The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, Klein's 38660 curved-jaw locking pliers earn praise specifically for two things that r/Tools threads keep returning to: a markedly better adjustment screw than Craftsman or Irwin, and a pinch-free, lever-less quick release that several community posters describe as more solidly built than competing designs. The 4.7/287 Amazon signal corroborates the community sentiment. One r/Tools thread directly comparing Klein and Craftsman straight-jaw locking pliers concluded that while Craftsman wins on grip comfort, "Klein's adjustable screw is superior." Other r/Tools discussion on high-end locking pliers calls out that on this style of tool, "the unlocking lever works better, the little leg doesn't pop out when you open them, and they're more solidly built" than entry-level options.
What reviewers liked
- High-trust r/Tools threads specifically praise Klein's adjustment-screw design over Craftsman and Irwin
- Pinch-free lever-less release praised in community discussion
- Solid 4.7/287 Amazon verified-purchase signal
- Curved-jaw 7" and 10" sizes cover the most common use cases
Where it falls short
- r/Tools commenters note current Klein isn't the USA-made tool it used to be
- YouTube comparison reviews suggest several brands at this tier may share OEM factories
- Only two pieces, so no long-nose for detail work
- No straight-jaw option in this specific set

The trade-off, as one r/Tools commenter on Klein bluntly noted, is that current Klein locking pliers don't have the made-in-USA pedigree some shoppers associate with the brand, and a few YouTube comparison videos suggest several brands at this price point may share factories. For a 7" and 10" curved-jaw two-pack at under $30, though, the trust-weighted signal is strongly positive.
