A forge skills library and metalworking community — learn to read the heat, swing true, and quench an edge that stays.

01
The craft, in three heats
No secrets. Just temperature, a hammer, and time.
/ 01
Heat the steel
Bring the stock to cherry red and keep it there. Below the critical temp it won't move, above it you burn the carbon out.
/ 02
Hammer the form
Draw it out, upset it, fuller it — every strike either moves metal or consolidates it.
/ 03
Quench the edge
Into the oil, then temper it back. Hard enough to hold, tough enough to flex.
02
Everything but the heat
Learn the craft, not just the image of it.
Forge skills library
Setting up, reading the heat, hammer work, and the quench — the whole craft, step by step.
Read the temperature
The heat-color scale, from black heat to white-hot, and the critical temp every smith knows.
Edged work, done right
Blades, damascus, and heat-treating taught by people who still forge for a living.
Pick your fire
Coal, gas, or induction — what each forge does, and which one suits your shop.
A real community
Makers, bladesmiths, and hammer-ins. Forge alone, learn together.
Field notes
What the old hands know, written down before it's forgotten.

Hot metal, up close
Shot where the sparks actually fly.
04
Read the heat
Every color is a temperature, and every temperature is a decision.
Cherry red at 815°C is the sweet spot — soft enough to move, cool enough to keep the carbon in the edge. White-hot at 1200°C means you've gone too far and the steel is burning.

From the desk of Elias Voss
Most people think forging is about hitting things. It's about knowing when to stop.
I lit my first forge in a rented garage with a borrowed anvil and a hairdryer for a bellows. The first thing I learned: steel will tell you everything, if you watch the color. The second thing: most beginners hit it too much.
A knife is maybe three hundred hammer blows and ten thousand hours of judgment in between. The blows are the easy part. The judgment — when the steel is hot enough, when it's done moving, when to set the hammer down — is the craft.
So that's what we built here. Not a gallery of finished blades, but the judgment in between. The heat colors, the quench line, the reason a two-pound hammer outworks a four-pound one. Everything the old hands know, written down before it's forgotten.

People who finally stopped burning their edges.
★★★★★
"I'd been forging for two years and still couldn't read the heat. The color scale on this site finally made it click."

★★★★★
"The quench guide saved my first real knife. Tempering it right was the difference between a tool and a paperweight."

★★★★★
"I came for the damascus tutorial and stayed for the community. The hammer-ins are where I actually learn."

Questions, answered.
Do I need a real forge to start?+
No. You can start with a firebrick, a hairdryer, and a piece of rebar. The library is written for people at a kitchen table and people in a full shop.
What steel should I buy first?+
1075. It's forgiving, hardens easily, and won't crack if you overshoot the heat once or twice.
Why does tempering matter?+
A fully hardened blade is glass — hard but brittle. Tempering trades a little hardness for toughness so your edge flexes instead of chipping.
Is this only for bladesmiths?+
No. Blacksmithing is hooks, gates, tools, and sculpture too. Blades are just the sharp end of the craft.
How hot is 'cherry red'?+
About 815°C — hot enough that steel moves under the hammer and cool enough to keep the carbon in the edge. The heat-color scale on the homepage walks you through it.
Is it dangerous?+
It's fire and hot steel. Wear natural fibers, eye protection, and closed shoes, and keep a bucket of sand nearby. Respect the heat and it respects you back.
The fire is already lit.
