    Impossibly easy to use?!

    Posted by Unknown on Apr 11th 2014

    I had never used a fire steel before and was shocked at how easy it was to light tinder, even without magnesium shavings. "Seriously? Beginner's luck!," I thought. Then I lit another pile, and another, and another...Once the black coating is completely scraped off, there WILL be some serious sparks flying. Even a novice (yes, that would be me) can get tinder to light on the first or second strike. I was so impressed that I ordered a "gobspark" for a friend and will probably be ordering more as stocking stuffers. What can I say - the thing works great!

    This thing works exceptionally well! Speedy delivery and perfect packaging. I haven't got to use it in the woods yet but I'm having a ball in the fireplace! Thanks Firesteel

    Burns Porcelain Tub

    Posted by Unknown on Feb 17th 2014

    This thing makes huge hot sparks. I tested it into an old cast iron tub and the sparks actually left burned indentations in the porcelain coating. I think it will do fine.

    Just received the firesteel. I have not had a chance to use it yet. I cannot believe the large size. This steel should last a long long time. Very pleased with this steel. I feel certain it will work just fine for starting fires.

    best firesteel money can buy

    Posted by Dan high peaks, Adirondacks on Oct 6th 2012

    This is by far the best firesteel out there. I've tried most and none can hold a candle to these so easy to strike and when they say gobs of sparks they mean gobs of sparks - it looks like the drips that come off when using a cutting torch but about 2000 degrees hotter!

    First time ever to have fire steel

    Posted by Unknown on Jul 26th 2012

    was excited to give these a try. Man what a deal. I for sure will not be with out fire ever again. EXCELLENT SET IMO . AS time moves ahead I will have to add the longer fire steel for future. not that I think will ever need it but just nice feeling to know I would have it . No sense of false security with the FireSteel Bunker Junior with Scraper Lanyard and Magnesium . Service was perfect and delivery came in a very acceptable and timely manner. Merchandise packed well in nice container.

    Massive performance from a massive steel!

    Posted by Nick D on May 20th 2011

    There's nothing delicate about this bruiser. This steel will perform under the harshest conditions. It literally throws showers of sparks and will light almost any tinder on the first stroke! Designed to give you thousands of fires, the Bunker Junior will not let you down.
