A yogurt pot full of industry knowledge

The PB 100 Classic screwdriver has been Liliane Kramer’s reliable companion since her childhood.

«The Classic screwdriver is the perfect, all-purpose lifelong companion.»

A lifelong, loyal companion

Liliane Kramer is a trained businesswoman who studied business economics and grew up surrounded by tools. Her father already passed on industry knowledge to her when she was a child – with the help of a yogurt pot. Every evening, all the items he had in his bag would go into the yogurt pot and then be taken out one by one. The challenge for Liliane Kramer was to correctly identify the screws based on their size and characteristics. It was during this playful learning session that she first encountered the PB 100 Classic screwdriver, which her father always had with him. Since then, it has become an indispensable part of her life, starting from when she was a child and was allowed to go with her father – with her own toolbox – as he repaired door cylinders and locking systems. 

Even today, when Liliane Kramer fills in for a colleague on vacation, the PB 100 is always by her side. With its universal usability, durability, and space-saving design, it remains her number one choice.
