With regards to the post on a cylinder multi tool which is now locked the orginal poster stated he had done a short course and wanted to know how this tool is used well it must have been short if this was not demostrated and I would love to know what was covered.
The tool in question is used for measuring euro cylinders and for checking the operation of multipoint locking operations as the tool duplicates the cam of a euro cylinder.
When drilling is used to gain entry to this type of lock the tool plays no part in the opening operation however is does if another well know destructive method is used .
This should now be a little bit clearer.
