SINGER Overlocker Lower Blade Knife
The knife has a hole in the middle for fitting.
We always recommend you change your overklock knife blades as a set to prevent a newer blade being worn or damaged from cutting against an older worn blade.
Singer make a few different types of blades so make sure you order the correct ones.
