Why We Use Salvaged Railroad Spikes to Make Your First Knife

Every railroad spike that ends up on our anvils has already worked a full career. Decades of holding steel rail to wooden ties. Freight trains, freezing Canadian winters, and the kind of constant vibration that would fatigue most metal into cracking. By the time one of these spikes gets pulled from service and lands in our shop, it's already proven itself.

That's exactly why we chose it as the material for your first knife.

A Spike With a Past

Railroad spikes aren't manufactured for looks. They're built to a strict engineering standard, drop-forged to hold thousands of pounds of steel under load, in weather that swings from -30°C to +35°C, for decades at a stretch. Retired spikes get pulled during track maintenance and rail replacement.

We salvage that steel and give it a second job. Instead of getting melted down anonymously in a bin of mixed scrap, it comes to our shop still shaped like what it was, carrying mill marks and surface rust that tell you it's the real thing. Part of what makes this experience land the way it does is that you're not starting with a blank rectangle of bar stock from a supplier catalogue, you're starting with an object that already has a history, and you get to decide what it becomes next.

Why Reusing the Metal Actually Matters

There's an environmental case here that's easy to skip past, so let's not skip it. Making new steel from raw ore means mining, smelting, and rolling, a genuinely energy-intensive process from start to finish. A retired spike has already absorbed all of that cost. Reforging it into a knife means we're not asking the earth for anything new, we're just giving already-existing steel a second, sharper purpose instead of letting it sit in a scrap pile or a landfill.

This isn't scrap steel picked up off the ground. It's steel that already passed a multi-decade stress test. If it had a flaw, it would've cracked or sheared in the track bed long before it ever reached us. What lands on our bench has already been vetted by the harshest quality control there is: real-world use.

And then there's the simple waste math. A retired spike that doesn't get reforged into something new typically ends up in a scrap pile waiting to be melted down and re-rolled into raw stock again, a whole extra industrial cycle before that steel becomes useful to anyone. Reforging it directly into a knife skips that cycle entirely. The energy and material that already went into producing it don't get thrown away and replaced; they get put straight back to work. That's the kind of small-scale, practical reuse we'd rather build a workshop around than just talk about.

Okay, Let's Geek Out on the Steel for a Second

Here's the part most blacksmithing content won't tell you straight: railroad spikes stamped "HC" for "High Carbon" are not high-carbon steel in the way a knifemaker means it. Spikes are governed by specs, and depending on the grade, they typically run somewhere between about 0.15% and 0.4% carbon, with added manganese for extra strength and toughness. True high-carbon blade steel usually starts north of 0.6% carbon, sometimes well above that.

The manganese is added specifically to boost strength and impact resistance without sacrificing ductility, which is exactly what you want in something that has to survive a freight train's worth of vibration without snapping. It's a completely different design goal than a knife steel, which is optimized to hold a fine edge rather than absorb impact. Same base metal, engineered for opposite jobs.

We're telling you all of this on purpose, because it's not a downside, it's the whole reason this steel is such a good place to start.

Why This Steel Is Built for Practice

That's the whole workshop, in practice. Your spike gets brought up to forging heat, then you're the one working it down at the anvil, drawing out the shank, shaping the profile, establishing the bevel by hand under an instructor's eye. Part of what you're actually learning in that moment is how to read steel by colour: the difference between a dull red that's too cool to move easily and a bright orange-yellow that's ready to shape, without ever touching a thermometer. That skill alone is the foundation of blacksmithing, and this steel gives you a wide, patient window to learn without punishing a beginner's inevitable timing mistakes.

Then the knife moves to the 2x72 belt grinder, and this is a completely different skill from anything you just did at the anvil. Grinding is its own art. How much pressure you're putting on the belt, the angle you're holding, how evenly you're moving across the blade, all of it decides whether you end up with a clean, consistent bevel or one that's lopsided and over-thinned in spots. It's easy to underestimate until you're standing at the grinder realizing that a light, steady hand matters just as much as a well-timed hammer swing. The wire wheel finishes the job, cleaning up the surface for a good final look.

It's also just genuinely forgiving to work with at every stage. If your first pass at the bevel isn't quite right -whether that's at the anvil or the grinder- you can bring it back and correct course. The steel doesn't get temperamental about being reheated, reground, or reworked a few extra times while you find your rhythm. That matters more than people think in a two-hour workshop, because it means the material can absorb a student's learning curve instead of punishing it.

We don't heat-treat or quench blades in this workshop, and that's deliberate — hardening is exactly where warping and cracking sneak in, and it's a hard thing to get right on your first afternoon at a forge. Skipping that step means nobody's two-hour build gets undone in the last ten minutes. Every step that remains — hammer control, grinding control, patience — is built to teach a fundamental on steel that won't punish you for being new at this.

Think of it like learning to drive stick on something with a little give in the clutch before you ever get behind a car that demands perfection. You learn faster because the material meets you where you are, instead of fighting you the whole way.

Not a Lesser Knife — a Different One

None of this makes a railroad spike knife a "starter" version of anything. What you walk away with is a real, functional blade forged by your own hands, carrying forge scale and hammer marks that no factory knife will ever have — plus a bit of history, since that steel spent decades holding actual rail line together before it ended up in your grip.

If you eventually want to chase serious edge retention with a true high-carbon steel, that's a different material for a different stage of the journey (We've got a whole separate post on how our two knife workshops actually differ, if you're curious.) The railroad spike knife isn't a rough draft of a "real" knife. It is one.

It's also, frankly, a pretty good place to bring people who've never so much as held a hammer with intent. That's kind of the point of building a workshop around this steel in the first place. It's honest material with a genuine backstory, forgiving enough to let a first-timer walk out having actually made something, rather than watching someone else make it for them.
