Overview
Klein Tools makes this drywall saw with a rectangular carbon steel blade that folds into a plastic handle. It is a manual saw, pulled and pushed through the board by hand, which makes it useful for outlet boxes, vents and small openings.
The reason to buy is the fold-away blade that travels safely in a tool bag and opens fast for cutouts. The limitation is that manual sawing through large panels takes effort, and the listing does not say how the blade locks open.
Who it's for
Electricians, drywall hangers and remodelers cutting small holes for boxes, vents and pipes will use this most. Homeowners facing big sheet cuts or hard materials like plywood need a larger saw or a power tool.
Pros and cons
- Folds away into the handle
- Carbon steel blade
- Light to carry
- Colored handle is easy to spot
- Blade lock not described
- Handle is plastic
- Manual effort on long cuts
Performance notes
A blade with many teeth cuts drywall on both the push and pull stroke, and the rectangular profile suits starting a cut at a mark. Cutting speed depends on stroke length and how sharp the teeth stay. Gypsum dulls teeth over time, so expect to replace the saw rather than resharpen it.
