This Baby Lock lower serger blade fits these Baby Lock serger models: BLE1 Eclipse, BLE1AT Imagine, BLE1DX Eclipse DX, BLE1DX-2 Eclipse DX, BLE1LX Eclipse LX, BLE1SX Eclipse SX, BLE8 Evolve, BLE8W Evolve, BLE8W-2 Evolution, BLES8 Ovation. A sharp lower and upper blade will keep your serger sewing its best. When the blade is sharp you will get a smooth cut on the fabric and the serger will feed the material through smoothly. When you serger blades get dull then the fabric does not feed through smoothly causing your stitches to wad up and the serger to jam.
