Let's talk about the Cast 440C used by the Serrata
It is thus odd to see people refer to 440C as some kind of low end/sub steel and S30V as some kind of high end steel when the differences are on the order of ~10%. Just imagine talking about differences in general in that way. Have you tried D2, that has an extremely coarse carbide structure inherently.

Difficulty sharpening 440C | Kitchen Knife Forums
0. Dec 14, 2014. #1. In the last year I've become proficient with double bevel sharpening thanks to this forum and Jon's videos. I have consistently had more trouble sharpening one knife which is 440C, its a Gunter Wilhelm 8" chef. In particular, detecting a burr is difficult or impossible so I feel like I'm guessing.

440c Steel Vs D2 | Which Steel Should You Pick? | Skilled Cutter
440c is a stainless steel as it has 16-18% chromium, whereas d2 has only 12% chromium. So, obviously, d2 can't even compete with the corrosion resistance of 440c. So, D2 is having rust very early and needs more maintenance. 4. Edge retention. When it comes to greater edge retention, D2 is a choice over 440c.
Stainless Steel – Grade 440C (UNS S44004)

440c any good | BladeForums.com
6,478. Jan 16, 2002. #10. IMO, 440C is one of the best knife steels out there. It isn't the "latest greatest" fad steel; and some feel that unless it's 154CM, CPM440V, etc., it's a poor steel, but that does not change the fact that 440C is excellent all-around.

4116 Steel vs 440C
The primary difference between 4116 steel and 440C steel is their amount of chromium. 4116 steel contains between 13 and 15% chromium, while 440C steel contains between 16 and 18% chromium. This difference in chromium content gives 440C steel better corrosion resistance than 4116 steel. Additionally, 440C steel has a higher hardness and …
Schrade (USA) "High-Carbon Stainless Steel" == 440C?
But, that is different from the "high-carbon stainless" listing for the 127UH. In reading the FAQ, archives and search results, it is clear to me that many collectors assert that they own Schrades made from 440C. I've heard others insist or imply that Schrade did not use 440C at any time, only 440A and 420HC.

440A Vs 440C Steel | Is There Any Difference? | Skilled Cutter
The answer to this question depends on the application. The main difference between 440A and 440C stainless steel is that 440A has a lower carbon content than 440C. This makes 440A more corrosion resistant, but it is also less hardenable. As a result, 440A is typically used in applications where corrosion resistance is more important than ...
How do you sharpen 440C | BladeForums.com
So, like you've found, a fine edge doesn't seem to last nearly as long as it should (for 440C). As for sharpening it, treat it like a SAK. My mantra for those is 'Less is More'; this means gentler abrasives, finer grit, lighter pressure, and fewer strokes all seem to work much better for steels like these. David. M.
5Cr15MoV vs 440C Knife Steel Comparison
5Cr15MoV is a Chinese stainless steel that's often used in budget-friendly knives. It's comparable to 440A in terms of performance, with moderate edge retention and high corrosion resistance. 440C, on the other hand, is a higher-end American steel known for better hardness and edge retention.

Crucible has been a part of the knife steel industry for many decades, such as with steels like 154CM which was developed in the late 1950's and gained popularity in knives through Bob Loveless in the early 1970s. I wrote about the history of …
N690 vs 440C Steel (Which one is better?)
N690 is a type of high-carbon stainless steel, just like 440C. However, N690 is even better at resisting corrosion compared to 440C. It's also tougher because its microstructure contains chromium carbide instead of iron carbide, which gives it improved resistance against wear compared to 440C. Both N690 and 440C come in various …
7Cr17MoV Steel: Properties, Composition, And Uses
440C blade steel offers better edge retention when compared to 7Cr17MoV as it contains a higher amount of carbon elements in its alloy composition, enabling the formation of a lot more carbides than 7Cr17MoV steel. Both AISI 440C and 7Cr17Mov offer similar level toughness, and most knives with these two types of steel will perform in an …
