I was walking down the aisles of one of my local Harbor Freight stores when I noticed the new Icon tool display in among the sockets and ratchets and whatnot. While the selection of Icon tools was still a bit scanty, I was drawn in to examine the breaker bars on the rack. I grabbed a Pittsburgh and Pittsburgh Pro breaker bar to compare them side by side. For such a simple tool, it seems odd that the Pro costs twice as much as the Pittsburgh, and the Icon twice as much as the Pro.
The first thing I noticed about the bars was the hinge. The Pittsburg bar was the most obviously unusual insofar as the business end of the tool is on the outside of the lever. But it was also obviously looser, with at least a dime's thickness of gap between the lever and the knuckle. Inside the knuckle is a spring that keeps the bar more or less to one side. I don'tunderstand the purpose of this design, but it looks like it would tend to focus the stresses on a few points rather than across the whole hinge. The other two bars have the knuckle on the inside of the bar, which splits into a rough Y-shape. While the knuckles of these two 1/2" drive breaker bars were similarly sized, the shoulders and arms of the Icon bar were noticeably thicker.
I'd have to bring my scale to be sure, but it seemed like the Icon bar was just as heavy (if not slightly heavier) than the Pro bar, despite the Pro bar being longer.
