Firefighter / rescue tech feedback - we use these on MVA’s all the time and they work consistently. It does depend on tempered (side/rear) vs laminated glass (front). Whoever posted about the corners is spot on, that has to do with the amount of “give” in the window - the bottom corners seat much tighter and typically one punch will shatter the glass. Completely agree with consistent location too, key ring in ignition / visor / pockets, all good ideas. Just don’t want them prone to becoming lost during a collision..
Just a couple of tips: These and other glass breakers usually work better in the corner of a window and a little worse in the middle of the side windows. I don't understand completely the science behind this; but it has something with the resonance of the glass breaker on the window and the tension in the glass itself... I heard for that reason many expert advise to use a corner of a larger window (about 2 - 4 inch / 5 - 10 cm from a corner) BTW this works only on the side and back windows of a car and not on the front windshield !!! The side & back windows are specially designed to shatter into fine particles to prevent serious glass injury in case of a collision. IMPORTANT note: please close and/or cover your eyes to protect them from these glass particles while breaking the glass with a glass breaker! Don't bother with the front windshield in case of an emergency because it is a very strong layered glass to protect the occupants of the vehicle from objects *(for example stones on the highway) that could hurt the passengers if that object flew trough normal glass.
It's a little larger and heavier, but any professional will tell you that a spring loaded center punch is the gold standard for breaking tempered glass windows. Whatever you use, a bottom corner is the best place to strike the window.
been thinking of picking a couple of them, seems they work well, for now i have a """tactical pen""" if you want to call them that, with a tungsten carbide tip on one end, it works, two tools in one
I find these can be abit awkward to use...yes small and handy..I have a few old style (orange ones) they work well! I carry as edc a pair off paramedic style scissors..with built in glass breaker,glass cutter and ring cutter.
Mine hangs from the rear view mirror so my passenger can reach it if I’m disabled in an accident. I used to have one of the hammer style breakers but when I rolled my vehicle it turned into a projectile so I stopped carrying it and looked for something else.
I wonder if the door and glass being underwater would suppress the impact making it harder to break, or work to amplify the impact making it easier to break. Come on Ian, we need another door, a hot tub and a repeated test 😂
While very useful, I would strongly advise that if you're able to carry a knife, you carry one with a glass breaker in it. If you get into an accident or there is another emergency situation, it is far more reliable to always have the glass breaker/belt cutter attached to your pocket where is will always be in the same place

That’s great advice thanks for watching and sharing your wisdom!

Great advice thanks so much!
Great video. This tool looks perfect. I wear an elastic bracelet with glass breaking bead on it, but it is probably not as good as the ResQMe
Interesting! I’ll have to take a look at those

Loved the video re bathroom kit but could find the promised link nowhere
In the description. Click “more” below my video.
Thanks for checking!
You bet!

They are ok but these are so easy to use. No motion of the arm required!
@@iansedc yes, easier to operate in a confined space, good thing to have, thanks for the video

Oh wow good point!
Excellent
Thanks!
nice work thanks
Thank you too!

Haha, I love your enthusiasm! I'll make sure to add a hot tub to the next video ;) Who knew breaking doors could be so much fun?
@@iansedc Gangs, especially in England, would use the ceramic bit from a sparkplug to break into cars.
@@CanadaFree-ce9jn Yes that is common.
