Shop Replacement Serger Blades at WAWAK Sewing Supplies.

Never have a dull moment with your serger: pick up a sharp replacement blade from WAWAK Sewing Supplies! Changing the knives on a serger or overlock machine is important to keep it running in top condition. Serger Knives trim the fabric as you sew for a professionally finished edge. Over time and with use, Serger Knives can wear down and become dull. You’ll know a serger blade needs to be replaced when your fabric isn’t cutting as cleanly—if the fabric is fraying, for example—or if you find nicks or imperfections on the blade after visually inspecting it. To find a replacement blade that will work for your serging machine, enter the manufacturer and model number of your serger machine into the “Filter by Manufacturer” fields on the left side of the page. This will show you only the serger knives that fit your exact machine. WAWAK carries upper and lower knives, chain cutters, moving blades, counter knives, overlock thread trimmers, and more. Shop Serger Knives on this page to find the perfect replacement for your serger blades.
