I want to make a comparison of euro cylinder models that are commonly used here in Germany. To get a fair view I use only new/unused locks to explore their properties - mainly focused on picking. Here you see a lock from ZI IKON:
- key pins all std
- drivers: #1, #5: std, #2, #3, #4: spools
- open keyway
- antil-drill steel pins
1889 Carl-Zeiss-Foundation (by Ernst Abbe) - Microscops
1926 ZEISS IKON AG (more optical products)
1928 Euro cylinders production based on a patent from Sylvester Wöhrle (1924)
1989 Split of Zeiss Ikon - ZEISS (optical), IKON (locks); owned by ASSA ABLOY (1994)
