Full Review of 440C As For Blades


As a knife enthusiast, there’s something endearing about the reliable hardness of 440C stainless steel. With a typical Rockwell hardness ranging from 58-60 HRC, it’s hard enough to keep its edge through various cutting tasks, but not so hard that it becomes brittle. This balancing act is an art in and of itself, a testament to the prowess of metallurgical engineering. The hardness of 440C makes it a reliable companion in the kitchen, the great outdoors, or simply in day-to-day cutting chores.


Toughness is where 440C shows its subtle charm. It’s not the toughest steel out there—that accolade belongs to the likes of CPM-3V or INFI—but for a stainless steel with high hardness, 440C still puts up a good fight against chipping and cracking. It won’t take kindly to being used as a prying tool or an axe, but for ordinary cutting tasks, it can take the punches and roll with them. This unassuming resilience is what makes 440C a mainstay in many a knife aficionado’s collection.

Ease of Sharpening

In a world where increasingly complex super steels demand diamond sharpeners and hours of patience, the ease of sharpening 440C is refreshingly uncomplicated. A standard whetstone or ceramic rod can bring back its edge in minutes. As someone who takes a zen-like pleasure in the sharpening process, I’ve come to appreciate this straightforwardness. The tactile feedback, the rhythmic movements, the gleaming edge at the end—it’s a process that 440C makes enjoyably simple.

Edge Retention

While the edge retention of 440C may not compete with ultra-high-end steels like ZDP-189 or M390, I’ve found it more than adequate for everyday tasks. From slicing apples to opening packages, a 440C blade stays sharp long enough to be reliable, without the fussiness associated with super hard steels that are difficult to sharpen. Plus, there’s a unique satisfaction in honing a knife that’s seen some use—a ritual that 440C participates in willingly.

Corrosion Resistance

Living in a coastal town, I’ve seen what saltwater can do to many types of steel. Here, 440C’s good corrosion resistance comes into play. Its high chromium content (16-18%) makes it capable of withstanding moisture well, and with a little maintenance—a rinse and a wipe after use—it holds up admirably. It’s no marine steel like H1 or LC200N, but for a general-use knife steel, it does a commendable job.


Perhaps the most appealing aspect of 440C is its cost. The steel offers a level of performance that, while not cutting-edge, is more than satisfactory for the price. I’ve often recommended 440C knives to beginners or those on a budget. There’s a joy in discovering that good performance doesn’t always have to come with a steep price tag, and 440C exemplifies that brilliantly.
