Short answer: Damascus for looks and edge feel, D2 for hard use, 440C for wet environments, VG10 for a fine kitchen edge that needs almost no maintenance. All four are good steels. The wrong one for your use is what makes a knife disappointing.
The four in plain terms
1095 and 15N20 Damascus
High carbon, not stainless. Hardened to 58 to 60 HRC. Takes a very fine edge, sharpens easily on a plain stone, and shows the layered pattern that people buy Damascus for. It will spot or rust if left wet, which is the trade you accept. Best for hunting, collecting, display and anything that gets wiped down after use.
D2 tool steel
Semi-stainless with high chromium and carbide content, usually run around 58 to 60 HRC. Holds an edge noticeably longer than most carbon steels and shrugs off abrasive work. Harder to sharpen when it finally goes, and it takes a slightly toothier edge rather than a polished one. Best for heavy field use, skinning several animals in a season, and knives that live in a truck.
440C stainless
A genuinely stainless steel with enough carbon to harden properly. Corrosion resistance is its whole point. Edge retention is good rather than exceptional, and it sharpens easily. Best for fishing, coastal use, kitchen knives that go in a sink, and anyone who knows they will not oil a blade.
VG10 stainless
A Japanese stainless with vanadium and cobalt. Takes a very fine, very keen edge, holds it well for a stainless, and resists rust. Slightly more brittle than 440C if you pry with it. Best for chef and paring knives, and for folders where a clean slicing edge matters more than brute strength.
Side by side
Rough guidance rather than laboratory numbers, based on how these steels behave on our benches.
- Edge retention: D2, then VG10, then Damascus, then 440C.
- Ease of sharpening: Damascus, then 440C, then VG10, then D2.
- Rust resistance: 440C and VG10, then D2, then Damascus.
- Toughness against chipping: Damascus and 440C, then D2, then VG10.
- Looks: Damascus, and it is not close.
Pick by what you actually do
- Deer or elk once or twice a year, wiped and oiled after: Damascus.
- Several animals a season, or a knife that gets worked hard: D2.
- Boat, dock, saltwater, filleting: 440C.
- Home kitchen, every day, hand washed: VG10 or 440C.
- Display, gift or collection: Damascus.
- Balisong you will flip for hours: D2 or Damascus, both are fine; handle material matters more here.
Questions people ask
Is Damascus stronger than a single steel?
No. Historically layering evened out inconsistent steel. Modern mono-steels are consistent to begin with, so today Damascus is chosen for the pattern and the feel, not for strength.
Is stainless steel weaker?
Not weaker, different. The chromium that stops rust also forms carbides that can make the steel slightly less tough at very high hardness. In normal use you will never notice.
What hardness should I look for?
For a working knife, 58 to 60 HRC is the sweet spot. Softer than 56 and it goes blunt quickly; harder than 62 and it starts chipping instead of rolling.
Which do you make most of?
Damascus, by a long way, followed by D2 and 440C. Browse them in hand-forged Damascus, D2 tool steel and 440C stainless.
