Question posted by southernbowcoinfo on August 28th, 2022

Does Anyone Know The Part Number For Replacement Knife & Blade?

I am having the hardest time finding replacement blades and knives for the ST4031HD machine. I can find them all day for literally every other serger/overlocker, just not for this specific model. Will another model's knife/blade set work on the ST4031HD?

I Know the Answer!
