  1. Nothing but the best

    Posted by tefana on May 9th 2018

    Once again, it did not disappoint me one bit. Not the first time that I buy firesteel from them, and definitely will not the last time. Except it might take me longer to go through the half inch by 5” lol. But like the Godspark, it delivers a shower of sparks, enough to light up any dry tinder or feather sticks u want. Even my 11 yr old boy swears by it and always try to find a way to use his firesteel to light up any bbq grill he can. Anyway, this product is definitely something to get and add to any prep bag along with the knowledge on how to use it.

  2. Order firesteel bunker5 to France

    Posted by Richard on Jul 22nd 2017

    Hello, I congratulate firesteel.com for their professionalism, the quality of their service and of course firesteel!!!

    Thanks for the commercial gesture (magnesium offered because of being international client) as well as the offer of delivery solutions for europe ... (info: delay more than that of japan in import).

    Indeed, I ordered from France because I was looking for a precise model: a larger stone and especially providing a sheaf of sparks of quality ...For comparing models, light my fire etc, whit out hésitation, now I can guarantee that Firesteel.com offers the best stones on the market!

    Congratulations,best regards.
    Richard from France..

  3. Awesome product

    Posted by Matt on Feb 3rd 2017

    This is exactly what I have been looking for. I get more sparks, Hotter sparks, and longer burning sparks than I did with my cheap ferro rod. I prefer using fatwood as my go to tinder, and this ignites it easily, and consistently. I recommend holding your knife 90 degrees on your fatwood, and scrape it into finely shaved layers. The Firesteel will then ignite that stuff with a fury. Thanks, Ron

  4. Real Deal

    Posted by Ray on Jan 18th 2017

    THIS IS A FERRO ROD!!! Great quality and its real ferro not the cheap crap, casts tons of sparks, this is the BEST

  5. happy camper

    Posted by paul lewis on Apr 10th 2016

    First off let's start with the packaging I absolutely love the way fire steel uses the packing slip and instructions to pack the product this saves so much waste and cost. As for the product this thing is huge and throws amazing sparks. I've used the small cheap ones you can get at some of the big box stores but they don't even come close to the amount of spark or temperature in my honest opinion. I bought the ones with no hole and put deer antler handle on it. Needless to say I love the whole experience with fire steel from fast shipping to great packaging to great product. I will be shopping here again and added the site to my favorites.

  6. Great firesteel.

  7. Bug chunks of burning metal

    Posted by Peter on Jan 30th 2016

    I have a collection of fire steels from over the years. I was able to get sparks, including from the Scandinavian brand, but found matches to be much more reliable. I started looking for a fire steel that could provide a strong enough spark to light something besides cotton balls on the first or second try. The firesteel.com fire steels have that capability. And the 5 inch by 1/2 inch diameter rod just makes it that much easier by putting out multiple chunks of burning metal that last for two to three seconds.

  8. Great, Great !

    Posted by Unknown on Dec 6th 2015

    Outstanding customer service.
    Great product.
    Can't go wrong shopping at Firesteel.com

  9. Perfect

    Posted by Matt on Aug 18th 2015

    Excellent fire steel. This 1/2 x 5 will be easier to use in cold weather.

  10. High Quality Ferrocerium Rod

    Posted by Unknown on Mar 19th 2015

    I have always carried some form of flint/steel or ferrocerium as part of my wilderness kit. I have tested this Firesteel 5" many times since purchase using natural tinders & carbon-steel knife in various weather conditions & it is producing enough high tempertature sparks to ignite even in a damp environment.

    As well, it would appear to be going to last for a long time even with daily use. This is the best ferrocerium I have come across & aside from seeming very easy to use regularly under normal conditions with good tinder, I feel I also have a high quality tool to handle emergency scenarios.

    Lighters & matches are not always reliable in certain weather. Although I carry several mechanisms for fire starting when I go out, the Firesteel will likely be the number one choice in certain emergencies as I know it will be reliable in situations where I am in bad weather & may be under stress & since it can ignite many natural fiber tinders if necessary.

    Lastly, it's compact enough to carry in your survival kit so it's with you at all times. Very good product. I will likely be buying more as backup & for family to carry. For me, less than 5" might be a little less effective. Longer would be fine but then you may be starting to get into the portability tradeoff.

  11. 1/2"x5" ferro

    Posted by Unknown on Mar 13th 2015

    this product is truly awesome.... none any better and i've used many

  12. I'm the Firestarter!

    Posted by Unknown on Jan 15th 2015

    What's big and starts fires? This thing.

    In short, it works.

  13. Ya Get What You Pay For

    Posted by M on May 7th 2014

    With other varieties of similar needs and use, I've had them literally break in my hands, after using only a few times; either the actual flint or break from its handle. After a good amount of searching and researching I found a true higher quality in FireSteel.

    Having "bear paws" I've tried, with great ease, making fire! I've tried from dried grass to leaves, newspaper to notebook paper, various bark to pine needles and made fire every time. However my need was for a length of 2 1/2 inches, even after carefully cutting in half, with such a small area to work with fire was made!

    In one word "Excellent" or even "Outstanding"!!

    Like the old saying "Ya get what you pay for"

  14. Simply the BEST

    Posted by Michael on May 1st 2014

    I have used all kinds of fero rods. These are simply the best and the only ones I purchase any more. Don't waste your time with others. Great product, good price. Bottom line...I trust them.

  15. Great for kids, cubs scouts and scouts.

    Posted by Rob on Apr 3rd 2014

    Great product, and if you are teaching kids (in my case cubs and scouts) this size is easy to grip for smaller hands. The sparks are large and bounce all over the tinder and remain burning for a split second. We used a closed Opinel knife for scraping the steel, good solid edge and easy to hold, and since it has a locking blade it is approved for cubs and scouts. Firesteel shipping was fast.

  16. Great product!

    Posted by Kevin on Mar 28th 2014

    Great product and fast shipping! Throws a huge amount of sparks which has helped ignite marginal tinder bundles. Couldn't be happier.

  17. Great quality product

    Posted by Unknown on Feb 19th 2014

    Great Firesteel rod. Extremely hot sparks when scrapped. I will buy again when this rod runs out, which will be awhile.

  18. It's in the DIFFERENCE

    Posted by Kenny on Jan 19th 2014

    WONDERFUL products, let's off burning balls of molten material while others makes sparks. Comparing other brands of firesteels is like comparing the amount of sparks you get when striking metal to concrete. When striking the Firesteel.com firesteel it's similar to scooping up molten lava and putting it in your tinder bundle. It sticks to the scraper and burns away at it while you try to figure out what to do next.

  19. This firesteel will last 5 lifetimes!

    Posted by Daniel Schwemin Jr on Jan 5th 2014

    I ordered this because Ron has such a great price. After receiving this in the mail, I was just in awe of how freakin' huge this thing is! Seriously, I don't think I could use this thing up if I tried!

    I also ordered 3 super scrapers and they work amazing and are good quality. They will definitely be in my pack.

    For the price, and sheer quantity of firesteel that you get, I don't think you can beat firesteel.com

    Great product at an unbeatable price! Thanks Ron.

  20. Freakin' HUGE

    Posted by RRM on Dec 18th 2013

    Perfect size for a monster shed antler handle ... why not go for the Bunker! This is not my first purchase from FireSteel.com I already knew the items worked and where shipped quickly. No difference this time around!
