One engaged in sharp trade practice? (6)
I believe the answer is:
cutler
'one engaged in sharp trade practice?' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
This is the entire clue.
Can you help me to learn more?
(Other definitions for cutler that I've seen before include "Sheffield craftsman maybe" , "Knife etc. maker" , "Maker or dealer in knives, forks etc" , "Knife-maker" , "Maker and seller of knives, forks and spoons" .)
