Ferro Cerium Flint Rods
Have a look at this video I made on how to get these to spark:
These are sold with a handle for 3 to 6 times the price of the bare rods that I have here. You can make a handle with a wrap or two of para cord and super glue it on.
Common names include: sweedish firesteel, flynt rod or stick, flint rod or stick, fire striker, fire rod, spark stick, match stick, match rod and many others.
I am going to set up a quantity discount on these so you can include them with any knives sold.
These are very light and very durable:
3/16"x 3" rod is .3oz
1/4" x 2.5" rod is .5oz
3/8"x 5" rod is 2.2oz
To use these, there is a technique!:
These will kick out an amazing spark but you have to hold your mouth just so.
There is absolutely a technique and learning curve. It took me an hour of practice to figure it out. If you know how, it will take just a few strokes to have it down.
In short, you have to shave off something like dust or little scraps as you stroke down the rod. (I know). Use the back side of the hacksaw blade, not the teeth side. (actually any sharp edge of hard steel) The sharp 90 degree edge of the back side scrapes off a little dust and that is the stuff that actually ignites. You dont strike it like you would trying to spark flint by smacking it, you push down hard as you stroke down along the ferro rod with the scraper and it ignites the dust/chips/scraps from the friction of the scraping action. Using the teeth side of a hack saw blade would seem to be ideal but it just doesnt work. I dont know why, it just doesnt.
They will work, if they dont for you, Ill give your money back, no problem.
Note: These are not Magnesium blocks where you shave off a bunch of shavings into a pile and then try to ignite the pile. That is different stuff, different technique. You CAN use the ferro rod to ignite a pile of Magnesium shavings though.
Below is from Wikkipedia:
Ferrocerium is the "flint" in lighters, and its ability to give a large number of sparks when scraped against a rough surface (pyrophoricity) is used in many other applications, such as clockwork toys and strikers for welding torches. Also known as Auermetall after its inventor Baron Carl Auer von Welsbach, it is sold under such trade names as Blastmatch, Fire Steel, and Metal-Match.
While ferrocerium-and-steel function in a similar way to flint-and-steel in fire starting, ferrocerium actually takes on the role that steel played in traditional methods. When small shavings of it are removed quickly enough, the heat generated by friction is enough to ignite those shavings. The sparks generated are in fact tiny pieces of burning metal.
Lighter "flint" is composed mostly of an alloy of rare earth metals called mischmetal, mischmetal containing approximately 50% cerium and 45% lanthanum, with small amounts of neodymium and praseodymium. The origin of its easy sparking is cerium's low temperature pyrophoricity, its ignition temperature occurring between 150 and 180 degrees celsius. Since smaller scrapings become better sparks, the mechanical properties of rare earth metals must be adjusted to give a usable material; to that end, at least two strategies have been developed to make such alloys more brittle:
- Oxide - most contemporary flints are hardened with 20% iron oxide and 2% magnesium oxide.
- Intermetallic - in the Baron von Welsbach's original alloy, 30% iron (ferrum) was added to purified cerium, hence the name "ferro-cerium". Iron reacts with rare earth metals to form hard intermetallic compounds similar to those in neodymium magnets; such magnets are also known to generate sparks quite easily when broken.
