A chainsaw is a huge improvement over its unpowered predecessor, the buck saw a/k/a the two-man crosscut saw. Yet both have their advantages and disadvantages. The buck saw is fuel-free, but does require you have a guy named Paul help you out (everyone knows that Pauls cut faster than fellows with other names). The chainsaw lets you fire Paul and do it yourself, but you need a supply of gasoline and some maintenance know-how.
Enter Silky's Katanaboy 650, which offers the best of both worlds. It folds up for compact storage, weighs less than three pounds, can go a long time between sharpenings, and has an absurdly long 650mm (25.6") blade that cuts incredibly fast.

While I lament the length/lack of editing of most disaster prepper videos, I can't deny that they offer the most in-depth tool reviews, carefully going over every design detail and comparing the tool to its alternatives:
At $235 the saw costs more than entry-level chainsaws. But if you don't require the production capacity of a chainsaw and are willing to put in some elbow grease, the Katanaboy 650 provides a relatively fast, quiet, fuel- and maintenance-free alternative.
