so I need to get me some rubies, sapphire and diamonds for my 'flint and steel'...LoL in all honesty I find quartz inferior to flint/chert as it doesn't develop the same sharp edges like flint does. Never tried jasper or tiger eye, I have petrified wood but it doesn't have spark edges like my flints do.

Railway lines use a lot of crushed rock as a bed for their tracks most of the time the rock is limestone because it readily available in bulk for cheap and where you have limestone you will always find flint/chert. So walk along a rail track and check out the rocks you will fine stones with flint in them.

Hey Larry! When it comes down to metals there are two particularly important qualities to take into account for bushcraft; Hardness. And toughness. Hardness is a measure of how brittle the metal is - literally. That's all it tells you. It tells you that a metal will chip or snap rather than bend. This is important, because if a metal is not hard, it is soft. And that means when you strike it with flint it will peel, easily, and not use any of the kinetic energy you have provided to get very hot. When a metal is hard, you will 'chip' tiny pieces off of the steel with pressure and friction, which will make the metal very hot in the process. Toughness relates to something entirely different. Two metals might have a hardness of 30 - but one can hold a tonne of weight, and the other will break if you put five pounds on it. Just as an extreme example. The one that holds the greater weight is more 'tough' because it has more strength. There are various measures of strength for metals however, because some perform better than others in different ways. There is tensile strength, compressional strength, and I think lateral strength, but don't quote me on that last one. These relate to the three ways you apply strain to an object - squashing it very hard with something heavy... Pulling on it very hard with something strong.... Or applying force across the mineral structures. It's important to understand that any *metal* is nothing more than a structure of billions of tiny crystalline / mineral structures. Any metal can only be as strong as these structures allow - and applying force or damaging the metal can be accumulative. You might batton your knife on monday, and all will seem fine... But under a microscope, you'd see that you have damaged the mineral structures. On friday you might baton in the same way, with the same woods... And the knife snaps. This is simply because the damage built up, and caused the blade to fail. I hope you find this useful!

Just a couple picky things: generally speaking, rocks don't spark of course, except possibly for pyrite. And the best pieces of rock will basically be chips that have an extremely sharp edge. The sharp edge is key to shaving flakes off the steel that will ignite into sparks. The fracture pattern you're referring to is called conchoidal. It is the classic fracture pattern of flint/chert. Once you see the shiny surface on the chip, you never forget how it looks.

But I believe you must have been testing all the rocks with a piece of carbon metal, RIGHT ? I could not tell but I have never found" 2 rocks that make a spark ". ( I would buy a bucket full, ha ) The spark in " flint & steel " comes off the carbon steel . I have seen NO rocks that " throws a spark. " I will be age 80 soon . I have known many World experts. I will pay for 2 rocks that spark and make fire with natural material. I doubt if my contacts, Cody L, Larry O., Richard Jamison, Jim Riggs , Mors K. ( 4 dead now ) ever made fire with 2 stones.

Good info Larry! That first rock that fell apart is what we call in archaology "fire cracked rock". Hairline fractures happen when rock is heated and cooled. It can happen from camp fires, forest fires, and is often a first clue that there might be something historic or prehistoric there also, a settlers camp or native camp. And also sometimes those rocks that are nice, smooth and shiny on the outside often have what we call a cortex on them, which is basically an oxidized outer covering that develops over time. Those have to be broken open to find the good stuff inside. Roadbeds are often a good place to look since vehicle traffic can pre break open the rocks for your hunting pleasure.

It sparked but chipped easily...thanks again for inspiring me to keep going. A lot less labor and more dependable than the bow drill. Finding the right wood is tough. Everything is rotted or wet.

The closest natural flint to where I live is roughly one hundred miles, but there are flint arrowheads along every river and major stream in this region. I'm not at all a fan of char cloth because all the evidence says the frontiersmen never carried it into the woods, and that only the well to do made char cloth at home, often just to impress their friends. Cloth, cotton especially, was just too valuable to waste this way. Even small pieces of cotton scrap were used to make quilts, and even shirts. Raw cotton was more likely to be used than cotton cloth. Cotton was worth a lot less before it was processed, and no one noticed if you pulled a bit from a cottonfield. And there is just no need for char cloth. There are so many natural materials in the woods that you can use for char that you'll never use all of them. And you won't have to cut up a shirt or pair of pants if you run out in the woods. Well, I gave up on most primitive fires a long time ago. Once I learned how to use them, I went back to matches and lighters and ferro rods. I prefer bow drill and hand drill over flint and steel, when just keeping my hand in. If need be, I can make a fire from these without a knife, and without cordage, though a knife and carry in cordage makes it a lot faster and easier. Solar is nice, but not very reliable. Good to have a lens with you, but it only works when the sun is out, and high in the sky. Good for lighting a pipe during such times, but other than this, I ignore it. Anyway, long ago I decided that when I'm tired, hungry, or wet and cold, I want a fire fast and easy, so out come the matches or the lighter. And likely some sort of modern material such as an Esbit tab wrapped with petroleum soaked cotton. Works wonders for a fast fire, and you can even boil water or fry something just using it.

