The alloy typically contains chromium, which helps prevent rust, ensuring that the knife maintains its edge and appearance over time, even in humid or wet conditions.
- High Carbon Steel: High carbon steel blades are prized for their excellent edge retention and sharpness, although they require more maintenance to prevent rusting. This type of steel can be honed to a very fine edge, providing superior cutting performance, but users need to be diligent about cleaning and oiling the blade regularly.

- Damascus Steel: Known for its distinctive patterns and aesthetic appeal, Damascus steel combines different types of steel to create a strong and flexible blade. While it delivers good durability and edge retention, its unique craftsmanship often comes at a higher price point, making it less common in budget auto knives.
- Ceramic: Ceramic blades are incredibly sharp and lightweight, providing a unique alternative to traditional steel blades. However, they are more brittle and can chip or break under heavy stress, making them less suitable for tasks requiring heavy-duty use, but ideal for precise cutting tasks.
