OK, so I have watched a few videos on YouTube today and noticed these people starting fires with ferro rods. I don't know a single person who starts a fire with ferro rods.
Me, when I can. Mostly to stay in practice. Takes longer to set up a fire so most of my friends get impatient.
You need the correct size, I prefer 1/2 diameter. The small ones are just toy's.
Most of the U-Tubers do it to make themselves look cool. In reality its more work and way faster with a lighter. Most of the guys in my group have small propane torch's to start fires with.
What's funny is I have a ferro-rod because I saw others using it. I tried it a few times and now I have 3 lighters that I use. I'm one of those people that just don't have the patience for it.
