Hi Pete,<br><br>I personally know the man behind fourseasonsurvival Mr. O. Norton, he's a great guy and he also invented to my best knowledge the Spark-Lite when he was stationed in Vietnam.<br>I have the different versions of the Spark-Lite from the start until the last one made from plastic rather then from brass. The first one was completely different and needed a two hands.<br><br>You can't go wrong with them, just give them a try.<br><br>Best Scouting wishes from Holland,<br><br>Bagheera
