I believe the answer is:
saw
This clue is a double definition.
'eyed' is the first definition.
(I've seen this in another clue)
'cutting tool' is the second definition.
(I've seen this in another clue)
(Other definitions for saw that I've seen before include "Grasped" , "Was turned into a cutting tool" , "Witnessed" , "See 23" , "Toothed blade" .)
