I've waited a while to post up this one since it was just a concept until I could really shake it out off-road. I am pleased to say after 2 months of driving and bouncing around on trails, highways and malls this is working as intended.
This is my escape tool, a Spyderco Assist knife. Spyderco and Slee Offroad are practically right next door to one another. Two awesome companies that I enjoy. This knife is designed to get you or someone else out of a vehicle, it has four main features that I like:
1. A nearly full serrated blade for cutting webbing (seat belts)
2. A rounded blunt tip so it can be used next to skin without fear of puncturing or stabbing someone.
3. A built in carbide glass breaker that pops out when you grip the knife in the closed position.
4. A built in emergency whistle.
I had kept in it the console top lid for a year or so, but then I got the idea to attach it to the headliner with some Velcro One Wrap stuff and it has worked out perfectly. It hasn't moved a millimeter in two months. I am stoked because it is really secure yet easy to access... even in, heaven forbid, a roll over pinned by the seat belt. I gave my wife and oldest son the rundown on how to use it, and my kid wants me to break a window just to show him how it works!
Anyhow, it is super simple but I thought that I'd add it to the thread.
I mounted it right between the sunroof handle and the front dome lights. I just wrapped it like 2-3 times and popped it on there.
You don't NEED one wrap, just any hook will work, but the one wrap doesn't make the headliner "pick" and get fuzzy when removed. It isn't as aggressive as normal hook velcro.
When you clamp the blade in the closed position this guy pops out, the back of the blade is contoured to fit your fingers and make it more comfy to really get a good grip.
Here's the knife when open, you can see the blade has a rounded blunt tip that you can slip between the seat belt or clothes of someone and not fear hurting them in the process. The LONG serrations are a plus on rope and webbing... other wise I despise serrations on a knife.
