Everything else in this house is priced. This is not. Bring steel you already own — bought, inherited, or found in a dead man's attic — and the house will read it, write its upkeep, size you for it, and keep the record. And if you would rather forge your own than buy ours, Forge Wisdom teaches the whole craft: the fire, the steels, the heat treatment, and the recipes. No coin. No purchase, now or ever.
Warborn sells steel. Here the house gives away how steel is made. Everything below is old, published, testable craft — no secret is kept back because it might cost us a sale. If you would rather build your own forge and forge your own sword than buy ours, this hall is for you, and you owe the house nothing for it.
Numbers are given as ranges because steel is not a recipe card — believe your supplier's datasheet over ours where they differ. Held to house law WB-GOV-024: what the house cannot defend, it refuses to say, and every refusal is printed at the foot of this page.
Forge Wisdom is the first of the March's three schools, beside the War Table and Sea Faring, reckoned together at The Convergence. Standing and access only — never Marks, never coin, never a discount. Convergent multi-curriculum competence gating — US application 19/791,538, patent pending.
Carbon, quench, heat, temper — and the truth the catalogs leave out.
Wall-hangers, blunt trainers, axe bodies, thick single-hand blades.
Too little carbon to hold a keen edge for long, but very hard to break. Most cheap 'battle-ready' swords are 1045 and that is not always an insult.
The honest middle: cutting swords, machetes, working axes.
The best strength-to-forgiveness ratio for a first sword. It will take a real edge and still survive your mistakes.
Knives, seax, arming swords, hard-use choppers.
Near-eutectoid: it hardens evenly and deeply and is very tolerant of an imperfect heat. This is the beginner's steel that professionals never stop using.
Knives, hamon work, differentially hardened blades.
Takes a screaming edge and cracks if you look at it wrong. Shallow-hardening, which is exactly why it makes a beautiful hamon — and exactly why long blades in 1095 warp.
Long swords, greatswords, anything that must flex and come back.
Leaf-spring steel. The single most forgiving alloy for a sword-length blade — it bends where 1095 would shatter. If you are making your first sword over 30 inches, make it from this.
Spring-tempered performance swords.
Silicon buys enormous elastic range: a 9260 blade can take a 90° bend and stand back up. Harder to grind, and it does not hold an edge like 1080.
The bright layer in pattern-welded steel; premium tough blades.
The nickel resists etchant, which is why 15N20 shows silver against dark 1084 in damascus. L6 bainite is the toughest sword steel known — and the most difficult heat treat in the craft.
Historical cores, guards, pommels, mail rings, fittings.
Cannot be hardened, will not hold an edge, and is nearly impossible to break. Historic swords were often an iron core with a steel edge welded on — not because smiths were poor, but because it worked.
Knives. Not swords.
The house says this plainly: do not forge a sword-length stainless blade. The chromium carbides make long blades brittle and the heat treat needs a controlled atmosphere kiln. Stainless swords are decorative. Full stop.
Three forges, from twenty dollars to four hundred. All of them work.
Why you would: Reaches forge-welding heat, costs almost nothing, and teaches you fire management as no gas forge can.
Why you would not: Smoke, clinker, and a fire that must be tended constantly. Not for an attached garage or a suburban yard on a still day.
Why you would: Lights in thirty seconds, holds an even temperature, and lets you concentrate on the steel instead of the fire.
Why you would not: Rarely welds without flux and patience; propane costs add up; and carbon monoxide means ventilation is not optional.
Why you would: This is how every sword before 1700 was made. It costs nothing and it will teach you more about fire than any book.
Why you would not: Devours fuel, throws sparks, and has no walls to hold heat. It is a teacher, not a shop.
What is truly needed, what can be cheated, and what only money buys.
Five things. Everything else is convenience.
Mass under the hammer is what moves steel. Rebound matters more than horn or shape.
The cheat: A cut-off length of railroad track stood ON END (not laid flat) gives you a better working face than a laid track and costs a case of beer at a scrapyard. A forklift tine is better still.
Heavier is not faster. A 2.5 lb hammer swung correctly for an hour beats a 4 lb hammer swung for ten minutes.
The cheat: Dress the face convex and polish it — hammer marks are just a rough hammer face printed into your blade.
A blade dropped from loose tongs at 2000 °F is how people lose feet. Fit the tongs to the stock, not the other way.
The cheat: Your very first project should be a pair of tongs. It teaches drawing, bending, punching and riveting at once.
Ninety percent of a finished blade is grinding, not forging. The 2x72 belt grinder is the single biggest upgrade in the craft.
The cheat: Start with files and a 4.5" angle grinder. Slow, honest, and it teaches your eye the geometry.
