Not All Steel is Created Equal
And
🥷 Not All High-Carbon Steels Are Created Equally
(Some Just Cut Deeper)
If VG‑10 is the stainless golden retriever of knife steels—loyal, reliable, and low maintenance—then Aogami #2 is the sleek, slightly feral samurai sword of your kitchen drawer.
Also known as Blue Paper Steel #2, this Japanese high-carbon legend doesn’t come to play. It comes to slice like a myth, patina like poetry, and rust if you so much as blink the wrong way. And yes, we still love it.
Why? Because Aogami #2 is for the purists. The ones who:
- Respect the blade.
- Understand the edge.
- Accept the occasional rust spot as the price of greatness.
If VG‑10 is your weekday hero, Aogami #2 is your Sunday soul blade—the one you pull out when it’s time to carve brisket like a Shogun or slice sashimi with reverence.
It’s not for everyone. But if you’re the kind of dad who tunes your own grill burners and sharpens your own blades, you might’ve just found your spirit steel.
Let’s break down what makes Aogami #2 one of the sharpest, most temperamental, and most legendary steels ever forged.
🔍 What Is Aogami #2 Steel (and What Makes It Special?)
Aogami #2, or Blue Paper Steel #2, is the blade steel equivalent of that quiet old guy at the end of the bar who used to be a black belt, a fighter pilot, and probably wrestled a bear once.
It doesn’t brag. It doesn’t sparkle. But when it moves—it moves with precision, power, and purpose.
🏯 The Ancestry of Aogami
Made in Japan by Hitachi Metals, Aogami #2 is an evolution of another legend: Shirogami (White Paper Steel).
Take Shirogami, toss in a little tungsten and chromium, and boom—Aogami #2 is born.
“Aogami” literally means blue paper — named for the color of the wrapping used by Hitachi, not because the steel turns blue (though it does patina beautifully if you’re into that kind of thing).
🧪 Composition Breakdown (Grumpified)
Here’s the no-fluff version of what’s in Aogami #2:
- ~1.1–1.2% Carbon (C): Super sharp, super hard, super unforgiving.
- ~0.3% Chromium (Cr): A little rust resistance. Not enough to save you.
- ~1.0–1.5% Tungsten (W): Improves edge retention. Makes the steel tougher than it has any right to be.
- ~0.2% Vanadium (V): Refines grain for even sharper edges.
This blend gives Aogami #2 a Rockwell Hardness around 62–64 HRC — a serious number for serious blades.
⚙️ Why It Matters:
- Sharpness: Aogami #2 gets scary sharp. We’re talking “slice the air thin” sharp.
- Edge Retention: It stays sharp longer than your in-laws’ unsolicited advice.
- Refinability: Want a screaming sharp edge with just a few swipes on a whetstone? This is your steel.
- Patina Party: As a high-carbon steel, Aogami #2 develops a natural patina over time. That’s not damage—it’s character.
Think of Aogami #2 as a cast-iron skillet: it needs attention, but rewards you every time.
🧠 TL;DR (Too Long; Didn't Read.):

🥋 Why Aogami #2 Has a Cult Following and Is Worth the Work
You don’t just own an Aogami #2 knife. You commit to it.
That’s why the people who use it—chefs, butchers, collectors, and backyard grill samurais—don’t just like it. They swear by it. Some even swear at it (usually while oiling out a rust spot), but they still come back.
Here’s why Aogami #2 inspires lifelong loyalty—and just a little bit of steel-wielding madness.
🔪 1. That Edge Is Criminally Sharp
There’s sharp, and then there’s “did I just cut that onion by looking at it?” sharp.
Aogami #2 gets and holds a razor-thin edge with surgical precision. We’re talking:
- Sashimi without tearing
- Tomatoes that cry when they see you coming
- Brisket slices so clean you could frame them
It’s the kind of edge that makes you rethink every other knife in your kitchen—and your life choices.
🔄 2. It Sharpens Like a Dream
Sharpening Aogami #2 on a whetstone is like tuning up a vintage muscle car: it’s part science, part therapy.
- Fast feedback: You’ll feel and hear the difference as you sharpen
- Scary efficient: A few passes and you’re back in the game
- Grain structure: Fine-grained, so it takes a mean edge and likes it
If you’re the kind of dad who takes pride in doing things right, this is your steel.
🎨 3. It Patinas Like a Work of Art
Yes, Aogami #2 rusts if you ignore it. But before it rusts, it patinas.
That darkened layer? It’s a protective film and a badge of honor. A story written in steel.
