I always carry a magnesium fire block with striker on my key ring along with a Mag-Lite AAA Solitaire. I also carry a 3 blade Old Timer (Schrade) knife that I hae had for about the last 22 years( father gave it to me on my 8th B-Day). With those 3 things I am pretty certain I will not get into too much trouble that I cannot get myself out of. And before anyone says anything, yess I do always have it on me when I am away from home. It goes into my pocket as soon as I put on my pants. The only thing that might change is the type of knife I am carrying but I only use carbon steel blades so I always have a strikable metal with me.<br><br>
