Battered relics found in the kitchen (6)
'the kitchen' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'battered relics' is the wordplay.
'battered' indicates anagramming the letters.
'relics' is an anagram of 'SLICER'.
'found in' acts as a link.
Can you help me to learn more?
(Other definitions for slicer that I've seen before include "Machine for cutting, eg, ham", "Kitchen utensil", "One making ball curve", "Cutting implement", "Device for, eg, cutting eggs".)