Heat treatment, not forging, decides whether your sword is a weapon or a crowbar.
The cheat: A cheap kitchen thermometer in the toaster oven — never trust the dial. They lie by 75 °F routinely.
Buy these in this order, as money allows.
Fullers and shoulders by hand are misery; by hardy tool they are three heats.
Pin holes, guard slots, and pommel threading want a square hole, not a hopeful one.
You cannot straighten what you cannot see. Every blade warps in the quench.
Non-magnetic (the Curie point, ~1414 °F) is your free, dead-accurate temperature gauge.
The difference between one blade a week and one blade a day. Not needed. Wanted, deeply.
Fire, forging, heat treatment, two full recipes, damascus, and safety.
Judging heat by colour is impossible in daylight — a blade that looks orange in a sunlit doorway is 300 °F hotter than one that looks orange in a dim shop. Every smith who ruins steel in the summer learns this the same way. Shade your forge, or work at dusk.
Faint red ~1100 °F, too cold to move. Dark cherry ~1400 °F, the low edge of forging. Bright cherry to orange 1500–1700 °F, where you should be doing almost all your work. Yellow 1900 °F, forge only heavy sections here. White with sparks — that is your steel burning. Sparks coming off the work are carbon leaving it, and it does not come back.
Note: Craft-lore, calibrated to a dim shop. A pyrometer beats any eye.
Too much air burns the surface of your steel away as scale and strips carbon from the skin — the exact carbon you need at the edge. Keep the fire fuel-rich, the work buried in the heart of the coals, never sitting in open flame above them. In a gas forge this means dialling the burner slightly rich until you see a soft feather of flame at the door.
Never hammer below dark cherry. Cold-working carbon steel opens micro-cracks along the edge that will not appear until the quench, when the blade splits and you blame the oil. When it goes dull red, back in the fire. Most beginners lose a blade to impatience in the last thirty seconds of a heat.
Nine parts: the edge, the forms, the fittings, the harness, proof, buying, history, and the road to making and dealing yourself.
Symptom, cause, cure — the faults every smith meets in the first year.
Why: Too fast a quench medium for the alloy, cold oil, an un-radiused shoulder or sharp corner, an uneven heat, or hammering below dark cherry earlier in the day.
The cure: Warm the oil to 120–130 °F, match the medium to the alloy, radius every corner, and never cold-work carbon steel. A cracked blade cannot be saved; break it and read the grain to learn from it.
Why: Uneven heating, entering the quench at an angle, swirling sideways, or uneven bevel thickness pulling one side harder.
The cure: Quench edge-first, straight down, no sideways motion. Straighten while still above about 400 °F, or clamp between blocks during the temper cycles and let the temper set it straight.
Why: It did not harden. Too cold, too slow a quench, or too long between the fire and the oil.
The cure: Re-normalise, then re-harden hotter and faster — check with a magnet, and reduce the walk from forge to quench tank to under two seconds.
Why: Over-hard, under-tempered, or ground too thin behind the edge for the work.
The cure: Temper 25–50 °F higher for two more hours, and thicken the edge angle by two or three degrees.
Why: Under-hard or over-tempered — the opposite failure.
The cure: Re-harden and temper lower. A rolled edge can be steeled straight in the field but it will roll again.
Why: You are not reaching the apex — you are grinding the shoulder of the bevel, not the edge.
The cure: Raise a burr along the full length before changing grits. Colour the edge with a marker and look at where the abrasive actually removes it.
Why: You moved up a grit before the previous one had removed all of the one below it.
The cure: Change the direction of grinding with each grit, ninety degrees apart, and do not advance until every scratch runs one way.
Why: Not hot enough, oxide in the joint, too little flux, or the first blow was too heavy.
The cure: Clean both faces bright, flux at a low red, bring to bright yellow with a reducing fire, and set the weld with light fast taps before you draw it out.
Why: You are burning it. Carbon is leaving and it does not come back.
The cure: Cut the burnt section off entirely. Turn the air down, bury the work deeper in the coals, and watch the colour.
Why: The peen has loosened, the grip core has compressed, or wood has dried and shrunk.
The cure: Re-peen carefully, or shim under the guard. Stop using it for cutting until it is solid.
Why: Pitting holds moisture, or the storage environment swings in humidity.
The cure: Polish the pits out or accept them, then store with a vapour-corrosion inhibitor and a stable temperature. Re-oil monthly.
Why: The eye was never fully seated, the wedge is too short, or the haft has dried out.
The cure: Re-hang it properly — never soak a haft to swell it, which rots the wood and loosens worse. Seat the head fully on the shoulder and use a full-length wooden wedge.
