Is writing well in hand. Bolted cap with fixed clip. Cap is plugged back in writing. High quality material and fine workmanship. How important can be a top grip glass breaker was seen recently in the news. A woman had driven her car into a river and nearly drowned, if not 2 helpers were taken from the outside with a large stone, the rear window. 10 seconds later and they would have drowned. The vehicle sank within a total of only 3-4 minutes. The first helper tried unsuccessfully pursue his fists the rear window (all other windows were already under water). Had the 2 helpers no stone found or would not have been helpers on site, the woman had only a glass breaker, as it is installed in the pen can save.
