Polishing knives on a leather stroop is an important step in keeping your blades in excellent condition. It will keep your kitchen, hunting or workshop tools not only sharp, but also durable. In this article we will discuss how to use a leather strop correctly, the properties of polishes and how to apply strop balm.
A leather strop is a tool that allows you to precisely polish the edge after sharpening. Regular use of the strop ensures that the blade is kept as sharp as possible and the surface is perfectly smooth, resulting in a better quality of cut and longer knife life. A strop made from high quality cowhide, offers two sides - smooth and rough - so the tool can be tailored to the user's preference.
Properties of honing compounds
Polishes are an essential part of the polishing process, not only giving the blade a mirror-like smoothness, but also protecting it from corrosion and discolouration. The polishes available on the market, are characterised by different gradations depending on the degree of abrasiveness:
- Red paste (gradation 2000): Medium abrasive paste, ideal for pre-polishing the blade after sharpening.
- White paste (grit 5000): A fine grit paste that removes micro-scratches and gives the blade its initial lustre.
- Green paste (grit 8000): A very fine-grained paste that gives the blade a high lustre and final smoothing.
- Black paste (12000 grit): Ultra fine grained paste for mirror finish and maximum smoothness.
The choice of paste depends on the condition of the blade and the effect you wish to achieve. It is important to use the pastes as directed, applying a thin layer (approx. 1g) on the side of the blade corresponding to the chosen gradation. Honing compounds contain lanolin and beeswax, which further soften and condition the leather, contributing to a better polishing effect.
How to apply polish correctly?
The correct way to apply a polish to a leather strop is as follows:
- Choose the right paste for the blade.
- Apply a thin layer of paste to one or both sides of the strop.
- Make several movements with the blade in the 'away from you' direction, maintaining the correct angle.
- Repeat the same steps on the other side of the blade.
It is important not to mix different pastes on the same surface as this can affect the effectiveness of the polish. Instead, it is recommended to completely remove one paste before applying another.
Applying balm to the strop
Leather Balm is an optional but useful product. It helps to soften and condition the leather, preventing cracking and prolonging the life of the blanket. It is a good idea to apply the lotion after prolonged use, usually after about 200-300 polished knives. A minimal amount of lotion (approximately 1ml) should be massaged into the leather until completely absorbed.
Maintenance and paste replacement
The polishing paste should be replaced approximately every 300-500 blades sharpened. To replace the paste correctly
- Remove the old paste by scraping it off with a knife, then sand away the residue with 100 grit sandpaper.
- Clean the strop and apply a small amount of lotion to soften the leather.
- Apply a fresh layer of polishing compound.
In conclusion
Using a leather strop in combination with the right polishes and lotions is the way to achieve perfectly sharp, smooth and long-lasting blades. Regular polishing knives will not only improve the quality of your cut, but will also extend the life of your tools. By following these simple steps, your knives will always be ready for use and caring for them will be a pleasure.
