Control sword, switching hands (5)
I believe the answer is:
steer
'control' is the definition.
(I know that steer is a more specific form of the action control)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for steer that I've seen before include "Con" , "Guide the bull" , "give guidance" , "bovine creature" , "Guide, control" .)
