A chainsaw that increases the level of operator safety by reducing or eliminating cut through and kickback injuries without impeding cutting operations, and increases operator comfort through ergonomics, therefore extending stamina. This is accomplished by a dual stage multi-hinged bar device that physically inhibits kickback and cut through injuries. The device, which returns to it's original position after cutting, will open up a total of 88 degrees to allow for cutting of items that are larger than the length of the guide bar. Relocation of the handles leads users toward physically holding the saw in such a manner that creates an ergonomically advantageous body position, reducing fatigue and strains. The body of the saw and the bar device will rotate 45 and 90 degrees both right and left while the operators grip on the saw remain in the same position. The chainsaw also incorporates an easy to use chain adjustment.
