Is there any earthly reason someone would use a jig saw to cut a straight line? I'm shopping for a jig saw for when I need to cut a wavy line, or for cutting out plywood patterns. I keep seeing advertised features on these saws such as edge guides and lasers for straight line cuts, and the images shown in the ads show long, straight cuts being made by them. A jig saw is not a tool I'd choose to cut a straight line. A circular saw with an edge guide seems it would be a far better option, if a table saw could not be used. To me, a laser on a jig saw seems to be a worthless feature.
