Consumer Reports

The Rexbeti Heavy Duty comes with an SK-5 steel blade with staggered, triple-cut teeth, a long rubber handle, and a lifetime warranty. Despite being one of the lowest-priced saws we tested, it performed super well, cutting through a 4-1/2-inch diameter log in 1 minute, 4 seconds. This saw's 11-inch long blade has no trouble shredding through 6 to 7-inch diameter branches. The locking mechanism is bright orange, making it simple to distinguish from the black handle grip, keeping you from accidentally folding or unfolding. For cutting larger diameter logs, the Rexbeti performs well and won't cost you an arm and a leg — as long as you're careful while sawing.
With a longer blade comes less rigidity, which we noticed while testing the Rexbeti. Compared to triangular frame saws which provide a lot of support for the saw blade, the Rexbeti's blade doesn't quite have the stiffness necessary to cut bigger logs. That being said, it is rigid enough to make the cut, so long as you focus on starting your cuts straight and plumb. It probably isn't the best saw to take on overnight backpacking trips due to its weight and bulk, but for car camping or yard work, it should suit your needs very well.
