The Fichet F3D High Security Lock Mechanism – An Inside View - Michael Huebler

The Fichet F3D High Security Lock Mechanism is a paper about a very interesting French lock with huge 3D-milled keys. The paper was first presented at LockCon #04 (October 2011, Sneek, NL).

The New Master Lock Combination Padlock v2.0 - Michael Huebler

The New Master Lock Combination Padlock V2.0 is a detailed technical analysis about a new and unique combination padlock from Master Lock, named "1500iDCOL ONE" in Europe and "1500iD Speed Dial" in the USA. And a visualizer application (File:MhVisualizer V2.0 p.swf) that will help you to understand the lock's mechanism even better. Both files have been updated for HAR2009 with some major enhancements and corrections. The topic is also being discussed on BlackBag and in a podcast.

Cutaway locks - Han Fey

One of the reasons why manufacturers produce so-called 'cutaway locks' is to show potential buyers and entry level locksmiths the inner workings of a lock and to show the security features. Some of the cutaways in my collection are factory cut, while some I made myself because I could not get a factory cutaway or because factory cutaways were never made available. The first part of this series is called Cutaway locks and deals with locks by various manufacturers. The second part deals exclusively with Pfaffenhain Cutaway Cylinders.

The Drumm Geminy shield - Han Fey

About 15 years ago Klaus Drumm had the idea that the small surface in front of a cylinder was not big enough to provide for an effective Shield against differing modern burglar attacks. He wanted a solution for this. With this idea in mind, he came to the conclusion that a cylinder shield out of steel which could withstand several attacks could be the solution.

DOM ix Dimple key system - Han Fey

I have examined the locking systems of most European manufacturers including Kaba, ASSA, BKS, Wilka, Winkhaus, Mul-T-lock, etc. It has been interesting for me to witness the progression in these manufacturers evolving security features. I decided to write about the history of the German DOM ix system because this manufacturer came with one of the first reversible dimple key systems with a horizontal keyway.
