Here are some examples you can modified the Fire-Steel to more practical use.
Remove the useless handle and fire striker, use a small length of Paracord outer shield and wrap it around with a 1 inch Duct Tape. You can wrap more if you want so that your emergency duct tape is on your firesteel. I have used half a meter of red duct tape which will be used for trail markings, at the same time the duct tape makes a practical handle that I can use for repairs.
Here is another option for a Leatherman Survival Kit. With the Firesteel handle removed, I can slot the firesteel into the side pocket.
2 x band aid, 1 x cotton bud, 2 x iodine stick, 10mtrs inner Paracord yarn, 1mtr Paracord, compass, tinder, firesteel, paper, signal mirror, whistle, mini-flash light.
