It was a sunny afternoon when the package arrived, so I wasted no time and ran outside to try it (read: didn’t read the instructions). The medium-size fixed blade knife was snug inside its tan leather sheath. I opened the container of char cloth (burned cotton) that was enclosed in the set. Being familiar with optical fire making, I knew that all I had to do was line up the flat side of the shiny, shallow parabolic mirror so that it was perpendicular to the setting sun. I set a tuft of char on a nearby stone wall and rotated the knife handle until I saw a brilliant spot of light on one of the stones. I carefully moved the bright spot over the char, which in turn began to smoke immediately and effusively. I was thrilled! I felt like I was back in my unsupervised childhood torching ants with a magnifying glass. The reflective surface on one of the knife’s handle scales is able to focus the sun's energy to a blinding pinpoint of light, which is more than enough to ignite combustible materials, especially dark-colored ones like char cloth. As a bonus, the blade is of good quality steel with a full tang and a keen edge right out of the box. After reading the instructions, the small hole in the handle made more sense. It’s designed to hold a stick onto which you affix your tinder, making fire starting even easier.
