10 Best Window Hammer 2025 in the United States

The resqme Original Emergency Keychain Car Escape Tool is a compact and practical device designed for quick action during car emergencies such as rollovers or floods. Its main strengths lie in its dual functionality: a razor-sharp stainless steel seatbelt cutter that can quickly slice through jammed belts, and a spring-loaded, heavy-duty stainless steel spike that effectively breaks tempered car windows, especially when aimed at the corners. Made from durable ABS plastic with metal components, it feels solid and reliable despite its small size (about 3 inches long and just over an ounce in weight), making it easy to carry on a keyring or inside the car. The bright orange color improves visibility in stressful situations. While it lacks a traditional handle grip, its gun-shaped design allows for a secure hold during use.

The tool's compactness is both a plus and a drawback—it’s very portable but might be harder to handle for users with larger hands or in situations requiring more leverage. It does not include extensive mounting options but can be attached via keyring or cable tie provided, which suits those wanting quick access on a keychain or near the driver's seat. Trusted by first responders and widely used by millions, this tool’s proven reliability and US manufacturing quality add confidence. Users should note it is designed specifically for side windows, not windshield glass, and proper technique is needed for effective use. For anyone seeking a simple, durable, and tested emergency escape tool that fits in a pocket or on a keychain, the resqme offers an excellent balance of portability and lifesaving features.

This tool is lightweight, weighing only 1.27 ounces, and compact with dimensions of 6 x 4 x 1 inches, making it easy to carry on a keychain or clip to a sun visor (accessory pack for mounting options sold separately). Although it does lack a double-headed design, which some users might prefer for additional functionality, the tool itself maintains a high level of practicality. Additionally, while the need to purchase the visor or dashboard clip separately may be a minor inconvenience, its compact design ensures it remains an accessible and essential safety tool.

Made in the USA, this product has been a reliable safety tool for over 20 years. It is ideal for anyone looking to enhance their vehicle emergency preparedness.

However, it's important to note that it can only break tempered glass of side windows, not laminated glass like windshields.
