Product Description

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

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 2.5mm, and a weight of approximately 252g, 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.
