Han just received some locks from GeGe. It is nice to see people keep their promises…
This is what Han has to say about them:
The locks in the picture are some locks we got from Gege, from the left to the right: P-extra, AP2000, AP3000, ANS-2 and the AP4000.
They all have an exotic looking keyway, but besides that here is a lot to tell about the inner live of these cilinders, they contain for example horizontal sliders, undercuts, cogwheel, special anti-bump pins, key copy protection, spring loaded axial pins, carbide sintered steel insert, etc.
I intend to write an article about these high security locks, so that you will learn more about these cilinders.