- Cut a lemon? It turns bluish.
- Slice meat? It deepens.
- Use it for years? It looks like something that should be under museum glass.
Every patina is unique. Like a fingerprint. Or a dad joke you’ve told too many times.
🧘♂️ 4. It Makes You Slow Down (In a Good Way)
Aogami #2 doesn’t rush. It doesn’t tolerate laziness. It wants to be:
- Cleaned.
- Dried.
- Stored with care.
And in exchange? It becomes an extension of your hand. A tool with soul.
Owning Aogami #2 turns cooking from a chore into a practice.
Into something you get better at, not just something you do.
🤝 5. It Connects You to Centuries of Craftsmanship
This steel isn’t new. It’s part of a legacy that dates back to Japanese swordsmiths. It’s made in small batches, by people who take metallurgical purity as seriously as you take brisket bark.
When you use an Aogami #2 blade, you’re joining a tradition of:
- Simplicity.
- Precision.
- Respect for materials.
It’s a throwback to when tools weren’t disposable—and neither was your attention span.
🧠 TL;DR
Reason | Why It Matters |
Extreme sharpness | You’ll never look at your other knives the same |
Easy to sharpen | Actually rewarding to maintain |
Patina potential | Turns into a steel diary |
Demands care | Makes you a better cook, by default |
Samurai roots | Not just a tool, a legacy |
Composition Breakdown – What’s Actually Inside Aogami #2?
If Aogami #2 were a whiskey, it’d be barrel-aged, high-proof, and hand-labeled by a guy named Kenji who’s been doing it for 40 years. This steel isn’t mass-produced junk—it’s intentionally crafted, precisely blended, and fiercely sharp.
Let’s break down what’s under the hood (without putting you to sleep):
🧪 Aogami #2 Steel Composition (aka “What Makes the Magic”
Element | % Range | What It Does (No Nerd Speak) |
Carbon (C) | ~1.1–1.2% | Gives the blade its extreme sharpness. Also why it’ll rust if you leave it wet. |
Tungsten (W) | ~1.0–1.5% | Boosts hardness and helps the steel stay sharp under pressure. |
Chromium (Cr) | ~0.3% | A little rust resistance, but not enough to slack off on maintenance. |
Vanadium (V) | ~0.2% | Refines the grain structure. Translation: cleaner, smoother edges. |
Manganese (Mn) | ~0.2–0.3% | Adds strength and helps with the forging process. Like a spotter at the gym. |
Silicon (Si) | ~0.1–0.2% | Slight boost to wear resistance. Not flashy, but important. |
Aogami #2 is based on Shirogami #2 (White Steel #2), but with added tungsten and chromium to toughen it up a bit and give it better edge life.
🧠 What This Means in Real Life:
- Sharp AF: That 1.2% carbon content? It’ll slice meat, vegetables, and your sense of superiority if you’re not careful.
- Tool steel performance: It acts like the high-performance gear you wish your cordless drill was.
- Forging flexibility: Blacksmiths love it because it takes a wicked edge and survives a temper tantrum in the forge.
- Hard, but not brittle: Thanks to the tungsten and vanadium, it stays durable without chipping like a diva.
🔬 Compared to Other Steels:
Steel | Hardness | Rust Resistance | Sharpenability | Grumpy Dad Rating |
VG‑10 | 60–61 HRC | ✅✅✅ (High) | ✅✅✅ | 🔪🔪🔪🔪 (Practical pick) |
Aogami #2 | 62–64 HRC | ❌ (Low) | ✅✅✅✅✅ | 🔪🔪🔪🔪🔪 (Sharpening joyride) |
D2 Tool Steel | ~60 HRC | ✅✅ (Moderate) | ✅✅ | 🔪🔪🔪 (Tough but tricky) |
🔧 In English, Please?
- Aogami #2 is a razor that remembers its edge.
- It’s not a diva, but it needs drying and a little attention.
- It sharpens fast, wears long, and never phones it in.
This is steel that’s proud to be steel. No fancy laminates. No gimmicks. Just raw, carbon-powered slicing power.

Using Aogami #2 – What It’s Great At (and What It’s Not)
Aogami #2 isn’t a Swiss Army knife. It’s not here to open beer bottles or cut through frozen burritos.
This steel is built for precision, performance, and ritual.
Here’s the brutally honest guide to when it shines—and when it sulks.
✅ What Aogami #2 Is Fantastic At:
🔪 Slicing Meat (Raw or Cooked)
Think brisket, pork belly, or that steak you reverse-seared like a backyard boss.
