You can probably get a larger firesteel than a BSA Hotspark in an Altoids kit, if the kit is firestarting stuff only. Don't forget to put some kind of scraper in the kit, even if you normally carry a knife an plan to use that. Add some " can't blow 'em out" trick birthday candles as well. A small fresnal lens is probably of limited utility in firestarting, but why not put one in anyway? I found one cheap in a bookstore - it was in with the other paper bookmarks - I chopped out the center of it to make the fresnel lens for my kit. How about one of those very small tubes of bicycle tube repair glue? Burns like crazy. A small hand pencil sharpener (like schoolkids have in their notebooks) can be used to shave tinder flakes off of sticks. Cut up an old bicycle inner tube into wide bands, and stretch a bunch of these over the outside of the tin. They also burn like crazy and will keep the tin closed. Strike Anywhere matches are in all the grocery stores in my area. Dip the heads in melted candle wax to help water resistance. For sure the Bic lighter. Probably the most subject to failure of all things in your kit, but if it works it would be fastest/easiest. An Exacto Blade might be useful for shaving tinder since a regular sized knife won't fit in an Altoids tin (might even work as a firesteel scraper as well). I would cut down on the quantity of matches that you are planning ... to make room for other alternative firestarting items. I'd rather have a lesser quantity of each item, but more choices. A second form of ready to go tinder to suppliment your vasoline/cotton would be nice as well. Check sports/camping/surplus stores for other waterproof tinder options. A Spark-Light might be useful as an alternate to your firesteel (also comes with tinder - there's your backup for the vaso/cotton).
