Magic Key Саm/Border4+4
Self-impressioning lock pick - magic key for such types of locks as CAM, Border 4+4.
Keep the tool with extended pins in the opposite direction - it is obligatory.
Before the work may need to drive pins into both sides 2-3 times.
In very rare cases, and only for certain locks may need dry lubrication, but again, in very rare cases, usually just enough to drive pins.
