Dual Part Compatibility: Directly replaces both part numbers #42305 and #138559, ensuring a wide range of model compatibility.
Industrial Durability: Crafted from high-impact hardened steel to resist chipping and maintain a razor-sharp edge over extended use.
Clean Edge Results: Engineered to provide a smooth, "shear-like" cut that eliminates frayed edges and prepares the fabric perfectly for the overlock stitch.
