Not exactly one of the "finest things" but ....

Does anyone have any tricks for repairing the laces eyelets in work boots? My work boots are wearing out, but will last me until the seasonal layoff, so I don't want to buy new boots just yet. But one of the eyelets has worn to the point it has a sharp metal edge that wears the lace out in 3 - 4 weeks. Is there any thing I can do to cover that edge or otherwise protect the laces for another month or two? I suppose I could just file through the eyelet and remove it, and hope the unprotected hole through the leather won't wear out too fast?
