    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.

    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.

    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.

    Perfect for Novice "Firestarters"

    As a beginning camper and over 60 years of age, the Firesteel is easy to use after a couple of practice sessions. Go ahead - try it - you won't be disappointed!

    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!
