The Secret Of The Ferro Rod - Who Needs A 90 Degree Spine?


All I’ve ever heard is that you have to have a 90 degree spine on you knife to strike a ferro rod. But, what if you buy a knife without a sharp spine? Or one that has a soft spine and won’t hold an edge? Will I be able to start a fire?!? You could use the useless striker that come with most ferro rods, or carry a piece of a hacksaw blade, but those can easily be lost. Never fear, there are other ways to get a spark.There is a way to always have the capability to get a spark and it doesn’t cost you anything.

Whether it be a woodland or an urban environment, there is garbage everywhere. I can’t remember the last time I was out hiking and didn’t come across at least one pile of beer cans or bottles. Luckily glass is one of the best strikers you can use. As long as there is an edge it will throw sparks.

Another alternative to get sparks is using a rock. A rock with a fine edge will strike a rod no problem. The examples of rocks I use were a piece of chert and rock I found in the woods.

Not having a 90 degree spine isn’t death of fire by ferro rod. Look around at the resources in your area. Glass, rocks, and sharp pieces of metal are all around you. So get out, practice, and enjoy the woods.
