The JawSaw looks like a badass piece of lumberjack equipment; however, you can't expect to topple a sequoia or any large tree while using it. The JawSaw is more like a cleanup tool that takes care of smaller branches.
JawSaw is a product from WORX that runs on electricity rather than being gas-powered. The jaw-like structure on the JawSaw adds safety for the user by allowing him to old the wooden pieces in place. What's really awesome about the JawSaw is that it allows for users to make cuts on the ground without having to bend down or risk damaging the saw.
All of your neighbors will be asking to borrow your JawSaw once they see how easy and efficient it is to use.
