I already have window punches, in Molly loops on the drivers side visor, and on the vest, but in the video, he had gone through the evolution several times, so he had some familiarity or a comfort level, he knew what to expect, kind of, and he already had it in his hand. In EMS and Fire Rescue, I have them in my scissors pouch and turnout pants pocket. We're using it from the other side of the equation, "controlled" patient access and extrication, not inside the car filling with water. I'm thinking the rock hammer, or like, is more gross motor skill, catacholimine soaked compatable? I found a mount that I think will keep it secure in a roll over, (only one way to find out, and I don't want to be that sure), yet easy-ish access. Combined with a military Rescue Tool 511 600 524 6924, with duess (?) key, basicly about a foot long, T ish handle, with a V on the other end with replaceable V blades at the apex. Lite enough to be secured with velcro, stupid simple enough to work. ( the one Colonial Knives sells is made in the PRC, I'd rather have US made, if possible, sources?) Secured to the console by my right knee, and as they aren't vest-able, the rip shears and window punch remain on the vest as back up. Make sense?

ETA: Just FYI, incase yous don't already know, but as the dude in the video discovered, that with that particular design of punch, your hands tends to follow the punch through the glass leading to cut hands. Gloves should be used. Also, in more terrestrial environs, dust masks and glasses/goggles should be worn by rescuers and patients (assuming the patients are not on non rebreathers already) when we pop windows, as glass fragments can be aerosolized, and you do not want to breath them, or get them in your eyes. This is espicially true when sawing the windshield. JMH
