On the Civivi Brazen Linerlock, listed here in both steels with the same 3.5 inch blade, D2 is for the owner who wants the edge to last through abrasive work. Sandvik 14C28N is for the owner whose edges chip, spot or go too long between sharpenings: D2's own record calls 14C28N a tougher stainless, and 14C28N's maker built it around rust resistance and easy sharpening.
| D2 Tool Steel | Sandvik 14C28N |
|---|---|
| Type | |
| tool steel (semi-stainless / air-hardening) | stainless |
| Made by | |
| Generic AISI grade; produced by many mills. Bohler's proprietary equivalent is K110 (see k110 entry). | Sandvik (Sweden) |
| Composition | |
C 1.4-1.6%Cr 11-13%Mo 0.7-1.0%V ~1.0% (or less, mill-dependent) | C ~0.62%Si ~0.2%Mn ~0.6%Cr ~14.0%N ~0.11% |
| Hardness | |
| 58-62 (up to ~64 with cryo treatment) HRC | 57-59 (typical factory range; the maker's piece-hardening program lists 59, 57 and 55 HRC by tempering temperature) HRC |
| Edge retention | |
| Very good to excellent for its price tier; high carbide volume gives strong wear resistance. | Moderate, trades some wear resistance for toughness and sharpenability. |
| Toughness | |
| Moderate, more brittle than tougher stainless like 14C28N or MagnaCut; can chip on hard use if ground thin. | Very good; well regarded for a fine, consistent grain structure. |
| Corrosion resistance | |
| Only ~12% chromium and most of it tied up in carbides, so D2 is often called 'semi-stainless', it resists light rust better than true carbon steel but will still stain/spot with neglect, unlike 420HC or VG-10. | Very good, engineered specifically for corrosion resistance and easy sharpening. |
| Where it sits | |
| Upper-budget to mid-tier workhorse; long-standing favorite for fixed blades and hard-use folders where cost matters. | Mid-tier value stainless, popular on production folders (e.g., Kershaw, Civivi) as a step up from Chinese Cr-Mo-V steels. |

The Brazen Linerlock listings in D2 and in 14C28N match on nearly everything the distributor text gives, which makes this pair a clean test of the steel. The Civivi Brazen Linerlock is the D2 listing, and the Civivi Brazen Linerlock Black is the 14C28N one. Each has a 3.5 inch blade, a 4.5 inch closed length, a black G10 handle, a pocket clip, a lanyard hole and an extended tang, and the spec rows list each as a linerlock. The two are priced about the same, and the records place both steels around the middle of the market, D2 at upper-budget to mid-tier and 14C28N at mid-tier, so neither side of this pair is a premium step and cost does not decide it.
The wording differs in a few places besides the steel. The D2 blade is described as black stonewash and the 14C28N blade as stonewash. The D2 text also calls its blade a tanto and lists a black nylon zippered storage case; the 14C28N text mentions neither, which is a gap in the wording rather than proof of a difference. With that much shared, the steel line is where your decision sits.
Between D2 and 14C28N, the toughness question is answered by the D2 side. The record behind D2 steel rates its toughness moderate and calls it "more brittle than tougher stainless like 14C28N or MagnaCut". Sandvik 14C28N is rated very good for toughness in its own record. No reading between the lines is needed, because the comparison is written into D2's record.
For the Brazen, that settles one kind of owner. A chip takes metal out of an edge, and a tougher steel is the one less likely to lose it. If your edges come back with small chips in them, the 14C28N Brazen is the tougher answer. The D2 Brazen suits the owner who keeps it on cutting work.
D2 holds its edge longer, and 14C28N gives some of that up by design. D2 carries 1.4 to 1.6 percent carbon, more than twice 14C28N's roughly 0.62, and its record puts edge retention at very good to excellent for a steel of its tier, on the strength of a high carbide volume. 14C28N's record rates edge retention moderate and says the steel gives up some wear resistance to gain toughness and sharpenability. On the Brazen, that means the D2 blade keeps cutting longer through abrasive material, and the 14C28N blade is the one made for easy sharpening.
Rust follows the same split. 14C28N is a stainless with a very good corrosion rating, and its record calls it "engineered specifically for corrosion resistance and easy sharpening"; it also carries about 14 percent chromium to D2's 11 to 13. D2 is semi-stainless, and its record says most of that chromium is tied up in carbides and that neglect will still leave the steel stained or spotted. So the D2 Brazen suits an owner who wipes the blade dry after wet work, and the 14C28N Brazen is more forgiving of one who forgets.
Kershaw sells D2 and Sandvik 14C28N too, but on different models, so its shelf makes a looser comparison. The Kershaw Iridium DuraLock Gray puts D2 on a 3.5 inch stonewash blade with a gray anodized aluminum handle and a DuraLock; the Kershaw Leek puts 14C28N on a 3 inch stonewash blade with a black anodized aluminum handle and a linerlock, and its listing gives the origin as USA where the Iridium's gives China. The steel records, and so the trade, are the same as on the Brazen, but choosing between those two also means choosing a size, a lock and a handle. On the Brazen, D2 against 14C28N comes down to the steel.
The figures on this page are the published specification ranges for the alloy, cross-checked against manufacturer datasheets and independent metallurgical references. They describe the steel, not any one knife. Hardness in particular is a range a mill and a knifemaker work inside, and Knives Now does not test the heat treat of individual knives, so nothing here is a claim about what a specific listing measures.
