When it comes to choosing the right pocket knife, one of the most crucial factors to consider is the type of steel used for the blade. The steel determines the knife’s performance, durability, and ease of maintenance, making it a critical aspect in selecting the perfect pocket knife for your needs. This comprehensive guide will delve into the various factors to consider when choosing a steel, including hardness, toughness, corrosion resistance, edge retention, ease of sharpening, price, and availability. We will also discuss some of the most popular pocket knife steels in the market, helping you make an informed decision for your next purchase.

What to consider when picking a pocket knife steel
When choosing a steel for a pocket knife, it is essential to consider several factors to ensure the knife meets your requirements and performs well in various conditions. Here are some important factors to consider:
- Hardness: Hardness is a measure of a steel’s resistance to deformation and is usually measured using the Rockwell C scale (HRC). A higher HRC value indicates better edge retention and wear resistance, but it may also make the steel more brittle and difficult to sharpen.
- Toughness: Toughness refers to a steel’s ability to withstand impacts and resist chipping or breaking. A balance between hardness and toughness is crucial for a pocket knife, as you want it to be strong enough for various tasks but not so hard that it becomes prone to breaking.
- Corrosion resistance: Some steels are more resistant to rust and corrosion than others. Stainless steels, such as 440C, VG-10, or S30V, offer better corrosion resistance, which is especially important if you plan to use your pocket knife in wet or humid environments.
- Edge retention: Edge retention refers to how well a steel maintains its sharpness during use. Steels with better edge retention, like S30V or M390, will stay sharp longer, reducing the frequency of sharpening.
- Ease of sharpening: Some steels are more comfortable to sharpen than others. A pocket knife with a steel that is easy to sharpen, like 1095 or AUS-8, is advantageous if you need to maintain the edge frequently or if you’re a beginner at sharpening.
- Price: The price of the steel can impact the overall cost of the pocket knife. Premium steels, such as M390, CPM-20CV, or S110V, often come at a higher price, while more affordable steels, like 8Cr13MoV or 440C, offer good performance for their price.
- Availability: Some steels are more readily available than others. When choosing a steel, ensure that it is accessible and that there is enough supply for the knife you want.
- Intended use: Consider the primary tasks you plan to use your pocket knife for, as this will help you determine the best combination of properties in a steel. For example, if you will mostly use your knife for cutting food, you might prioritize corrosion resistance and ease of sharpening over toughness.
Popular steels for use in pocket knives
- 420HC: A budget-friendly stainless steel, known for its ease of sharpening and decent corrosion resistance. It has lower edge retention compared to other steels, but it’s an excellent choice for casual users.
- 440C: A widely used stainless steel offering a good balance between hardness, toughness, and corrosion resistance. It has better edge retention than 420HC and is relatively easy to sharpen.
- AUS-8: A Japanese stainless steel known for its balance of edge retention, ease of sharpening, and corrosion resistance. It’s a mid-range steel and a popular choice for affordable knives.
- VG-10: Another Japanese stainless steel, VG-10 has better edge retention and corrosion resistance than AUS-8. It’s a popular choice for Japanese folding knives and kitchen cutlery.
- 8Cr13MoV: A Chinese stainless steel similar in performance to AUS-8. It offers a good balance of toughness, edge retention, and corrosion resistance, often found in affordable pocket knives.
- 1095: A high carbon steel with excellent toughness and ease of sharpening. It has lower corrosion resistance, making it more suitable for knives that will not be exposed to moisture regularly. It’s popular for fixed blade knives and traditional pocket knives.
- D2: A semi-stainless tool steel known for its excellent edge retention and hardness. D2 is more challenging to sharpen than some other steels and has moderate corrosion resistance.
- CPM S30V: A premium stainless steel developed by Crucible Industries, known for its excellent edge retention, corrosion resistance, and toughness. It is more challenging to sharpen but is a popular choice for high-end folding knives.
- CPM S35VN: An evolution of CPM S30V, S35VN offers better toughness and ease of sharpening while maintaining excellent edge retention and corrosion resistance. It’s widely used in premium pocket knives.
- M390: A premium stainless steel produced by Bohler-Uddeholm, known for its exceptional edge retention, corrosion resistance, and toughness. It’s more challenging to sharpen but is highly sought after in high-end knives.
- CPM 20CV: A premium stainless steel, similar to M390 in performance, with excellent edge retention, corrosion resistance, and toughness. It’s often used in high-end folding knives.
- CPM 154: A powder metallurgy version of 154CM, offering improved toughness, edge retention, and corrosion resistance. It’s a popular choice for custom folding knives.
Conclusion
In summary, the type of steel used in a pocket knife significantly impacts its performance and overall suitability for your needs. By understanding the different characteristics of various steels, such as hardness, toughness, corrosion resistance, edge retention, and ease of sharpening, you can make a more informed decision when selecting your next pocket knife. Remember to consider your budget, intended use, and personal preferences when weighing the pros and cons of each steel option. With this comprehensive guide as your starting point, you can confidently choose a pocket knife that will serve you well for years to come.
