New, replacement L-Pin for the vintage Singer Pinking Attachment. Notice the L-Shaped Pin in the photo on the vintage original Singer Pinking Attachment? It has a simple but useful purpose. In order to remove or replace the cutting wheel on the Pinker, the attachment gears need to be disengaged. Inserting the little pin into the gear hole will prevent the gears from turning, making it easier to clean excess lint behind the cutting wheel or replace it with a different trimmer style altogether!
