses a powder that, depending on its use, has a grain more or less thin and constant and that makes up for the most part, uses a soap that allows smoothness and optimal use, in addition depending on the applications can be composed even with a thinner.

The exact composition of polishing paste for metals may vary depending on the manufacturer and the specific needs of use, but in general, polishing paste for metals contains the following main components:

  1. Abrasive: This is the main component of polishing paste and determines the degree of abrasion and polishing. The abrasive can consist of fine powders of materials such as aluminum oxide, cerium oxide, chromium oxide, diatomite (a siliceous mineral), or silicon carbide. The choice of abrasive will depend on the specific application and desired finish.
  2. Soap or binder: Soap or binder is used to bind the abrasive into a cohesive and uniform paste. This component also gives the necessary smoothness when applying and removing the paste. The type of soap or binder used may vary, but is often based on fats or oils.
  3. Thinner (optional): Depending on the application, the metal polishing paste may contain a thinner to adjust the consistency of the paste. The diluent can be a solvent such as water or an organic solvent, depending on the specific needs of the product.
  4. Other additives (optional): Depending on the specific needs of the product, other additives such as anti-oxidant agents to prevent metal oxidation, coloring agents to give the paste a specific appearance or additives to improve lubrication and smoothness properties may be added.

The grain of the abrasive and its uniformity may vary depending on the application.

For example, for very fine finishing processes, thinner and more uniform abrasives will be used, while coarser abrasives will be used to remove scratches or more obvious imperfections.

The choice of specific ingredients will depend on the objective of polishing and the characteristics of the metal or material treated.

Against directions

Such a product given its abrasive characteristics should not be used for parts that have a subtle surface treatment,as it can cause its removal or thinning by changing its characteristics.

Polishing paste for metals, given its abrasive nature, can cause the removal or thinning of thin surface treatments on metal parts.

Therefore, it is important to consider some contraindications and precautions when using this paste:

  1. Parts with thin coatings: Metal parts with thin coatings, such as plating, varnishing, anodizing or delicate surface treatments, can be damaged by the polishing paste. The abrasive can remove or damage these coatings, altering the characteristics and appearance of the surface. It is essential to avoid the use of polishing paste on these parts or apply it with extreme caution.
  2. Delicate materials: The polishing paste can be too aggressive for delicate materials or softer metal alloys. In these cases, it is necessary to carefully consider whether the use of the paste can compromise the integrity of the material or cause unwanted damage.
  3. Objects with tight tolerances: If you’re working on parts with tight dimensional tolerances or parts that require dimensional accuracy, keep in mind that dough abrasion may affect the size and accuracy of parts. You can consider using protection or masking methods to prevent the paste from reaching critical areas.
  4. Very dirty or corroded pieces: Before using the polishing paste, it is important to thoroughly clean the metal parts. If the paste is applied to very dirty or corrosive surfaces, it could channel contaminants or worsen corrosion, causing further damage.

To avoid unwanted damage, it is essential to know well the material you are treating and its specific characteristics.

In case of uncertainty, it is advisable to carry out a test on a small hidden area to assess the impact of the paste before applying it on a larger surface.

In addition, always consult the instructions of the polishing paste manufacturer for specific guidance on the safe and appropriate use of the product.
