I went from 6.5 pounds to 3.5 pounds. The side arms are now only 7/8" thick and the far end stretcher is 1 1/8 with a reinforcer where the 1/2" bolt hole and redundant 1/4" grove for the saw blade are. I rechamfered all the newly cut edges with 1/2" wide chamfers to further lighten the tool and to make it easy to grasp.
