It surprised me to that the Spark Lite had an NSN No, do NSN items get tested in the real world? Or does the item just go through a cataloging process.
The US military has been using the Spark Lite since the late 1970's and it has tested many times, including in Survival Schools in Alaska!.
I've seen persons with hypothermia who could not use any thing to start a fire.
Breaking News! Oak Norton and Four Seasons Survival will be bringing to the the market within a few short weeks, some aluminum Spark-Lite's with replaceable flints! After using some of the previously designed brass Spark-Lite's in all weather conditions, I'm looking forward getting my hands on these new Aluminum Spark-Lite's. The new Aluminum Spark-Lite's come with an allen wrench and 1 spare flint along with 8 Tinder Quik in the familier blaze orange plastic case.[b][/b]
