Railroad Spike Uses – Transforming Salvaged Steel Into Workshop
Railroad spike uses range from forging high-quality knives and bottle openers to creating industrial-style home decor like coat hooks and door handles. Because they are made of durable, medium-to-high carbon steel, they are also excellent for heavy-duty outdoor applications such as indestructible garden stakes or anchors.
For the best results in the forge, look for spikes marked with “HC” on the head, indicating higher carbon content suitable for heat-treating and edge retention.
Finding a bucket of old, rusted spikes at a flea market or a yard sale feels like uncovering a chest of buried treasure. You see the potential in that rugged, weathered steel, but you might not know exactly where to start your first project.
When you start exploring railroad spike uses, you quickly realize these heavy-duty fasteners are more than just scrap metal. They represent a perfect marriage of history and utility, offering a unique medium for blacksmiths, woodworkers, and DIY enthusiasts alike.
In this guide, we will walk through the most practical and creative ways to repurpose these spikes. Whether you want to fire up the forge or just need some industrial-grade hardware for your mudroom, you are in the right place to get inspired and get working.
Essential Railroad Spike Uses for Blacksmithing and Forging
For many hobbyist blacksmiths, the railroad spike is the ultimate starter material. It is thick enough to practice heavy moving of metal, yet small enough to heat up quickly in a standard propane or coal forge.
Hand-Forged Knives and Blades
The most iconic project for any smith is the spike knife. While most spikes are not “high-grade” tool steel, those marked with “HC” (High Carbon) on the head have enough carbon to be hardened and tempered. These make excellent utility knives, letter openers, or decorative oyster shuckers.
To make a knife, you will typically draw out the shank into a flat blade while leaving the distinctive head intact as a pommel. This creates a “brute de forge” look that is highly sought after in the custom knife community. Always remember to normalize the steel before your final heat treat to reduce internal stress.
Custom Bottle Openers
If you are looking for a quicker project that still tests your skills, a bottle opener is a fantastic choice. You can twist the shank for a decorative grip and punch a hole near the head to create the prying mechanism. The weight of the spike gives the opener a satisfying, substantial feel in the hand.
These openers are incredibly popular as gifts or items to sell at local craft fairs. Because the metal is so thick, you can experiment with different textures using a ball-peen hammer or a cross-peen hammer to give each piece a unique character.
Heavy-Duty Center Punches and Chisels
In the workshop, you often need a tool that can take a beating. You can forge the tip of a spike into a point or a flat edge to create custom shop tools. While they won’t hold an edge as long as O1 or W1 tool steel, they are more than adequate for marking wood or soft metals.
To ensure the tool lasts, you must perform a proper quench. For “HC” spikes, a warm oil quench followed by a light temper in a toaster oven will give you a tool that is hard enough to work but not so brittle that it shatters under a hammer blow.
Practical Railroad Spike Uses in Home Decor and Furniture
You don’t need a forge to find great railroad spike uses around your home. With a drill, a grinder, and a bit of creativity, these spikes can become functional hardware that adds a rustic, industrial vibe to any room.
Industrial-Style Coat and Hat Racks
One of the simplest DIY projects involves mounting spikes to a piece of reclaimed barn wood. By drilling a hole slightly smaller than the spike’s diameter, you can drive the spike into the wood for a friction fit, or use a set screw from the back for extra security.
The flared head of the spike is perfect for catching the loops of heavy winter coats or the brims of hats. For a cleaner look, use a wire wheel to remove the rust and apply a clear coat of lacquer or a wipe-on polyurethane to prevent future corrosion.
Heavy-Duty Door Handles and Pulls
If you are building a sliding barn door or a large gate, standard hardware often looks too flimsy. A railroad spike can be bent or welded into a U-shape handle that feels indestructible. It provides a grip that matches the scale of heavy timber projects.
For those who don’t weld, you can use a heavy-duty epoxy or bolt the spikes directly through the door using a threaded rod. This application highlights the raw aesthetic of the steel and serves as a great conversation piece for guests entering your home.
Unique Bookends and Paperweights
Sometimes, the best use for a spike is to let its weight do the work. By welding three or four spikes together in a geometric pattern, you can create heavy bookends that won’t budge. If you prefer a minimalist look, a single spike polished to a mirror finish makes a striking paperweight for an office desk.
To get that high-shine finish, start with 80-grit sandpaper on a flap disc and work your way up to 600-grit before hitting it with a buffing compound. The contrast between the rugged shape and the refined finish is visually stunning.
Outdoor and Landscaping Applications for Salvaged Spikes
Railroad spikes were designed to live outdoors, so it makes sense to use them in your garden or yard. Their corrosion resistance (especially if they have developed a thick patina) makes them ideal for long-term ground contact.
Indestructible Garden and Tent Stakes
Have you ever had a plastic or thin aluminum tent stake bend on a rock? That won’t happen with a railroad spike. They are heavy, but for permanent tie-downs or securing large tarps in a workshop yard, they are unbeatable. You can even weld a small D-ring to the side for easier rope attachment.
In the garden, these spikes can be used to anchor timber edging or landscape fabric in high-wind areas. Simply drive them through the timber and into the soil. The rust that forms actually helps “grip” the wood and soil over time, making them very difficult to dislodge.
