Knife steel

1095 knife steel

A classic simple high-carbon steel known for taking a very keen edge and reaching high hardness, but shallow-hardening and less forgiving to heat treat consistently than steels like 1084.

Also known as

AISI 1095

How 1095 behaves

The four meters are relative to the rest of the database. Composition is the published nominal analysis, not a mill certificate for your bar.

Working properties

Toughness: 2 / 5
Edge retention: 2 / 5
Corrosion resistance: 1 / 5
Ease of grinding: 5 / 5

Composition: Carbon (C)0.90–1.03%
Manganese (Mn)0.30–0.50%
Best uses: Popular for traditional and budget fixed blades, kitchen knives, and differentially heat-treated blades (including forge-hardened and clay-tempered styles) where a very keen, hard edge is the priority.

What each property means for this steel

Open the property you are worried about. Every note is written for the blade in your hand, not for a spec sheet.

Toughness

Middle-of-the-road toughness for a simple carbon steel, and generally less tough than higher-manganese steels like 1084 at a comparable hardness. Its high carbon content trades some toughness for hardness potential and edge sharpness.

Edge retention

Good for a simple carbon steel thanks to its high carbon content and the hardness it can reach (58-62+ HRC), taking a very keen edge, though it lacks the wear-resistant carbides of alloy tool steels.

Corrosion resistance

No chromium and no corrosion resistance to speak of. Requires regular oiling and drying like any plain carbon steel.

Grinding and machinability

Very easy to grind, like other simple carbon steels with no hard alloy carbides to fight through.

More on 1095

1095 is one of the most recognizable simple high-carbon steels in knifemaking, prized for taking an extremely keen edge and reaching high hardness. Its low manganese content makes it shallow-hardening, which means it needs a genuinely fast quench to reach full hardness, and it has a reputation for being less forgiving in a home shop than steels like 1084 that have more manganese to boost hardenability.

1095 FAQ

Is 1095 stainless?

No, it is a plain carbon steel with no chromium and needs regular oiling and drying to prevent rust.

Is 1095 hard to heat treat?

Yes, more so than 1084. Its low manganese content means it needs a fast quench, often brine or a fast oil, to reach full hardness, with a higher risk of warping or cracking than more forgiving steels.

Gloved hand lowers a glowing orange knife blank point-first into an open steel oil tank with light vapor and a lid beside it.

Is 1095 hard to sharpen or grind?

No, it is easy to work with standard belts and stones. The difficulty with 1095 is in heat treating, not grinding. See the full grinding and sharpening guide.

Two hands hold a chef's knife flat on a damp bench stone in a wooden holder, fingertips pressing the blade face.

How does 1095 compare to 1084 or 52100?

1084 is more forgiving to heat treat thanks to its higher manganese content, while 52100 offers meaningfully better toughness and edge retention. See the full breakdowns: 1084 vs 1095 and 52100 vs 1095.
