This will cut timber from the far west (7)
I believe the answer is:
fretsaw
'this will cut timber' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'from the far west' is the wordplay.
'from' indicates anagramming the letters (from the letters).
'far'+'west'='farwest'
'farwest' is an anagram of 'FRETSAW'.
Can you help me to learn more?
(Other definitions for fretsaw that I've seen before include "Fine-toothed tool" , "Woodworking tool" , "Tool for cutting designs in wood" , "cutter" , "Woodcutter" .)
