What one made sure was sharp? (3)
I believe the answer is:
saw
'sharp?' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'what one made sure was' is the wordplay.
'was' can be anagrammed to 'SAW'.
However, I'm unsure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for saw that I've seen before include "Observed the old saying?" , "Cutting tool - did 23" , "Viewed; adage" , "Was turned into a cutting tool" , "Implement for cutting wood" .)
