LNKA Upper and Lower Knife Set for Singer, Pfaff, and Babylock Serger Machines (14CG754, 14SH654, 14SH644, 14SH744, 4762, 4772) Review

The lower blade fit the serger. The upper knife did not fit. When I matched it to the existing blade, it was slightly shorter. As a result, the top blade could not pass through the bottom blade to cut through the fabric.

This item worked well as replacement blades on my Singer ProFinish serger. Good value for money compared to taking the machine to a sewing machine shop and having it done. Just be careful when you take off the old blades, put the new blades on the same ones!

Needed asap and let me down. Changing the blade on the serger is easy - no problem. The blade itself was dull and would not cut through more than two thin layers without damaging the fabric. On the other hand, if it's too thin, it won't cut it either, just eat it up and spoil the fabric again. I ended up just ordering from a local repair shop to make sure I was actually cutting and not wasting time. upset.

I ordered this to replace my Singer 14SH654 serger as it is listed as compatible with these blades. While the bottom knife was fine, the top knife was significantly shorter than my machine's original blade. This creates a gap of approx. 4-5 millimeters between the blades during installation, so nothing is cut. Very disappointed after waiting 2 weeks to finally receive them (the first order I placed got lost in the mail) only to find that they don't work.
