One upper and one lower knife cutting blade for the White Superlock 2000ATS, 2500D, 2900D, 1934D Sergers by Jaguar, plus clones from Singer, Viking, Reliable, Yamata, Gemsy, etc. Worn knives should both be changed at the same time. Never put a new knife blade against an old worn knife blade.

I was so happy to find a complete set of cutters for my White Serger. It is getting more difficult to find some parts as it is getting older. However I use it constantly and it is my favorite serger. I was delighted to find your site and will recommend it to others. In fact, I recommended it to a dear friend and seamstress last night. Thank you for your fast shipping and fair prices.
