Fast delivery, no waste of material in the packaging. Excellent. Unfortunately, I of course could not test whether the knife for safety belts in emergency cuts well. The blade cuts well, my friend has cut unfortunately the finger, so the blade is working properly * g * Visually, the knife acts of high quality. And really everyone should have something like this in your own car. Reason of the purchase was the experience of a fellow police officers view which had with a woman in a crashed car burned because there was no way to free them. With this tool, which has a peak similar to that of an emergency hammer on the bus should something like this can be prevented in the future hopefully. I am happy.
