Thatīs quite important information. I should check mine cube inside the Strike Force. I just left it there without any testing because itīs the only WF cube I have. I might actually replace it with something more reliable. I donīt like that WF changes itīs qualities once exposed to air. I knew it but I thought that it would still catch a spark and burn. I didnīt know that it would be possible for it to become totally useless.
Maybe I will go with combination of candle from high quality wax and/or fat wood plus one piece of TinderQuick.

Thanks for sharing the information about this.
