This lock is quite big, weighing in at about £4.4 it features an absurdly think 18 millimeters sliding bolt Shackle.

As I said, this is a dual custody padlock, meaning that it takes two different keys, presumably held by two separate people to operate the lock.

Essentially, it is the physical embodiment of the so called to man rule, which is common in militaries and sensitive facilities.

But the concept was far more widespread in the industry of the Soviet Union, and that's because of the well developed black market for ordinary consumer goods.

As such, a dual custody lock like this was employed to keep all sorts of products from disappearing into the black market.

The two keys for the lock are made of steel and are extraordinarily crude by modern standards.

Then they're stamped with the numbers.

One and two thes correspond with the markings on the bottom one and two.

So let's put these into the appropriate course and rotate them counterclockwise, which is uncommon on American locks but common on old Soviet locks.

After we do that, the shackle can be removed so on to picking.

Now, when this was new, this would have been a fairly easy lock to pick.

But it's not new.

Everything on this lock is made out of either steel or iron, even the course and the pins.

And with age, everything has rusted.

That makes the pins hard to move, and everything feels pretty crunchy inside.

So it presents some pretty interesting challenges.

All that said, let's get to work picking okay to rotate thes counterclockwise and we'll start with the core labeled number one.

And I'm just using a standard hook.

Nothing on one too.

Three.

Ford is binding.

Gotta click out of four and five.

Gotta click out of five.

Back to the beginning.

One three is But I'm sorry too, is binding.

Gotta click there now.

Three is binding.

Gotta click there.

Nothing on four or five.

Nothing on one another.

Click out of two.

Nothing on 34 or five.

12 three for, uh, click out of five thing on one to his binding.

Here we go.

Click at a two nothing on three.

Little click on four.

Nothing on five.

We're getting lots of clicks out of each pin, which probably means that they have rounded ends on the pins.

Okay, we got number one open.

Let's move on to number two.

The best way to deal with rounded ends on the pins is really heavy tension, but I can't do that right now because really heavy tension with all of this rust would seize all of those pins up.

Nothing on one, too.

34 Okay, five is binding tightly.

Gotta click out of five, but it's still binding.

There we go.

Another click out of him.

He feels set.

12 three is binding.

Click out of three Little click on four.

Nothing on five.

One, two, three.

Okay for another click out of four.

Nothing on five.

One, two three.

Another click out of four.

Nothing on five.

Little click out of one two is binding tightly.

There we go.

Click at a two.

Nothing on three for his binding quick out of four.

Nothing on five.

Click out of one.

Nothing on 23 Another click out of four.

Nothing on five.

Not sure what's holding us up now.

Here we go, little click out of three, and finally we open this up.

So that took quite a while, considering that each of the cores have only five pins, but they are standard pins that are very, very rusty.

So it's not the locket is the rusty internals that make this so tricky a lock to pick.

Either way, I think it's an interesting old lock.

That's all I have for you today.
