Kitchen item: pin fixes this roughly (4-5)

'kitchen item' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I don't see?

'pin fixes this roughly' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'this' is 'isht' which is present in the answer.
'pin' could be 'dowel' (peg for fixing together components of a structure) and 'dowel' is found within the leftover letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
