China's VG-10 equivalent: a legitimately competitive steel, inconsistently executed.
10Cr15CoMoV
For the Newcomer
10Cr15CoMoV is a Chinese stainless steel with a composition essentially identical to VG-10: same carbon, same chromium, same A metal alloying element. In knife steel its real job is tempering resistance for high-temperature coatings, not edge or toughness gains., similar molybdenum and vanadium. The name is a direct Chinese chemical description: 10 = ~1% C, Cr15 = 15% Cr, Co = cobalt, Mo = molybdenum, V = vanadium. In composition and potential performance, it is a legitimate VG-10 equivalent. The real issue is inconsistency. Quality makers like Xinzuo and HEZHEN apply rigorous heat treatment and match VG-10's performance, while less scrupulous operations attach the designation to poorly treated blades. The steel is not the problem; execution is.
About this composition
The execution gap. Two knives with identical 10Cr15CoMoV steel designations can perform very differently. Xinzuo claims precision heat treatment to 60 ± 1 Rockwell C, the standard hardness scale for blade steel. Most kitchen knives fall between about 56 and 66. with vacuum furnace and cryo; untracked OEM operations may heat treat inconsistently to 58 HRC or below. ChefPanko's real-world test: well-treated Chinese 10Cr15CoMoV matches VG-10 in blind cutting tests, while poorly-treated samples developed rust that genuine VG-10 did not after equivalent use.
Performance Deep Dive
Edge retention: Very good when properly heat treated, matching VG-10 in controlled tests.
A standardized industry test that measures how much material a blade can slice before going dull; the standard edge-retention benchmark.-equivalent estimates run to ~800–1,000 cuts for both 10Cr15CoMoV and VG-10 in comparable testing. Cobalt provides the same tempering resistance benefit as in VG-10. Poorly heat-treated examples perform significantly below this.
Toughness: Moderate, same as VG-10.
At 59–62 HRC with cobalt, it shows similar toughness characteristics to VG-10. LeeKnives Charpy: 25–30 J/cm².
Corrosion resistance: Good when heat treatment is correct.
At 15% Cr with proper Mo content, genuine 10Cr15CoMoV performs well in kitchen environments. ChefPanko's pro kitchen test found that properly-treated VG-10 showed zero rust after 3+ years, while Chinese 10Cr15CoMoV did develop some rust. That suggests heat treatment and finishing quality meaningfully affect real-world corrosion resistance even at identical composition.
Ease of sharpening: Easy to moderate, similar to VG-10.
Cobalt's tempering resistance effect produces similar sharpening characteristics.
⚠ The fake-Japanese-knife caveat: brands like Huusk, Sakuto, Seido, Matsato, and similar dropship operations do NOT use 10Cr15CoMoV. They typically use 3Cr13 or similar budget steel and sometimes reference premium steel names without using them. Legitimate 10Cr15CoMoV brands are transparent about Chinese origin: Xinzuo, HEZHEN, CIVIVI, SENCUT.
Research Notes
This steel's primary distribution channel is Amazon and direct brand websites. It is not carried by the major artisan knife retailers (JKI, CKTG, Knifewear, Tosho). Xinzuo and HEZHEN are the only confirmed brands with published HRC specs and documented quality heat treatment. Treat any other 10Cr15CoMoV claims from unknown brands with significant skepticism.
In the Kitchen
If you want VG-10-class performance at $60–$80 and you're willing to buy from Xinzuo or HEZHEN specifically, this steel delivers. The catch is verification: the same designation on a Huusk or Sakuto knife is almost certainly a lie about the actual steel inside. Buy the maker, not the marketing label.

Composition
| Element | % | Role |
|---|---|---|
| Carbon (C) | 1 | High; hardness and carbide formation, same as VG-10 (range 0.95–1.05) |
| Chromium (Cr) | 14.75 | Stainless protection; matches VG-10 range (14.0–15.5) |
| Cobalt (Co) | 1.25 | Tempering resistance; same function as in VG-10 (range 1.0–1.5) |
| Molybdenum (Mo) | 1 | Hardenability, corrosion; same as VG-10 (range 0.80–1.20) |
| Vanadium (V) | 0.22 | Minor wear resistance; slightly lower than VG-10 (range 0.15–0.30) |
| Manganese (Mn) | 0.4 | Structural |
Steel family: Conventional ingot stainless. Chinese GB national standard designation. zknives.com lists it as equivalent to Takefu VG-10, Ahonest Changjiang VG-10 Cobalt, and Nachi Fujikoshi MVS10Cob. The composition is near-identical to VG-10; differences are within batch-to-batch variation of a single steel grade.
