Swiss Army Stove The Swiss Army Ranger Stove is without a doubt one of the original “ultra light” cooking options. Compact, versatile, and easy to use, it continues to be a quintessential part of the classic kitchen kit. The complete package fits nicely into many of the “one liter” bottle carriers and pockets commonly available. Dry weight is a mere 15.2 ounces in the stove’s stock form, not bad for a pot/cup, 1-liter bottle, and stove. For comparison the weight of an empty Hydroflask 21-ounce bottle is 20.9 ounces. Additionally, if weight and space are of primary concern, one can forgo the bottle altogether and stuff the stove full of provisions and/or fuel. Without any bottle, the stove and cup/pot weigh in at 9.9 ounces. All testing was conducted outdoors, in the shade, on a windless day with an ambient temperature of 40°F. The water used in the test was left outside overnight to simulate realistic camping conditions. During the test, the included pot/cup was filled to the half-liter line. Testing was performed three times with each type of fuel, and the final score is an average of the results. Trioxane / Hexamine Tablets Trioxane was the fastest heating fuel tested, and brought the cold water to boiling in a mere six-and-a-half minutes. This was quite surprising considering this fuel’s dim blue flame and minimal ambient heat. The downside to trioxane is it’s highly toxic nature, the aforementioned low ambient heat and light, and the extremely nasty mess it leaves behind. It is strongly recommended that you wash your hands after handling the fuel, and it would be a good idea to place the tabs on a sheet of foil for easier clean-up. Two bars of fuel were consumed by each test with consistent results: the first bar heated the water hot enough for tea, but failed to reach boiling; and the second bar sent the water into a Jetboil-gone-mad style, dangerously violent boil. The tablet-style fuel is much better suited to this stove than the bars. Wood, Twigs and Grass A combination of twigs and kindling (grass) wrapped up in palm-sized bundles was used for the wood test to ensure a good, consistent burn. This is the recommended method of fueling the stove when using wood as it generates an optimal amount of heat without overheating the stove, burns fairly efficiently, and is easy to clean up. Boiling was achieved in a… NSFW · Explicit
