The Bunsen Burner style table lighters are a fantastic and functional design. These have a chromed-out look with a fuel tank large enough for hours upon hours of use. The operation of these lighters is pretty simple. First you turn the fuel knob to get gas flowing. Then grab the trigger and start the ignition. Just like your grill, this thing will come to life with a healthy little blaze. Then simply adjust the fuel knob to your liking.
