Expert Opinion
Professional reviewers and editors consistently rate the Klein Tools 31737 highly, noting its innovation in storage safety and cutting efficiency. Editors highlight that the blade is as sturdy as fixed-blade alternatives while offering the convenience of a folding design. The product is praised for its bidirectional cutting capabilities and the utility of the 125-degree lockback for confined spaces, with trade sites rating it between 4.5 and 4.8 out of 5 for its ability to eliminate tool bag damage.
What Users Say
Everyday users and contractors express strong satisfaction with the product's ability to cut drywall smoothly and protect tool bags from damage. Common praise focuses on the comfortable grip, the utility of the 125-degree angle for corners, and the convenience of the tether hole for ladder work. Recurring complaints involve the initial stiffness of the lock mechanism, which users note loosens over time, and limitations when cutting thicker plywood or needing larger cut diameters.
Common Complaints
The folding lock mechanism is initially stiff and requires a break-in period. The blade binds or dulls faster when used on thicker plywood. The 5.2-inch blade length is considered too short for making large holes compared to fixed saws.
