Not sure why that photo is rotated... Anyway, the tinders shown are Jute twine, a Wetfire cube, soem dryer lint, a piece of Tinderquick, and the big white blob is a Petroleum Jelly Cottonball (PJC).
I managed to get them all lit with the ferro rod. Some were way harder than I thought they would be. I found that I needed to scrape shaving from the Wetfire cube to get it to light, some of the other tinders were already out when I got it going. It did, however burn the biggest and longest, all that flame on the upper right of the phot is from the cube. The jute twine and dryer lint took the spark well but burned quickly. The Tinderquick burned so fast it may already be out in the photo. The PJC did as well as it always does, a good burn with plenty of time to get what you needed lit.
For me, I'll keep packing Wetfire cubes in all my packs and kits because they really are good at fire starting. They take a flame from a lighter or a match super easy but if you are using a ferro rod you WILL need too scrape it up a bit. Also the PJCs will also stay in all my kits. They last forever, pack very small and have uses other than as a tinder.
