Is the lock actually failing? Can you close th blade without touching the lockbar? Is this knife new? Many liner/frame locks only have about a 10% lockup when new to allow for break in. As the lockbar wears it will engage further over across the tang.
If the blade feels secure, then I say do not file the edge of the lockbar, there is some specific geometry in the relationship between blade and lockbar. Give the knife a thorough cleaning, possibly some debris may be preventing the lockbar from engaging entirely.
Got any pics?
