You're still going to get some serious internal damage from bullets hitting that suit though. The metal won't enter but the force is still there. And Chinese 'smart' watch designed for cheats... says it all really.
6:48 Flick knives are illegal in the UK. I imagine this will still be the case regardless of where they're kept. The first shoe dagger I ever saw was Rosa Klebb's in the James Bond movie "From Russia with love". 1963. ......which funnily enough is on ITV4 next week.
@@Another-Address I never liked the idea of flick knives being banned. Many a time I would have found a little one useful on my keyring, to cut open a parcel, string or on some such occasion when I've only one hand free.
lol, I bought a cheap plastic pair at a kids toy shop at the mall for like, $10, $20 at the most. So they added an angle to the glasses and made them 10x more expensive. Cool!
I bet a person would get some serious brusing. It might stop a bullet but that bullet hits over a rib it will probably at least be bruised and possibly cracked.
@@chrisk.1539 I saw a ballistic material demonstration over a block of clay. The transfer impact could only be a certain number of millimeters in depth. The US government said 44mm, which is alnost 2 inches. The material they showed handled most handgun rounds at less than half that. They did not shoot .44 magnum at it. They did shoot multiple .45 ACP in the same spot with no penetrations through the vest. Still going to hurt but better than dead.
Maybe like be a spider man up the side of a high rise and spy on people or escape from someone chasing you on the ground? But then they could shoot you IDK , and like that bullet proof suit, the shooter could just aim for the head right? I just use foil to wrap my phone and credit cards when I'm traveling im too cheap.
@@tanucci733 , it's probably the specific angle, thickness of material, etc. If I understand correctly, you can patent something if it's just different enough from something else. It seems kinda dumb sometimes.
the knife in the shoe was seen on an old television show wild wild west, what's next removable heel for hiding weapon?? but love the going up/down fast on rope but, If I was using it, it would break. the dart drone seems really interesting. keep up the good work
Combining the power ascender with regenerative braking could be a good combination that greatly increases the battery life, a lot of the energy used when ascending could be reclaimed when descending.
@@jonasandersson7367 being powered from something other than a battery would remove a lot of the benefits of regenerative braking and this device in general. Do you really want an engine right next to your face and maybe inside too? Regenerative braking works well with electric drive systems, it works with hybrid too but doesn't quite have the same benefits due to needing both an engine and a motor. The ascender wouldn't need to work any differently to how it currently does, it would just need an esc capable of regenerative braking.
The bullet resistant suit is cool, but I didn't see any indication that the suit has trauma plates. Without trauma plates, being shot while wearing bulletproof clothing can still kill you. Without trauma plates, the trauma from a bullet impact will cause broken bones and damage organs. A shot to the chest, for example, can punch bones into lungs or cause the heart to stop. And, the larger the calibre, the more trauma a person will feel.
I had glasses like that when I was 12 and I'm pretty sure I only paid 5 dollars from some martial arts magazine. I even brought ninja stars and a grappling hook
Rosa Kleb was the original for the shoe blade in From Russia With Love. In the movie she didn't connect with Bond but in the book she did. Next book was You Only Live Twice when Bond is saved
TIHK is amazing!!! I have one on EVERY pair of boots and at the back loop of my UF Pro Shooting Pants. You can get about 2-3 uses out of one key so don’t buy just one! Buy a dozen as you can practice with one and use a bunch and give the rest to friends as you’ll be a hero!
Depends on the cuffs really. Older ones with a chain allowed enough mobility that it wasn't hard at all, but newer ones that are just on a hinge restrict movement and can make it pretty hard to get enough leverage to turn the key once you get it in place.
Those rear view spy glasses have been on sale in many different formats but basically the same product. Even in the back of comic books since the 50s, maybe 60s at latest. These guys have probably only got patents for type of glass used, or some process of manufacture. Definitely NOT for rear view glasses.
Hey, just to let you know, it's not the only company in the world that makes the custom made bullet proof suits. There's one in bogota colombia. The man there has made things for presidents and other high-profile people.
Love that power ascender! The Surin suit might be handy in Portland, Seattle, Chicago, or D.C. The boot knife will get you a nice felony conviction in most US states.

the nylon handcuff key looks like a great idea , and it is considering that you can get it through a metal detector , but it lacks the little nub on the end of handcuff keys . That nub is used to undo a double lock by shifting a bar over in the little slit , if the cuffs were double locked .
@@101perspective nothing about the design said that it could ... but says that it can unlock handcuffs , and it can , so long as they haven't been double locked ... zipties can be brute forced , or the sides of the square clip can be squeezed , or you can jam something flat and narrow inside the griplock and undo it that way . Basically there are a lot of ways to undo zip ties

I wanted to write the exact same. Without stiff plates that spread the impact force you will likely have severe internal damage. Even if the bullet itself does not puncture the skin

2:20 "New, Unique...." Nah, I was born in 1980. In the late 80's, there was a TV show that some guy was walking around with sunglasses that had those mirrors painted on the edges like that. This is not a new thing. It's looks a little better than the ones I remember, but they are not a new concept or product at all.
Yes they do. It's a regular handcuff key, just small and made of polymer. To unlock the double lock you turn the key one way first to unlock the double lock then the other way to release the shackle.
@@echochamber4420 if they're chained cuffs it's not that difficult to turn the cuffs to have keyhole access with opposing hands even if keyhole is facing elbows. If they're hinged cuffs it's much harder to access the keyhole, but still possible for some. Also, chained cuffs can be broken, with lateral force on the chain hinge (swivel that connects to cuff body). I learned how to do it, and have broken the chain off multiple pairs of legit police issue cuffs. It's not easy and you have to learn to bind the chain up and understand the physics. But anyone of moderate strength can break the chain on most standard cuffs once they learn the method. For this reason I won't trust chained cuffs.
I had those glasses as a kid to prevent assassins creeping up behind me. I was lucky to get through my formative years.
