Has anyone used the magnifying glass in a Swiss Army Knife to start a fire? I've managed to do it twice, and it's really satisfying! The sun has to be at its peak, but it can be done. If you haven't done it, give it a go...it's fun!
John, that's pretty accurate...held slightly away, approx. 3-4 cm from tinder, and with the right amount of sunlight it will do it. I have a Swisschamp, Woodsman and Explorer that I love nothing more than seeing the looks on people's faces when I do this trick. That, and saving the day with the corkscrew at a party! Sun? What is this SUN you speak of!? He's a witch. Burn him! With his glass MAGNIFICATION! Sorcery.
