Hard container for one chopping wood? (5)
I believe the answer is:
Here is my best explanation:
'one chopping wood?' is the definition.
'hard container' is the subsidiary indication.
'hard' becomes 'h'.
'container' becomes 'ewer' (ewer is a kind of container).
'for' is the link.
(Other definitions for hewer that I've seen before include "Person cutting (wood, say) with blows", "Axeman", "Nick" and "cutter".)
