I bought my first Wiha set from MA in florida (heli tool set) 26 years ago, I have only changed the 1.5mm allen driver...
I started dealing with Wiha when I started Motors & Rotors 20 years ago, sold a lot of their stuff over the years...really pis*sdI chose there range, repeat business is tiny :-)
I have around 100 tools in my workshop (multiples of most so I can always find them!) 1/16th allen driver 2631/16 is great for dealing with rounded M3 set screws!
Favourite set is tool roll in my flight boxes...269T11
