Peeling knife (5)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
parer
'peeling knife' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for parer that I've seen before include "Trimmer" , "One shaving away edges" , "It's used to sharpen a pencil" , "one prunes" , "Knife for vegetables" .)
