First invented for halibut fishing, then later refined to work with other long-shafted tools, Stout’s BackSaver grip allows you to grip most tools higher on the shaft, reducing the amount of bending required when shoveling, raking, sweeping, mopping, etc. Less bending hopefully leads to less strain and fatigue.
The BackSaver D-handle easily installs with a few screws, so you can easily remove it and move it from tool to tool. Injection molded with ABS plastic, MBS claims the BackSaver never breaks or wears out.
The BackSaver may or may not “put the fun back into gardening,” but it won’t lighten your wallet that much either. It’ll run you anywhere from $8 to $12.
