    This is a great fire steel, I have used it multiple times and it works great every time. Delivery was really fast and the whole experience with Fire Steel was great. I would order again if needed

    I bought a couple extra to have on hand or give as gifts. I have purchased this product from this company a few years back and used it for camping. Love it!

    Firesteel Bunker 4.0 the Best

    Posted by David on Oct 20th 2019

    The scraper and rod are excellent. The magnesium rod is an added bonus for getting my fires lit. Throws tons of sparks.

    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.
