love the striker in the cap, great idea. i made a spycapsule firesteel like yours, i like the combo. was trying to figure out how to include a striker with it so i wouldn't need one on a lanyard with it, so it would be a totally independent package. this is perfect, great idea.
looks like a pretty nice rig, i like the kydex around the altoids tin, and it looks like you have a pretty good little kit in it too.
edited to add-what are those really thin looking strikers in the bottom two prototypes?
