Babylock upper knife for a range of Babylock overlockers.

Part code B4401-04A-OY

Over time the effectiveness of the upper knives on any overlocker can become compromised, resulting in difficulty cutting fabric or fabric bunching under the foot without giving a clean cut. Give your machine a new lease of life with a new upper knife.

You can check the model number of your machine in one of three ways - the front cover of the manual, a sticker either on the bottom or rear of your machine or on the product packaging. Make sure your model number matches exactly. Compatible with the following Baby Lock machines:-

  • Baby Lock Acclaim (BLE S4)
  • Baby Lock Victory (BLE S3)
  • Baby Lock Enspire (BLE 1EX)
  • Baby Lock Enlighten (BLE 3ATW-2)
  • Baby Lock Imagine Wave (BLE 3ATW)
  • Baby Lock Imagine (BLE 1AT-2)
  • BLE 1DX-3
