Gemini shield

[jos weyers]

question:

I opened the Gemini shield in the dutch Toool competition suitcase.
Should something like that be discussed in the advanced section? (to which I don't have access)

Hello from the past, (I always giggle when I see future timestamps on forums due to different time zones)

Although I am a very new (forum member) here I would assume that that lock would be restricted to the advanced section (of which I am not apart of yet).

I wish I could play around with the "egg" and the gemini locks though. They look like a lot of fun to pick.

The mechanism and nature of the lock does seem like material destined for the "Advanced" forums, seeing how it is generally used to guard high-value and high-risk assets. This is the first instance I've ever heard of someone making this accomplishment (though I'm admittedly not on the Advanced forums either), but from what I hear, it's a hell of a feat! For what it's worth from a beginner, great job!

Jos,

I never heard of that lock before (shame on me?), do you have more info about it?
Opening the lock might be advanced material, but simply discussing the features of the lock isn't as far as I know

It's a 5 pin-in-pin design with all pins accessible from the front (there are also 7 pin-in-pin versions).
They do offer very good protection against vandalism.

The amount of protection against manipulation of a lock that has all pins exposed at the front - well, judge for yourself.

Cheers

P.S.: There are also versions with an additional electronic locking system, used on train ticket machines.

Let me offer up a quote from Neal Stephensons Cryptonomicon.

......have taken to going around conspicuously armed as a way of pointing out the absurdity of those rules. Their point is this: who gives a shit about concealed weapons anyway, since they are only useful for defending oneself against assaults by petty criminals, which almost never happens? The real reason the Constitution provides for the right to bear arms is defending oneself against oppressive governments, and when it comes to that, your handgun is close to useless. So (according to these guys) if you are going to assert your right to keep and bear arms you should do it openly, by packing something really big.

Concealing your mechanism from manipulation is a good thing, but its rendered moot if it is near impossible to manipulate the mechanism in a way that opens the lock.

Not that this lock is perfect, and the fact that it has been picked is good proof.

Its just that this lock likes to go around "conspicuously armed" with a 4 shot derringer loaded with blanks...............................

So in circular logic, your right

Just posting what went through my head when I read that.

I really like the idea behind it. Layered security is a very important concept. It's also more than saying "Now you have to pick two locks" - it's "I take my security seriously." I kinda like the magnetic ones more. They are easier to unlock from what I've seen, but probably less susceptible to vandalism such as super glue.

[l0ckp1cker]

Where can I find one of these locks?
Is Gemini the brand name?

[w00tb0t]

The brand name is Drumm Security,

You can get them at the host site, http://www.drummsecurity.com/g.php

Or if you are stateside you can get them quicker here https://securitysnobs.com/Drumm-Security/

the mechanical ones work VERY good against superglue.
(if properly maintained, ie. lubed one a year)
more info on the lock can be found in Han's article op the dutch toool website:

Too bad they are so expensive, they look like a really nice challenge to pick, especially with those special mushroom pins in there...

actually, the mushrooms don't make it any harder. The outer pins can be decoded quite easy and that's the only spot that has mushrooms. Ones you have the outer pins set, you are left with a "normalÎ… 5 pin lock
