I've pretty much tried em all, the gerber fixed, the folder, a traditional bucksaw, a home-made buck saw, a home made saw using sawzall blades, both pocket chainsaws, and a Sven saw. I've really enjoyed using the Sven saw because it uses so little energy to get er rippin. The Sven saw folds down and sheaths the well designed blade and comes in two sizes, the 21 in. and the 15 in. They both weigh around a pound and are nice n safe to pack. they go great in a canoe. I never really cared for the pocket chainsaws because you have to use two hands and you have no control, i neve liked the folding saws because they are bulky and dont cut as well as the Sven. Just figured I'd pass along my two cents and also see what others are using.
my only beef with this saw is the fact that since it's a triangle.......if you are too deep into a cut, the point of the triangle limits the cut stroke. But it really isnt too prevelant when cutting wood in Alaska for a camp fire or to build a canvas tent frame.
