Ledge too awkward for a cutting instrument (4,4)
I believe the answer is:
edge tool
'a cutting instrument' 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?
'ledge too awkward' is the wordplay.
'awkward' indicates anagramming the letters.
'ledge'+'too'='ledgetoo'
'ledgetoo' is an anagram of 'EDGE TOOL'.
'for' is the link.
Can you help me to learn more?
(Other definitions for edge tool that I've seen before include "Knife or axe, for example" , "Maybe saw" , "Chisel or knife, say" , "Implement with one or more cutting sides" .)
