This can be checked by hitting the rock with a hammer stone, and checking if the stone chips and breaks away with a sharp edge. Essentially, it must be rated at approximately 7 on the Mohs scale of mineral hardness, or slightly softer than hardened steel. In this video from Wilderness Outfitters, Dave Canterbury discusses the characteristics of a fire-starting flint rock. For more info on these items, check out our fire-starter buyer’s guide from Issue 18 of our magazine. The image above shows several types of flint, chert, agate, and quartz, which can be purchased from Emberlit along with various steel striker pendants. It’s quite simple if you know what to look for. What matters is the stone’s hardness and its ability to form a sharp edge. Common Rocks and Minerals Chert.Commonly known as flint, chert is found in many Kansas limestones as nodules or continuous beds. Streams cut in chert-bearing strata are narrow, boxlike channels, whereas those cut in weaker shales are wider, more gently sloping valleys. However, the name doesn’t matter for the purpose of survival fire-starting. the Flint Hills have cut deep, precipitous channels. It’s important to note that the “flint rock” you find is unlikely to be actual flint or a rock - it’ll probably be some other hard mineral, such as quartz, chert, or agate.
#FLINT ROCK HOW TO#
Unless you’ve made a habit of carrying a dedicated flint rock and steel striker, you’ll need to know how to find flint in the wild.
Using nothing but a piece of high-carbon steel (such as the spine of your knife) and a sharp-edged hard rock, you can generate enough sparks to light a fire. We’ve previously touched on the bow drill and other improvised fire-starters, but one other method to know is the flint and steel technique. Primitive fire-making skills can be a life-saver in difficult circumstances because they enable you to get a campfire going with minimal gear. This can make all the difference in a survival situation.
However, if you were somehow separated from all these tools, would you still be able to start a fire? If the lighter fails to do the trick, you’ve probably got a backup or two in your survival kit - stormproof matches, a ferro rod, or maybe even a camp stove with built-in ignition.
Just whip out a trusty lighter and a few scraps of tinder, and if all goes according to plan, you’ll have a fire going in seconds. Flint Rock Products produces Bridge Deck Aggregate, Non-Skid Aggregate, Grades for Concrete Repair, and Rough Coating Grades. With the aid of modern tools, starting a fire may seem like an easy task.
