Serger Lower Knife X76728-001, Brother PL1500 & PL2000, Husqvarna Viking 1001L

X76728-001 is the lower knife from a group of Brother and Husqvarna Viking sergers. A serger trims the seam allowance just ahead of the loopers using two knives that meet like scissor blades; this is the bottom one of the pair. When it is chipped or dull, the cut edge comes out ragged, threads snag, and the stitch wraps an untidy edge.

Machines it fits include the Brother PL1500, PL1600 and PL2000 and the Husqvarna Viking 650, 660CD, 1000L, 1001L and 1002LCD. You receive one lower knife.
