How to Make a Spear
Jan 23, · There’s no secret recipe to the process either. To fire harden anything of wood, bone, or antler, simply turn the item over the fire, just above the flames, until it starts to get a little color. Here’s how to use what nature provides to build a spear for hunting and personal defense. Nov 06, · The ready-to-go size will also save you a ton of carving work. Choose live wood or a recently deceased sapling for your spear. Point And Bake It’s literally that easy to make a fire-hardened spear. Carve a point on one end (or both ends), making it as sharp as possible. Rotate the carved area just above the flames of a small fire to dry out the wood.
One of the iconic weapons of the Paleolithic is the fire-hardened spear, its wooden tip carbonized by fire to a wicked point. Unfortunately, it turns out that our hunter ancestors were wrong about fire-hardening. Yes, the charring can make wood slightly harder, but it becomes so much more brittle and weak that there's little overall improvement of the weapon.
After experimenting with their own fire-hardened spears, a group of British biomechanics researchers now believe our ancestors used fire not so much to make a more deadly weapon but to speed up the process of cutting wood into a point. The Clacton Spear is the tip haren a ,year-old fire-hardened spear discovered in England.
The oldest spear ever discovered, the Clacton spear named after the region in England where it was discovereddates backyears. Made by some unidentified ancestors of modern humans, its sharp wooden point was snapped off and buried in soil.
There it was sealed away from the elements and preserved far longer than wood ordinarily can be. When the Clacton spear was discovered in the early twentieth century, archaeologists noticed that its tip had been fire-hardened, using a technique that some hunter gatherer groups how to convert kg to m2 use. It has long been believed that the practice of heating a pointed spear tip in the fire was a way of making it sharper and harder.
But a new paper published in Royal Society Biology Letters suggests otherwise. Two bioscientists at the University of Hull, Roland Ennos and Tak Lok Chan, decided to find out for themselves whether fire really makes spears harder. So they harvested 20 rods from local hazel trees and spent weeks abusing them inside machines of very precise, codified destruction.
First, each rod was divided in half. One half dried naturally over two weeks in the laboratory, and the other half were given a simulated fire-hardening treatment with an experimental rig known technically as a "disposable barbecue.
The rods were removed once they had browned but before they had started to blacken, though two samples had started to char and were discarded. Then they tested each rod for hardness, as well as how each responded to bending and sharp impacts. What they discovered was that the fired wood was what is the best croquet set to buy slightly harder, but it was also significantly weaker.
Compared to the unfired control rods, the fire-treated hazel rods' strength was reduced by 30 percent, and its woodn of fracture," or ability to resist being fractured along its grain after wkoden impact, was reduced by spfar percent. So it would seem that fire-hardening probably did not actually improve spears' effectiveness overall. Any gain in hardness would have been undermined by brittleness. In fact, this very brittleness may be why the Clacton spear tip was broken off in the first place.
The researchers suggest that fire hardening may have begun as a time-saving device. Instead of having to dry and laboriously cut a green rod, an ancient human could slowly toast it in what are polychromos colored pencils fire, scraping off the ashes to make a sharp point at the tip.
In their paper, the researchers conclude that firing cuts labor time dramatically. So maybe our spear-throwing ancestors weren't dipping their weapons in the fire to become even more hardcore. They were just trying to be productive with their time. Royal Society Biology Letters dire, DOI: You must login or create an account to comment.

Aug 09, · I show you how to fire harden a hardwood, as well as explain how it works. Apr 25, · Once you have the tip made, now you will harden it. Place the tip of the spear just above the fire (not way down in it). You will want the flames to just knap the spear point, so we can harden it, but do NOT burn it. The flame causes a chemical reaction that results in a hardened shell over the tip of the spear. How to Fire Harden Wood Step 1. Clean out your fire pit, or create one by digging a wide, shallow hole and lining it with large rocks. Step 2. Add little pieces of charcoal or wood kindling to the fire until you have a steadily-burning flame. It should be Step 3. Hold your wooden object (i.e.
By Tim MacWelch July 31, Fire hardening is a frequently misunderstood concept. Many people think that fire will harden wood by effecting some kind of structural change in the material. Wood is at its softest when it is moist. When wood is dry, it becomes a little lighter in weight and, more importantly, harder—kind of like bread.
To fire harden anything of wood, bone, or antler, simply turn the item over the fire, just above the flames, until it starts to get a little color. Skip the soft woods, like poplar, pine, aspen, and their relatives, which break too easily. One other thing to keep in mind when selecting your materials is its starting dimensions. The ready-to-go size will also save you a ton of carving work. Choose live wood or a recently deceased sapling for your spear. Carve a point on one end or both ends , making it as sharp as possible.
Rotate the carved area just above the flames of a small fire to dry out the wood. It should be golden brown, with little to no black char. You could peel the bark from the shaft, or leave it in place for grip.
Two hanging whitetails in late November served as our test subjects, and an eager group of guys in my survival class served as the test panel. Before I knew what happened, I had inadvertently thrown down the gauntlet of a primitive technology test. Hastily created spears were cut from maple saplings, pointed up with pocket knives, and fire hardened for toughness.
By throwing their spears, the stronger guys were able to penetrate the hide and one side of the ribcage, deep into the vital organs. Wild Game Recipes. Want more hunting and fishing stories? Sign up to receive our emails.
