Performance notes
The combination of a 17.5 inch footprint and 27.5 pound weight points to a dense, substantial product rather than a single light hand tool, though the listing data does not confirm whether that weight comes from one tool or a multi-piece set. Buyers should treat the weight as a rough indicator of build heft rather than a spec of the tool's function.