Artistic Garden Markers and Borders
For a decorative touch, you can weld flat washers to the heads of the spikes and use metal stamps to label your plants. These markers will last decades longer than wooden or plastic alternatives. They develop a beautiful orange-brown patina that blends naturally with mulch and stone.
If you have a large collection of spikes, you can drive them into the ground side-by-side to create a low-profile border for a gravel path. It creates a “toothed” look that is perfect for xeriscaping or industrial-themed landscapes.
Technical Tips for Working with Railroad Spike Steel
Before you dive into these railroad spike uses, you need to understand the material. Not all spikes are created equal, and knowing how to handle them will save you time and broken tools.
Identifying High-Carbon vs. Low-Carbon Spikes
As mentioned earlier, look for the “HC” stamp on the head. If there is no stamp, or if it says “MC,” it likely has lower carbon content. Low-carbon spikes are great for decorative items like hooks or handles because they are easier to bend and weld.
However, if you want to make a cutting tool, you need the “HC” variety. Even then, “high carbon” in railroad terms is usually around 0.6% carbon, which is lower than professional knife steels like 1095. It will get hard, but it won’t be “file hard” without a very aggressive quench.
Cleaning and Prepping the Steel
Most salvaged spikes are covered in decades of grease, rust, and road grime. Before you put them in a forge or weld them, you must clean them. A soak in distilled white vinegar for 24 hours will loosen most of the rust, making it easy to scrub off with a wire brush.
If you are welding, ensure you grind back the surface to bright metal at the join point. Old spikes can have “cold shuts” or cracks from their time on the tracks. Inspect the shank carefully for any deep fissures that could compromise the strength of your finished project.
Bending and Shaping Without a Forge
You don’t need a 2000-degree forge to bend a spike. A standard oxy-acetylene torch or even a high-output MAPP gas torch can get a specific spot hot enough to bend in a heavy-duty bench vise. Always use long-handled pliers or tongs, as the heat will travel up the spike quickly.
For cold bending, you will need a massive vise and a cheater pipe for leverage. Be careful, as cold-bending can sometimes cause the steel to snap if there are internal flaws. Heating the metal to a dull red glow makes the process much safer and easier on your equipment.
Safety Precautions for Repurposing Salvaged Metal
Working with old steel comes with specific risks. At The Jim BoSlice Workshop, we prioritize safety so you can keep tinkering for years to come. Follow these rules to stay safe while exploring different railroad spike uses.
- Watch for Galvanization: Some modern spikes are galvanized (zinc-coated). Heating these in a forge or welding them releases toxic zinc fumes that can cause “metal fume fever.” If the spike looks dull grey and doesn’t rust, avoid heating it unless you strip the coating with acid first.
- Eye Protection is Non-Negotiable: When grinding or hammering, hot scale and metal shards fly everywhere. Wear Z87+ rated safety glasses and a face shield when using a bench grinder or angle grinder.
- Legal Salvaging: Never take spikes directly from active railroad tracks. This is trespassing and theft, and it can be extremely dangerous. Buy your spikes from scrap yards, antique stores, or reputable online blacksmithing suppliers.
- Proper Ventilation: Whether you are welding, forging, or using heavy solvents to clean the steel, ensure your shop has active airflow. A simple box fan in the window can make a world of difference for your lung health.
Frequently Asked Questions About Railroad Spike Uses
Can you actually make a functional sword out of a railroad spike?
Technically, no. A railroad spike does not have enough mass or the right metallurgical properties to make a full-sized sword. However, you can forge a “spike dagger” or a small short-sword style blade by drawing the metal out very thin, though it will lack the flexibility required for a true sword.
Are railroad spikes legal to own?
Yes, it is perfectly legal to own railroad spikes. The legal issue arises from where you get them. Taking them from railroad property is illegal. It is always best to purchase them from a legitimate reseller or find them on private property with the owner’s permission.
How do you keep railroad spike projects from rusting?
For indoor items, a coat of paste wax or clear lacquer works well. For outdoor items, you can either let them develop a natural protective patina or use a rust-converter spray followed by an outdoor-rated enamel paint. Many blacksmiths prefer the “oil finish” achieved by wiping the hot metal with linseed oil.
What are the best railroad spike uses for beginners?
The best starter project is a simple S-hook or a wall hook. It requires basic bending and minimal tapering. It teaches you how the metal moves under the hammer without the pressure of creating a sharp edge or a complex weld.
Final Thoughts on Repurposing Railroad Steel
Exploring the various railroad spike uses is a rite of passage for many DIYers and metalworkers. These spikes offer a link to our industrial past while providing a tough, versatile material for our modern projects. From the artistic flair of a hand-forged knife to the rugged utility of a garden stake, the possibilities are only limited by your imagination.
Remember to always check for that “HC” stamp if you’re making tools, and never compromise on safety gear when grinding or forging. There is an immense satisfaction in taking a piece of “junk” and turning it into a tool or a piece of art that will last another hundred years.
So, clear off your workbench, fire up the torch, and start creating. Whether you’re building a rustic coat rack for your entryway or a custom blade for your next camping trip, that old spike is waiting to be transformed. Happy making!
