PFAFF Coverlock Upper Knife | #H004131

The upper knife (part H004131, also referenced as 396001-60 and 10176) is the primary cutting blade in the serger trimming system, working in tandem with the lower knife to slice fabric cleanly at the seam edge during each stitch cycle. Keeping this blade sharp and intact is essential: a worn or nicked upper knife produces ragged, uneven cuts and disrupts the smooth feed of fabric through the looper system. This replacement restores precise, accurate trimming and consistent overlocking performance. Precision-engineered to the original specifications, it slots directly into the knife carrier without modification.
