Knives

The serger sewing machines' blades may trim the cloth even before the stitches are produced! They contribute significantly to the clean, completed appearance of your edges.

A serger type of sewing machine is capable of binding fabric using an overlock stitch. A single overlock stitch is created by combining many stitches. Knives are positioned in the section of a serger where the material is cut as it travels through the needle. This enables the knives to align with the overcast stitch, resulting in a perfectly enclosed edge. Take any clothing and look for the finishing stitching.
