BDK tool committee

- Tobias Gaiser |


This time, we're diving into the process of restringing, showcasing an innovative, precise system that offers an intriguing alternative to the traditional marking method. 

Drilling hammer heads is also on the agenda, along with a selection of handy tools. 

In the realm of tuning hammers, we're presenting not only DIY solutions but also a new, ergonomic carbon variant. 

I've always been thrilled by the presentation of fresh, spontaneous ideas. It would be great to have you join us.
