That link is even better, thanks.
IMHO they are like tubular locks, with pin-in-pin, and lateral (not rotary) movement - I don't see why they should be particularly secure, except for that they are seldom and not well explored.
Right, and I think this is a good addition to locks on domestic premises. You can take an EVVA 3KS which is pickproof but not very secure against drilling and snapping and add the Geminy to prevent easy compromising through these kinds of attacks.
No single lock will ever be totally secure against EVERYTHING. If you want security to a certain degree, you don't need a specific product, but a concept. If someone picks your Geminy he will probably fail picking the EVVA 3KS. If someone wants to do destructive entry be snapping/cracking he has to overcome the Geminy first, which looks kinda sturdy. Nothing to snap easily, you will have to drill and make noise etc.
