Bigger can be better in some situations, but not always. Sometimes less can be more. The new Worxsaw cordless compact circular saw is a case in point.
At just over 4-1/2 pounds it’s about half the weight of a typical 7-1/4″ (and even a 6-1/2″) circ saw. Which means it can be more easily used one-handed and fits better in tight places. If you have a lot of cutting to do it’s less tiring to use, and for smaller hand it’s a better fit than a large circ saw. True, it doesn’t have the cutting capacity of a larger saw, but it can still dice up 2X stock at 90°. Like all 4-1/2″ circ saws it won’t cut a 2X clean through at 45°. You can easily finish the cut using a handsaw. I like having the blade on the left side as it makes it easier to follow the cut line.
