Depends on the carve. You're doing a lot more than filing at that point (hopefully), it's more of a re-carve or I guess a shave, but it depends on how deep the V was to start with. 

You might get better help if you give us some more information to work with, maybe full sentences and ideas so you can convey what you have and what your goals are.
