D2 Steel Guide: The Budget EDC King Explained
Knife steel is the heart of any blade. Composition, heat treatment, and carbide structure determine edge retention, sharpenability, corrosion resistance, and toughness. Understanding steel helps you make informed decisions. This guide breaks down everything.
Our Top Picks for This Category
We evaluated these options based on blade steel performance, ergonomics, build quality, and real-world usability. After extensive testing and comparison, here are the standouts.
- CRKT Pilar — budget. 8Cr13MoV — most common Chinese budget stainless. ~0.8% carbon, 13% chromium with vanadium and molybdenum. Gets sharp quickly, dulls quickly.
- Spyderco SpydieChef — specialty. LC200N (Z-FiNit) — nitrogen-alloyed essentially rust-proof steel. Uses nitrogen instead of carbon for hardness at 58-60 HRC. Impervious to salt water, acids, humidity.
- Spyderco Para 3 LW — mid. CTS-BD1N — Carpenter”s nitrogen-enhanced stainless. Nitrogen improves corrosion resistance and edge retention. Good sharpenability at accessible price.

Edge Retention Explained
Edge retention is determined by carbide content and hardness. Carbides — microscopic hard particles of vanadium, tungsten, niobium, or chromium — resist abrasive wear. High-carbide steels like M390, K390, and S90V dominate edge retention tests. The trade-off: more carbides mean reduced toughness and increased sharpening difficulty.
Heat Treatment Importance
Toughness measures resistance to chipping and fracturing — whether your blade chips hitting a staple or rolls on ceramic. Low-alloy steels like 1095, AEB-L, and 14C28N offer best toughness. High-carbide steels sacrifice toughness for wear resistance — M390 chips more easily than 14C28N despite holding edge much longer. Consider your use case.
Our Recommendation
Steel selection comes down to balancing edge retention, toughness, corrosion resistance, and ease of sharpening for your needs. No “best” steel exists — only best for your use case. Modern powder metallurgy steels like MagnaCut come closest to having it all, but traditional steels remain excellent when properly heat treated.
