VG10 vs HAP40: The Steel Wars – Why Your Knife’s Heart Matters
Most people buy a knife based on looks. A pretty handle. A cool finish.
Big mistake.
A knife isn’t a fashion accessory. It’s a tool. And like any tool, it lives and dies by what it’s made of.
The steel is everything.
I’ve been in kitchens since I was a kid — interned at Noma at 13, and later opened restaurants in Hong Kong and Bali. I’ve worked with $10 knives and $1,000 customs. The real difference? It’s not the handle. Not the grind.
It’s the steel.
Let’s talk about VG10 and HAP40 — I use both, but for very different reasons.
VG10: The Workhorse
VG10 is what I reach for when I’m in the zone and need to move fast.
It’s cobalt-alloyed stainless steel, usually around 60–61 HRC.
Here’s what that means in the kitchen:
-
It holds an edge well — but not too hard to sharpen
-
It resists chipping and corrosion
-
It’s easy to maintain
I use VG10 when I’m chopping onions, breaking down fish, trimming pork.
It’s dependable.
Like a good sous chef — reliable, sharp, and always ready.
HAP40: The Racehorse
Now, HAP40 is a different animal.
It’s a powdered metallurgy, high-speed tool steel — 64–68 HRC.
What does that mean?
-
Extremely hard
-
Incredible edge retention
-
Demands serious sharpening skills
I once prepped over 100 duck breasts with a HAP40 blade and didn’t need to strop once.
That’s the magic: it stays sharp forever… until it doesn’t.
And when it finally dulls? You’ll need diamond stones, time, and patience.
This is not a steel for cleaving bones or smashing garlic.
This is for precise cuts — for chefs who want their knife to feel like an extension of their hand.
