The "Secural" process was introduced by FABER-CASTELL in the 1960s.

• Prevents the lead slipping out of the wooden barrel 
• Enhances the breaking resistance of the lead, e.g. when dropping the pencil
• Facilitates the sharpening of the pencil

In past: The two slats were only spot-glued.

Nowadays: The lead is firmly bonded along its entire

                   length to its wooden casing
