I Saw some rainbow hex key,like Wiha,PB,and Wera.
It seems both Wiha and PB uses powerder coating,it may be wears off,thet are HEX shaft
Wera uses PVC sleeves,on a round shaft,which looks stronger.
Which one is better,Wiha or Wera?
I have both the WERA Plus and the PB Swiss. However, I don’t use them enough although I have had them for close to 5 years to discover which finish is more durable.
I am sure others will chime in with their experience.
The Wera plus system is the best in my opinion. The hex engagement is amazing and the round shaft design makes for less flex when really putting torque through them. Only down side to the round shaft is on smaller sizes, if the fastener is recessed to far down the round shaft bulk can stop you from reaching. Use my old Bonhus wrenches if this happens.
