Have you started a fire with the magnifying glass?

Very interesting question, potentially lifesaving. The short answer: you cannot. I tried it, at about noon, on white newsprint. It would not char the paper. However, on areas of black ink, it would burn a hole through the paper in 5 to 10 seconds, but I could not get a flame. I tried blowing on the paper, and tried multiple thicknesses of paper, all to no avail. The lens on the Swisscard is about 5/8". I tried the same experiment with a 3" magnifier, which collects about 23 times more power. I could rapidly char and burn through multiple sheets of the newsprint, but found that it was very difficult to get the paper to burn. It seemed to work best with the paper vertical and modest blowing. I could only get a fire started in about 1 in 10 attempts. I then tried the cardboard from the tube inside a roll of paper towels, using the 3" lens. This combination could quite easily start a fire. However, the Swisscard could not char the tan surface of the cardboard.

I forgot it was in my wallet and they took the knife at the airport. They want over $10 with shipping from the swiss website. Any cheaper suggestion

To 801Jones, perhaps if you spent less time mocking and more time reading, you'd see that what the person is asking is where can they get a replacement for just the knife that was taken. You can't get that on A-M-A-Z-O-N as they don't sell this part separately. My old stand by for stuff like this is ebay. I found someone who is selling the knives in packets of three for about $13 but at least you're getting three and if it you forget to remove it again, you'll have spares. The seller was only selling used ones which made me thing he's probably getting them from some guy at TSA who confiscates them and then turns arounds and sells them (LOL) but hey, better than nothing.
