Many fixed blades and folders sport a glass breaker or impact point. It is a nice accessory. All across America people are discovering a need to suddenly open a car window to rescue a child or pet. On a 70 degree sunny day, temperatures in a sealed car can reach 120 degrees. Following an accident, breaking a window may be the only way into or out of a car. Most knives put the impact point on the back of the knife where your hand wants to sit. This can limit the amount of force you can apply to an open knife because the point digs into your palm. The ST karambit will have the impact point situated on blade spine on the front of the knife for easy use with the knife closed.
There’s still talk about an auto with a hidden split bolster opener. Made here in Ohio. How cool would that be?
I’m so excited about seeing these, maybe by the Blade Show? Who knows.
