8Cr13MoV is a good budget-grade stainless steel, but it is considered low-end or "bad" if compared to premium, high-cost super steels. It is a Chinese-manufactured continuous-cast steel that is highly popular for everyday carry (EDC) folding pocket knives, kitchen cutlery, and budget-friendly workhorse tools.
The Good: Strengths
Highly Affordable: Keeps production costs incredibly low, allowing reputable brands to offer quality knives under a modest price point.
Extremely Easy to Sharpen: It is a relatively soft stainless steel that accepts a razor-sharp edge quickly, making it perfect for beginners learning to use a whetstone.
Good Corrosion Resistance: The 13% to 14.5% chromium content qualifies it as a true stainless steel. It easily resists rust from humidity, rain, and daily wear.
Decent Toughness: It possesses surprisingly high toughness for a conventional high-carbon stainless steel, resisting chipping and rolling under standard cutting tasks.
The Bad: Weaknesses
Mediocre Edge Retention: It dulls significantly faster than mid-range steels like D2 or premium options like S35VN. You will have to sharpen it frequently under heavy use.
Not for Hard Use: It is not meant for heavy prying, batoning wood, or cutting highly abrasive industrial materials.
Quality Depends on Heat Treatment: Because it is inexpensive, poorly manufactured knives will feature subpar heat-treats. However, established brands like Spyderco and Kershaw are famous for extracting maximum performance out of this specific alloy.
How it Compares
AUS-8: 8Cr13MoV is the Chinese equivalent to Japanese AUS-8 steel. They perform almost identically, though AUS-8 sometimes enjoys stricter quality control tolerances.
D2 Tool Steel: D2 holds an edge much longer and is harder. However, 8Cr13MoV is much easier to sharpen and resists rust noticeably better.
If you are looking for a low-cost pocket knife that you do not mind sharpening often, 8Cr13MoV is an excellent value. If you want a knife that stays sharp through weeks of heavy cutting, look for a premium powder metallurgy steel instead.
