An oar for a cutter (5)

I believe the answer is:

blade

This clue is a double definition.

'an oar' is the first definition.
(I've seen this in another clue)

'for a cutter' is the second definition.
(I've seen this in another clue)

(Other definitions for blade that I've seen before include "Sword" , "Cutting edge" , "See 24 Across" , "A knife, or a dashing fellow" , "London rail terminus" .)

I've seen this clue in The Globe and Mail.
