For its companion, take your pick! (6)
I believe the answer is:
shovel
'pick' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for shovel that I've seen before include "Tool for moving, earth say" , "Tool for scooping" , "Digging implement" , "Tool for moving, eg, coal" , "''Don't forget your..., if you want to go to work'' (Christy Moore)" .)
