Carbide Lower Knife 787035004 for Serger Overlock Machines

787035004 is a carbide lower knife for serger (overlock) machines. The lower knife sits below the stitch area and works against the moving upper knife like a pair of scissors, trimming the seam allowance just before the loopers wrap it.

Carbide holds an edge far longer than plain steel. If your trimmed edges come out frayed or chewed, or the knives push fabric instead of cutting it, a worn lower blade is a common cause. You receive one lower knife.

Serger knives are model specific, so look up 787035004 in your serger's parts list before ordering. When fitting, bring the blade up level with the needle plate and check that the upper knife overlaps it slightly at the bottom of its stroke.
