Bondhus Hex keys use a modified hex design as well, that grips better than older regular hex.
The bkack finish on the Bondhus hex keys is excellent at preventing rust, since I've gotten Bondhus keys wet, and just left them wet in a tool box, and they dried with no rust.
Bondhus is also US made, and relatively affordable.
Can you direct me to more information about Bondhus having a modified hex design?
