I keep buying different hex hey sets looking for one that really works. Cheap stuff breaks and rounds off- if it even fits right to begin with. I've got Bondhus, Klein, Eklind, and even snap-on and Excelite hex drivers, but I keep searching.
I was ready to bite on a Wiha set, but I don't like Wiha's handles. I really prefer a regular key, especially if it is long and balled on one end.
The Japanese are proud of their steelmaking, and consider tools to be instruments. I am excited, it's been a long search.
