Sharpening a serger blade? Sewing Machines Parts and Sales in Los Angeles

I’ve been using my serger on a lot of things lately (mass producing quilted stockings, and cotton pajama pants mostly). A couple times fabric has like, “gotten past” the blade of my serger, and caused the serger to siege up one of the needles to break.

I’m not sure if the blade is dull or if I’m doing something else wrong. Is there a way to get the blade sharpened on a serger? If it’s not that, does anyone have an idea of what it could be?
