Seoulish Window Breaker and Seatbelt Cutter Keychain,2 in 1

The Seoulish 2-in-1 Car Safety Hammer is a compact keychain emergency tool that quickly breaks tempered car windows and slices seatbelts to help you escape from vehicles in critical situations.

Keep a reliable, easy-to-use escape tool within reach: this compact Seoulish device combines a high-impact window breaker and a stainless-steel seatbelt cutter in a lightweight 2.8-inch housing. Designed for fast, one-handed operation, the tool uses a spring-loaded silicon steel alloy hammer for rapid window puncture and a protected U-shaped blade for safe, effective belt cutting. It’s small enough to hang from keys, clip to a visor, or stash in a glovebox so it’s available whenever you need it.

How fast and effective is the window-breaking function?

The window breaker uses a silicon steel alloy hammer accelerated by a dual-chamber high-pressure spring that releases at over 20 meters per second, delivering a focused impulse to tempered glass. It’s designed to shatter side and rear tempered windows quickly, including under water when immediate escape is required.

• Spring-driven hammer for concentrated impact
• Engineered to break tempered (not laminated) glass
• Performs reliably in submerged scenarios
• Auto-resetting mechanism ready for repeated use

Can one person use it to cut a jammed seatbelt?

Yes — the integrated seatbelt cutter features a sharp stainless-steel blade housed in a U-shaped guard so you can slice through a jammed strap quickly and safely, even with one hand. The open design prevents accidental contact with the blade while allowing you to feed the belt into the cutter easily.

• Durable stainless-steel cutting edge
• U-shaped guard reduces accidental cuts
• One-handed operation for rapid escape
• Built for common automotive webbing thickness

Is the tool easy to grip and store in a car?

Seoulish updated the grip with a non-slip ergonomic texture so it stays secure in wet or frantic conditions. At just 2.8 inches long and 0.06 lbs, it’s light enough to carry as a keychain or secure to clothing, the visor, or a bag without adding bulk.

• Textured, non-slip handle for firm grasp
• Compact keychain-friendly size and weight
• Fits glovebox, center console, or door pocket
• Simple attachment point for clips or lanyards

What safety notes should I know before using it?

The window hammer is intended for tempered glass only and is not effective on laminated windshields. For safety, do not press your hands against the breaker tip when deploying the hammer; allow the spring mechanism to release the impact. The tool resets automatically after each use and should be stored where it’s quickly reachable.

• For tempered glass—side and rear windows—only
• Not suitable for laminated windshields
• Do not press the hammer tip with your hand
• Tool auto-resets and is reusable without manual resetting

Who is this for: The Seoulish 2-in-1 Car Safety Hammer is made for drivers, passengers, rideshare drivers, parents, and anyone who wants an accessible emergency escape tool. It’s especially useful for those who want a low-cost, compact, user-friendly device to keep in a car, stroller bag, or emergency kit for rapid window breaking and seatbelt cutting during collisions, submersion events, or other vehicle entrapments.