Hello there! I feel that we need to be very careful what we sometimes say regarding the 'flint & steel' issue. I will often times hear someone say something like, "So, we have to find a rock that produces a spark... " Well, YOU know what that means, and I know what that means, but the newbies out there, wanting to learn from us, may not have a clue yet. So, let's be CLEAR about this SPARK thing. The material used does NOT make the spark. Flint, Quartz or any other material needs to be HARD enough (hardness of '7' or higher) to break off, FROM THE STEEL STRIKER, a teeny-tiny sliver of the steel, which when it hits the air, oxidation takes place, so FAST it causes enough heat to cause combustion. When you use a disk sander on steel, all the sparks flying off is exactly the same as using 'flint & steel', just on a MASSIVE level. So just remember, it is the STEEL that is producing the sparks, not the flint or likewise hitting the steel. Okay_ lesson over. I need a cookie! :-D

I’ve heard that is a good place to get good rocks. I think a lot of the gravel is quarts and in some parts of the country like New Mexico chert common for railroads and driveways.

Hi Larry. Could you do a video on picking out a good piece of high carbon steel to use as the striker? I have 1095 knives and a few "store bought" flint strikers, but a little tour of picking out stock to make perfect strikers would be great. How to pick out the right steel in an urban environment, salvage yard, hardware store, ...etc.? I've seen people argue online that "flint and steel", much like a bow drill set, is a "skill" concept rather than a "gear" concept. As in, you create the conditions in the field rather than pack it in a kit and carry it with you, hence the need for the 1095 knife. I don't really care about those peoples debates....lol...I just want to make a few awesome strikers to have with me and give to friends. Your striker was oxidizing off some really nice sparks of itself and I'm jealous. Lol.
@LarryRobertsbc
9 жыл бұрын
Jamie Hitt I might try and do that, but to be honest most steel needs to be heat treated to throw off sparks. In other words you can find the steel in the field, but most times it won't work. Some good files will work as is, by just filing off the groves. Is that what your asking or do you mean find the steel, then heat treat it to make good strikers?
@JamieHitt

***** I don't know...lol...that's the problem. I guess, I'm just wondering what exists already, like files, that can be used as strikers with flint. I'm beginning to wonder if it is easier to find the right rock than it is to find the right steel. It really emphasizes which one of the two is most valuable in the kit. I'm wanting to be more self reliant than just ordering flint and steel kits online. I really like your video on testing the rocks, but it assumes we already have the steel striker. I could just search up a list, but I thought it might be a good video opportunity for you. I just value your opinion over most others. What do I have laying around in the garage that I can chop up, cut off, or grind down to make a good striker. Or, what already exists in Lowe's that is a perfect striker, aside from files. Something that might already have the shape and size we want.

Good idea. I will try and give it a go soon. Keep in mind (this goes along with the argument some folks have) that old time folks would carry a good striker, but might have to find the stone to strike it with. Nothing wrong with carrying gear. Think about this, would the Native Americans or early people make a bow drill every time they needed a fire or would they make one proven kit, then carry it with them? I understand what your saying and I think it's a good video idea that I will try, but a valuable striker is one to keep and pack with you.

***** I absolutely agree. What I'm aiming at is "where to get one to start with" for those who don't have one. The knowledge of what to look for and where. Then, you have a great piece of kit without having ordered it from a website. Does that make more sense? I guess what I'm saying is....if you did not have a striker...what would Larry do to get one that he trusts to do the job? After re-reading my first comment, it looks like I just want to find one along the way in an urban environment survival scenario, rather than carry it Sorry about that. What I mean is, short of becoming a blacksmith, where should I look for one now without purchasing a premade one from a retailer. Trying to go the self reliance route with this.

Thanks for the very informative demo. Chalcedony including jasper (6.5 to 7. on MOHS hardness scale) is very common in this area. Usually when I collect I am partial to pretty rocks, so I collect lots of red, yellow jasper, etc. but I've picked up homelier chert also, intrigued by its fracturing properties. Will experiment with the sharp fracturing rocks and see what sparks best in my area. I suspect that the same rocks that produce sparks can also be knapped due to the conchoidal (shaped like conch shell) fracturing properties?
