main axis of object

i rotated an object at a certain angle see pic blue object
but when i select global or local the axis ar not as per the main axis of the object

is there a way to change axis to fit the main axis of the object?


In your image all the manipulators are set to global.

i tried global normal local and i could not scale as per main axis of the object
i wa wondering if there wa a way to get back thes original axis after doing several rotation ob the object !

Scaling a angle compared to the main axi of the objet does not give the best results!
