Making a wooden spear is straightforward: find a straight sapling or branch, strip the bark, shape one end to a point, and harden the tip over a fire. The whole process can take as little as an hour with a knife, or a full afternoon if you want a polished, durable result. Here’s how to do it well.
Choosing the Right Wood
Your wood choice matters more than any other step. You want a straight-grained hardwood that resists snapping under pressure. Ash, oak, hickory, and maple are all excellent choices. If you’re working in a coniferous area, spruce and pine work too. The oldest known wooden spears, found at an archaeological site in Germany and dating back roughly 300,000 years, were carved almost entirely from spruce and pine trunks.
Look for a piece that’s as straight as possible, about 1 to 1.5 inches in diameter, and free of large knots or cracks. A sapling trunk works better than a branch because saplings grow straighter and have more consistent grain running the full length. Avoid brittle woods like willow or soft woods like poplar, which split too easily under force.
For length, a good starting point is roughly four-thirds your height. If you’re 5’9″, that puts you around 7.5 feet, though many people prefer something shorter for easier handling. A practical range is 5 to 7 feet. You can always trim it down, so err on the longer side when cutting your blank.
Green Wood vs. Dried Wood
Fresh-cut (green) wood is significantly easier to carve because the moisture makes the fibers soft and pliable. If you’re making a spear in the field with just a knife, green wood is the practical choice. The downside is that green wood tends to warp or split as it dries over the following days and weeks. The fibers also have more elasticity, which means small cuts can close back up as you carve, making fine detail work harder.
Seasoned (dried) wood is more stable and holds its shape permanently, but it’s much harder to carve by hand. If you have access to tools like a drawknife, spokeshave, or rasp, seasoned wood will give you a better long-term result. Air-drying a fresh sapling takes weeks to months depending on thickness and climate. If you’re making a spear for a project rather than an emergency, cutting your wood and letting it dry for two to four weeks in a sheltered spot with good airflow will reduce warping later.
Stripping and Shaping the Shaft
Start by removing all the bark. You can do this with a knife by scraping the blade perpendicular to the shaft, pulling toward you in long strokes. On green wood, bark often peels away in strips if you score a line down the length first. Remove any branch stubs by cutting them flush with the shaft, then shave them smooth.
Once the bark is off, check for any bends. Minor curves in green wood can sometimes be straightened by heating the bent section over a fire (not in the flames, but close enough to feel uncomfortably hot to your hand) and then holding it straight as it cools. This works best on green wood where the moisture turns to steam and allows the fibers to resettle.
Smooth the entire shaft by scraping it with your knife blade held at a 90-degree angle to the wood, or by sanding with a rough stone. This removes splinters and gives you a comfortable grip. The archaeological spears from Schöningen were finished exactly this way: the makers scraped and abraded the entire surface smooth after shaping.
Carving the Tip
The tip is where most people rush and make mistakes. You want a gradual taper, not a pencil point. A good spear tip tapers over the last 6 to 10 inches of the shaft, ending in a point that’s sharp but not so thin it snaps on contact.
Carve by removing thin slices from the tip toward the shaft, rotating the spear a quarter turn after every few strokes to keep the taper symmetrical. This splitting technique, working from the point backward, is the same method used on the oldest known spears. It follows the grain naturally and reduces the chance of accidentally removing too much wood from one side.
Keep the pith (the very center of the wood) running along the side of the point rather than exiting directly at the tip. This makes the point more durable because the hardest outer wood surrounds the softer core. If the pith runs straight out the tip, the point is more likely to split on impact.
Fire Hardening the Tip
Fire hardening is the process of slowly drying and heat-treating the tip to make it harder and more resistant to blunting. It works by driving moisture out of the wood fibers and partially breaking down the softer cellular structures, leaving behind denser material.
Build a bed of hot coals rather than working over open flames. Hold the carved tip a few inches above the coals and rotate it constantly, the way you’d roast a marshmallow if you actually wanted it evenly golden. The wood should darken to a tan or light brown. If it starts turning black or smoking heavily, pull it away immediately. You’re aiming for slow, even heating, not charring.
The key temperature window is between 100°C and 200°C (roughly 210°F to 390°F). In this range, the wood dehydrates and the internal chemistry shifts as moisture and volatile compounds cook off, leaving the surface harder. Go above that range and you start creating char, which is brittle and flakes away. According to USDA Forest Products Laboratory research, temperatures above about 150°F (65°C) applied for extended periods permanently change wood’s properties. The goal with fire hardening is to stay in the zone where you’re driving out water and toughening fibers without weakening the deeper structure.
The whole process takes 10 to 20 minutes of patient rotation. When the tip looks evenly tanned and feels noticeably harder when you press a fingernail into it, it’s done. Let it cool completely before handling.
Finishing and Protecting the Wood
An untreated wooden spear exposed to weather will eventually crack, dry out unevenly, or start to rot. If you plan to keep it long-term, a simple oil finish goes a long way.
Linseed oil (also called flaxseed oil) is one of the most traditional options. It penetrates deep into the wood grain and protects against humidity changes that cause cracking. Rub a thin coat over the entire shaft with a cloth, let it soak in for 15 to 20 minutes, then wipe off the excess. Repeat two or three times over the course of a day or two. Raw linseed oil dries slowly, sometimes taking days to fully cure. Boiled linseed oil (which contains chemical driers, despite the name) cures faster but is not food-safe if that matters for your use.
Tung oil is another solid choice. It dries harder than linseed oil, offers better water resistance, and doesn’t yellow over time. It’s been used as a wood finish in East Asia for thousands of years. Apply it the same way: thin coats, wiped on and buffed off.
If you’re in the field without access to commercial oils, animal fat rubbed into the wood provides short-term moisture protection. It won’t cure and harden like plant-based drying oils, but it buys you time.
Adding a Stone or Metal Point
A sharpened wooden tip works, but adding a separate point made from stone, bone, or metal dramatically improves penetration. To attach a point, split the tip of the shaft about 2 to 3 inches down using a knife or by carefully tapping a thin wedge into the end grain. Seat the base of your point into the split, then bind it tightly with cordage. Wrap in a crisscross pattern above and below the point’s base, pulling each wrap tight. Sinew, rawhide, or strong natural fiber cord all work. If you have access to pine resin or hide glue, coating the binding adds waterproofing and extra hold.
An alternative to splitting is to carve a shallow notch or shelf at the tip and lash the point directly against it. This keeps the shaft intact but requires more cordage and a flatter point base to sit securely.
