Unpickable? That is up for debate, but this very clever design is sure to confuse most people who would try to pick it!
Even with knowledge of its workings the I do believe this would be a tricky beast to manipulate.

![[47] 7 pistol keys Padlock (Picked- on location!)](https://i.ytimg.com/vi/4ss5bhOq7Io/mqdefault.jpg "[47] 7 pistol keys Padlock (Picked- on location!)
Heres another interesting padlock from the 007 series of padlocks. You can see these also continue the theme of pistol shaped keys, but these are particularly big and are in a circular dimple key design.
There are pins on the top and bottom of the keyway. The top of the keyway has a Tensioning bar at the very front that almost looks like a pin. This bar slides thorough a channel cut down the length of the key.
Not high security, but still highly interesting (at least for me)!

The Forever Lock is now more secure than ever!
We were finally able to get the Forever Lock upgraded to a new Key and new core. The new core uses a 5 slider system with no springs.
This was done to address concerns about bumping and key impressioning which both take advantage of spring pressure on pins.

![[16] Saint Fire Corkscrew Key Lock!](https://i.ytimg.com/vi/5ZXO7fyVhsA/mqdefault.jpg "[16] Saint Fire Corkscrew Key Lock!
Heres an awesome and very unique Lock I found recently.
It has a corkscrew key that threads into the keyway and interacts with 4-pins. I love the design~ the keys look and feel so great!
Not sure of the age, but it is definitely not in production anymore.
Love finding locks like this!")
![[28] VELO- Dual Core Padlock [Demo + Picking]](https://i.ytimg.com/vi/5eaSd8F3usQ/mqdefault.jpg "[28] VELO- Dual Core Padlock [Demo + Picking]
Heres a really neat vintage lock from 1979 that has two locking cylinders that each require their own specific key.
Both keys have to be inserted and the cores must be rotated simultaneously, so the owners of both keys must be present to operate the lock.
As you can see it looks very similar to a Vachette padlock body and has a similar style locking bar.

Want to get medieval on Potential thieves!? These ultra massive U-Locks are no joke! When it comes to sheer size and mass, I dont think any other U-Lock can compare to these bad boys!
With a XXXL large 40mm Shackle and weighing 5 pounds for the small and 9 pounds for the large, these Locks are sure to make a potential bike thiefs eyes bug out of their head.
These come with 2 extra Long Inner groove keys and would definitely require someone to get creative to pick them.
Why Lock your bike to a Bike rack when you can lock your bike WITH a bike Rack! =P

![[53] Chinese Magnetic Power Box Lock (Bypassed/Picked!)](https://i.ytimg.com/vi/8ZNUgsplYk4/mqdefault.jpg "[53] Chinese Magnetic Power Box Lock (Bypassed/Picked!)
Here is an odd little lock from china that is supposedly used to lock up power or utility boxes to help prevent tampering. It uses a magnetic key and has no pins.
I didnt have a strong magnet it try and open the lock, but I did have my trusty screwdriver!
Not a very secure design, but still something new for the collection!

Here I Demo a Forever Lock concept for a Door. I know a lot of you said you thought the design would also work well for doors so I pulled a few strings and got this to show you! I hope you find it interesting!
Please let me know if any of you are interested in purchasing a door lock like this. They are not currently in mass production, but if there is enough demand I could possibly order a custom production run to get them made for you guys.
I also show 2 other door locks I have that I consider to be unpickable, simply because I have never heard of anyone picking them. I would say the chances of a random thief picking these locks if they were on your door is almost zero.")
