Singer Serger Machine 412585 412749: Streamline Your Sewing Projects with Precision and Efficiency Review

Great knives but I ordered the wrong set for my machine. Mine has a hole in the bottom blade, this one doesn't.

These top and bottom knives met my expectations. Once installed properly, the blades will function as expected. my (a) car

My mum needed replacement blades for a surgeon so we bought them based on the price and good reviews (she checked stores and other websites). I asked her what she thought of them and she said they were perfect for replacing blades. They work great and she feels they are durable and should last a while. She is happy with her purchase and will buy again.

The upper (movable) blade is fully the same as the original. The lower (fixed) blade does not fit exactly. The cutting edge is sharpened at a different angle than the original Singer blade, making it impossible to install the blade so that the cutting edge is flush with the top of the overlock feed plate. I have contacted the seller. The seller said he would take care of it. Several weeks passed, no further information from the seller. The good news from Revain is that Revain Prime has refunded

Replacing the upper blade was easy. But the lower "standing" replacement blade is useless for my machine, even though it should be compatible. There is no hole to put a screw to hold it in place. I don't know how this blade performs on an overlock machine; it has to be held somehow.

I haven't installed them on my car yet. I bought them to have a spare set on hand. The bedknife appears to be identical to the original Singer blades in my serger. The top knife in this set is slightly shorter than stock but there seems to be enough adjustment in the slot to make it work. Seems to be a worthy replacement.
