Wood-smoothing tool (5)
I believe the answer is:
plane
This clue is a double definition.
'wood' is the first definition.
(I've seen this before)
'smoothing tool' is the second definition.

(Other definitions for plane that I've seen before include "What imitates bird" , "Form of transport" , "Tool for smoothing wood" , "Woodworking tool" , "barked?" .)
