Last month I posted a video on how to start a fire with a ferro rod. It was a quick fun video that my kids and I put together. In that video I used my US Navy Ka-bar knife as the ferro rod striker. The problem with the way I used the Ka-Bar in that video was that I used the blade of the knife as the striker, and that prompted a comment from one of the users on Reddit that using the blade as the striker will dull or ruin the blade.
The reason I had to do that was because of the black coating on the Ka-Bar blade. The coating makes it just about impossible to get a spark from a ferro rod off the spine of the blade. Still though, the Reddit user was right, it's not a good idea to use the blade for striking a ferro rod.
Because of that, and because I love my Ka-Bar so much I decided to modify it a but. I mean, Ka-Bar's are some of the best knives ever made, so why not try to make it work as your goto survival knife right?
What I did was take a file and I filed off a small section on the back of the spine for use as a striker. It is a very simple modification, and it worked like a charm!

As you can see after filing off some of the coating it works fairly well as a ferro rod striker. If you want to do something similar just make sure to keep that part oiled, or put a dab of gun bluing on it to keep if from rusting since a Ka-Bar is made out of carbon steel instead of stainless steel.
EDIT: I went a step farther and used a grinder to make the area on the back even better for use as a ferro rod striker. Check out the updated video:
