JawSaw: The Chainsaw Re-Invented

A Safer and More User-Friendly Alternative

Our team was motivated to develop a safer chain saw to reduce the potential for accidents and injuries resulting from the exposed spinning chain. We are confident the JawSaw is a safe and reliable alternative to the traditional chain saw and could have a dramatic effect on reducing the current number of chain saw related injuries.

Introducing the JawSaw, an innovative electric chain saw designed to revolutionize the way homeowners approach tree maintenance and clean-up. With its unique features and user-friendly design, the JawSaw offers a safer and more efficient alternative to traditional chain saws.

One of the primary concerns addressed by the JawSaw is user safety. The chain is enclosed by a jawguard, which prevents unintended contact with the chain by the user. This feature significantly reduces the risk of accidents and injuries, making the JawSaw an ideal choice for novice users.

But safety is not the only advantage of the JawSaw. The designers also focused on improving ease of use and adapting the tool to the specific needs of homeowners. The proprietary, patented chain tensioning system prevents over-tightening of the chain, a common mistake made by beginners. Additionally, the self-lubricating chain oiler ensures that the chain remains properly lubricated, a feature often overlooked by inexperienced users.

One of the standout features of the JawSaw is its plunge mechanism, which allows the user to actuate the pivoting blade with ease. This intuitive design makes the JawSaw accessible even to first-time chain saw users, eliminating the intimidation factor associated with traditional chain saws.

Not only is the JawSaw safer and easier to use, but it also offers improved functionality. Unlike traditional chain saws, the JawSaw is designed to operate directly on the ground or pavement, eliminating the need to lift branches off the ground before cutting. This feature makes it the ideal tool for cleaning up downed logs and branches. Additionally, the JawSaw has extended reach, allowing for easy pruning of high limbs.

The development of the JawSaw was guided by extensive research and observation of chain saw users. The designers sought to understand the main applications of chain saws by homeowners and the ergonomic challenges they face. Through field observation and interviews conducted in various regions, including North America, Europe, and Australia, the team identified the strain placed on users' backs when lifting logs off the ground and bending down to cut them. With the JawSaw, this effort is eliminated as logs can be cut directly on the ground, allowing users to maintain an ergonomic upright position.

The JawSaw has received recognition for its outstanding design and innovation. In 2012, it was awarded the Silver A' Design Award in the Product Engineering and Technical Design category. This prestigious award is given to designs that showcase exceptional expertise, innovation, and artistic skill. The JawSaw's strong technical characteristics and user-friendly features make it a remarkable tool that introduces positive feelings of amazement and wonder.

The JawSaw is not just a chainsaw; it is a reimagined tool that prioritizes safety, ease of use, and functionality. With its unique design and innovative features, the JawSaw is set to revolutionize the way homeowners approach tree maintenance and clean-up, making it a must-have for any DIY enthusiast or novice user.
