If you're going to EDC a sparker and size is a consideration, you may want to look at a Boy Scout hot-spark. You should be able to get them where they sell other BSA stuff (Surplus shops and hardware stores in my case). I haven't used it side-by-side with a Swede or a Metal Match (I have both) but I have successfully used it on a number of occasions. It's smaller than a house key - should be about four bucks.
