BWJ Ultimate Camp Saw: Trust me on this one, I have tested just about every camp saw on the market and my search is over.  I have relied on the Boreal 21 for all my larger firewood cutting for the last three years and it has ripped through 3-6” thick pine and beaverwood like a champ.  The 18” blade swings out and locks down with a pivoting action, all in one motion.  The unique design has zero loose parts to lose or assemble and the locking mechanism has such tight tolerances, the blade is held super-tight preventing all twisting and binding while sawing.  All my Grand Slam Guide Service clients love this saw so much, I rarely get to use it.  1 lb 5 oz
