This knife is worthless: do not waste your money. The "window breaker" will fall off, as other reviews note. I doubt that the knife in general could withstand the shock of trying to break a window. The blade is weak and construction is poor: 2.5" total blade length, one inch of which is serrated and totally useless. The liner lock is weak and the thumb studs to open the knife will also unthread themselves and fall off. Even as a free promotional "gift", this is a dangerous tool to think you can rely on it.
