The double-edged blade cuts on the push stroke on one side and the pull stroke on the other. Anyone who has transplanted shrubs or mature asparagus plants knows how handy it is to have a saw to cut flexible roots; this one does it admirably because the pull-stroke side automatically tensions roots, making them much easier to cut. It also has flame-hardened teeth that will endure accidental rock strikes. Of course, it is efficient in drywall work as well; the double-bevelled chisel point is particularly efficient for starting a cut in the middle of a panel.
