blade

'sheffield?' is the definition.
Both the answer and definition are singular nouns.
Maybe they are linked in a way I don't understand?

'dashing young chap from' is the wordplay.
'dashing' becomes 'b' (I can't explain this - if you can you should believe this answer much more).
'young chap' becomes 'lad' (I've seen this before).
'from' becomes 'e' (I've seen this in other clues).
'b'+'lad'+'e'='BLADE'
