I have an older machine- much older. It's Simplicity brand and I've had it for about 25 years, and it was my mother-in-laws before I got it. I give it a work out and regular maintenance. It came with replacement blades, 2 sets, and I've used them. I was pretty skeptical that these were going to fit and work as well as the blades the machine came with, but I was wrong. They installed easily, maybe 10 minutes total, most of the time nudging the bottom blade up to it's position (Pro-tip, take a close up pf your bottom blade BEFORE you uninstall it so you know if it was set flush or just above flush. Take a video of your blades running so you know how much they close overr each other. To much and your work will bunch up, to little and it won't cut correctly.) Then I grabbed some scrap denim (the heavy stuff) and gave it a go. Like cutting through butter. I'm so glad I took the chance, I've been doing French seams on everything, which is wonderful, but is also time consuming and often really unnecessary. TL:DR Great blades, installed easily and came with bonus machine needles! Review: Sew Kitten is Sew Kool! - Very nice serger knife set for Singer machine. I was pleased to find a Sew Kitten trading card enclosed with my order! How cute! This seller caught my attention and I searched for other products they have listed (of course to get more kitty trading cards, lol). I searched online for diy instructions for my particular serger, but couldn't find any. I settled for a few videos that discuss other similar machines on how to install the knife set. I also consulted my machine manual and enlisted my husband to help. It was successful, but then my machine started having other problems, no of which are related to the knife set. Looks like I'm shopping for a new machine, but my old serger has served me well for the past 12 years or so. If your Singer serger has a dulled knife blade, please consider this product offered by Sew Kitten (for the kitty trading cards, of course!!). ## Features - Brand New Upper and Lower Carbide Steel Blade Knifes (2 piece set) - SERGER MAINTAINANCE PACK - Durable, Accurate Angle Blades Ensure smooth sewing and professional cuts - Singer 14SH644 , 14U part# 412585 and 412749 - Includes lint brush and needles.

Curious freebie *by B***S on August 30, 2017* The part is priced nicely and fit perfectly. It came quickly and everything was dandy. I just don't understand why you would send a "free pack of Serger needles" that don't fit the machine that the knives go to.
