Shops saying cut certain with this item (8)
I believe the answer is:
chainsaw
'certain with this item' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'shops saying cut' is the wordplay.
'shops saying' becomes 'chain' (I can't explain this - if you can you should believe this answer much more).
'cut' becomes 'saw' (sawing is a kind of cutting).
'chain'+'saw'='CHAINSAW'
Can you help me to learn more?
(Other definitions for chainsaw that I've seen before include "Power tool" , "Powered cutter" , "Texas massacre tool" , "powered device" , "Timber cutter" .)