- Clean cuts = better flavor retention
- No tearing = no juice loss
- Edge = samurai-tier
“Cuts meat like it owes you money.”
🐟 Sashimi, Sushi, and Delicate Proteins
Fish fear it. Chefs revere it.
- Zero drag, zero mash
- Precision slicing without wrecking texture
- Responds to micro-angle changes like a surgeon’s scalpel
Ideal for dads who learned sushi from YouTube but want to look pro.
🥦 Vegetables That Deserve Respect
No, it’s not just for meat. Aogami #2 makes quick work of:
- Tomatoes
- Onions
- Cabbage
- Mushrooms
- Zucchini (yes, even zucchini)
Clean cuts mean less cell damage = better taste. (Science, baby.)
🧱 High-Volume Prep
A properly forged Aogami #2 knife will go the distance.
- It’ll hold its edge for longer sessions
- You’ll spend more time slicing, less time sharpening
- It’s built for service-level use (but makes weeknight chili feel fancier)
❌ What Aogami #2 Should Avoid (Trust Us on This)
🚫 Cutting Through Bone or Frozen Food
Not built for brute force. Try this and you’ll chip the edge—and your pride.
Use a cleaver. Or a saw. Or just rethink your life choices.
🚫 Sitting Wet in the Sink
- No. Just… no.
- This steel will rust fast
Overnight in water = orange regret
“I’ll clean it later” is how legends die
Wash. Dry. Oil. Repeat. It takes 20 seconds and saves you years of therapy.
🚫 Careless Users
This isn’t a good “first knife” unless you’re also ready for “first tetanus shot.”
- Kids, roommates, or that one guy who cuts limes on the countertop? Nope.
- If your knife lives in a drawer with scissors and loose batteries? Also nope.
🧠 TL;DR: Situational Report
Task | Aogami #2 Performance |
Meat slicing | 🔪🔪🔪🔪🔪 |
Sushi prep | 🔪🔪🔪🔪🔪 |
Veggie prep | 🔪🔪🔪🔪 |
Frozen food / bones | 💀💀💀 |
Dishwasher life | 😱 |
High-volume sessions | 🔥🔥🔥🔥🔥 |
Show-off moments | 🎯💯🔥 |

Care and Maintenance – Keep It Alive (or Regret Everything)
Aogami #2 knives aren’t fragile—but they do demand respect. Like an old-school shop teacher or a well-seasoned cast iron skillet, they’ll reward you if you put in the time. Otherwise? They’ll rust, chip, and judge you from the drawer.
Here’s how to keep your Blue #2 blade looking sharp and slicing cleaner than your mother-in-law’s side-eye.
🔄 Honing vs. Sharpening: Know the Difference
Honing = realignment
Sharpening = metal removal
You hone to maintain the edge. You sharpen to bring it back from the dead.
Tips from actual grumpy knife owners
Task | Frequency | Tools | Dad Tip |
Honing | Every few uses | Ceramic rod or leather strop | Quick, satisfying, keeps edge on point |
Sharpening | Every 1–2 months (with use) | Whetstone (1000/6000 grit) | Go slow. Feel the steel. Respect the angle. |
Honing is your marriage maintenance. Sharpening is therapy after it’s too late.
🛢️ What Oil to Use (And What to Avoid)
You don’t need a high-tech lab oil. But your blade does need a light coating to prevent rust, especially after heavy use or anytime it’ll sit for a while.
Recommended:
- Camellia Oil: Traditional, food-safe, and doesn’t go rancid. Samurai-approved.
- Mineral Oil: Cheap, odorless, available everywhere.
- Knife-Specific Oils: Like Tsubaki or Ballistol. Fancy, but effective.
Avoid:
- Cooking oils (olive, canola, etc.): They turn your knife into a sticky rancid mess.
- WD-40: It’s a knife, not a squeaky door hinge.
- No oil at all: Unless you like orange freckles on your blade.
🎨 Patina Pride: Why Rust Can Be Sexy
Not all oxidation is bad. In fact, Aogami #2 develops a natural patina over time—a dark, moody layer that looks like a steel autobiography.
Patina = good.
Rust = bad.
Patina | Rust |
Dark blue, grey, black | Orange, flaky, red |
Forms gradually | Forms overnight if wet |
Protective | Destructive |
Tells your knife’s story | Tells the story of neglect |
Your blade’s patina is like beard stubble: if it’s intentional, it’s cool. If it’s just laziness, not so much.
