The square shrouded models have serrated spools on top and serrated pins on bottom. Once you get the hang of the though you wont have any trouble opening them as the tolerances are poor.
For the best book out there on high security locks and their operation, take a look at amazon.com for High-Security Mechanical Locks An Encyclopedic Reference. Written by our very own site member Greyman! A true 5 Star read!!

You posted in another thread someone else started that you were interested in seeing the answers how to pick this lock because you had one too. viewtopic.php?t=19408 Why start another thread when the questions were answered there?
As Zeek Said, plus, these locks are easier than the american locks they somewhat imitate, because they don't have the anti-tensor spring. (relocking)
Light tension, sensitive feedback from the spools and serrations, and if necessary, a drop of oil, and definatly sand your pix, or you will be feeling the roughness of the tool, and wearing out the lock. USe a wide blade tensor, such as you can make from a pocket clip off a pen cap.
