    I Trust These

    Posted by Erik on Jan 1st 2017

    I have a great deal of respect for these firesteels. I spend allot of time in the back country. I always bring Bic lighters etc.. And the only thing that hasn't let me down are the firesteels I carry always.

    Very good product in my opinion. When everything is failing these do not.

    Perfect for regular use.

    Posted by James from Canada on Apr 2nd 2015

    I wanted a big firesteel as my main firesteel that would last for years. The Bunker 4.0 is perfect for this, just the right thickness to length ratio. The hole is just what I wanted because a wood handle on a rod this thick would just be too thick. The Super Scraper provides a great two finger hold and it attached with real paracord.

    I don't trust the quality in any firesteel if it didn't come from, PERIOD.

    Bunker 4.0: Easy, reliable and inexpensive.

    Posted by Bob Puckett on Sep 9th 2014

    This works great. A little dry tinder and I have a fire! Guess I'll leave the unreliable lighter at home from now on. First use in "somewhat less than ideal" conditions lit off quasi-dry grass debris immediately with only one strike. This firesteel continues to both amaze and please me. Well worth the money. (BTW - it does work when wet!)

    Works Great

    Posted by Russ on Jun 30th 2014

    Just picked up one for a 7-day canoe trip. I used it instead of my lighter. It started the fires with ease. Normally just a few strokes. The sparks are hot and started fires quickly.

    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.
