Hi people! I am new to the Forum and also Canadian Eh! Most Coleman products are classed as intermediate usage. The exceptions are Naptha burning appliances which will usually fire up well below minus 35C. This would place them in the extreme application category. Propane and most other gases turn to liquid in extreme cold and will not flow or atomize to allow combustion.<br><br>Older Coleman products are a lot more durable and dependable then the newer stuff made after 1988-89. If possible get older products and rebuild them.<br><br>I pesonally think that K-Bar USMC is the best bang for the buck in a long knife. It is full tang, leather wrapped handle so that your skin won't freeze to it. Sharpens extremely fine, holds the edge well and it is big enough to handle most jobs.<br>I have attached a BF blade and pouch to the bottom part of the K-Bar sheath. Serves me well.<br><br>One other note. Try and have all of you battery operated survival gear run on the same size batteries. AAs run my CB, VHF, AM-FM radios, flashlights and strobelights. As power is used this will allow you to use your batteries for the highest priority.
