Sullivan tracked down Michel and proposed a partnership to develop the saw for the construction market. Although the tool wasn't much good for harvesting sugar cane, it captured the attention of Joseph Sullivan, a Chicago businessman who happened to be traveling through New Orleans. That tool used a motor from a malted-milk mixer mounted on a machete handle and a wormdrive gearbox to spin a tiny 2-inch blade. It evolved from a sugar-cane saw that Edmund Michel invented in Louisiana in 1921. You may have heard it before, but here's a recap: The Skil 77 - the same model wormdrive that today captures nearly 90% of the wormdrive market - was invented in 1937 by Edward Sterba of the Skilsaw Company. The division between East and West is a classic tale. Whenever I unpacked my saw, the other carpenters raised their eyebrows, or laughed out loud, making remarks like, "Why don't you just grab a chainsaw while you're at it?" Rarely did I see another wormdrive on site when I did, it was on a timber-frame or commercial site. Model 1677M (above right) has a more traditional setup and shares a housing and rear handle with the West Coast favorite, Skil's model 77.īut my inline-centric viewpoint changed in 1980, when I moved to the East Coast and began working mostly for remodelers and as a finish carpenter.

Bosch claims that the design gives users the benefits of a wormdrive in a platform closer to what they're accustomed to. Bosch has the industry's newest inline offerings and is attempting to convert sidewinder users with its top-handle model 1678 (above left).
