Product Description

Product Overview: The Ultimate Tool Ruler Born for Safety and Practicality

This is a "ruler" that goes beyond traditional concepts. With the craftsmanship of tool-making, we have redefined the ruler. It is no longer just a measuring tool but an all-in-one device integrating emergency window-breaking,function testing, and outdoor practicality. Whether placed in a car as a "guardian of life," or kept at home, in the office, or in an outdoor bag, it serves as a solid backup for you to deal with unexpected situations.

Core Selling Points, Unmatched

Superior Material and Craftsmanship: Selected high-quality stainless steel undergoes a complex double quenching process, enabling the ruler body to reach an extremely high hardness of 60HRC, comparable to some professional tools. This ensures it will not roll or break when performing tasks such as window-breaking and smashing.

Striking Size and Weight: With a total length of 53cm, a thickness of 5.0mm, and a weight of approximately 552g, this thickened and weighted design gives it strong impact force and a stable grip, delivering powerful performance with a single strike.

Truly Multi-Functional Integration

Car Window-Breaking: In critical moments, use its solid edges to strike the four corners of the car window forcefully, enabling instant window-breaking for escape.

Performance Testing/Outdoor Tool: It can be used for wood-cutting, brick-breaking (for demonstration purposes), or as an emergency tool for outdoor camping.

Accurate Measurement: The clear scale marks still retain its basic measuring function as a ruler.
