Q: I have mostly Bernina sewing machines, and have often read on the Bernina yahoo groups that one should not use your titanium coated topstitch needles because they are longer or somehow different than Bernina, Schmetz, or plain Organ needles. Sometimes it is said that it's safe to use them for embroidery or straight-stitching only, but not zig-zag or decorative stitching. I would sincerely appreciate a definitive answer. I don't want to damage my beloved and expensive machines, but I also don't want a myth to prevent me from using my favorite needles.
A: Regarding our titanium-coated Topstitch needles and Schmetz's titanium Embroidery needles: Schmetz titanium Embroidery needles are slightly longer than our titanium-coated Topstitch needles (made by Organ Needle Co.). Below, you will find a picture of a #100/16 Schmetz & our Superior titanium-coated Topstitch needle, also #100/16, side by side.
The Schmetz Topstitch needle is .03 mm or .001 inches longer than our Superior titanium-coated Topstitch needle. (The benefit of the Topstitch style needle is the deeper groove along the shaft, this will allow the thread to lay into the needle and avoid more friction caused when stitching.)
We have over 25+ Bernina 730's in our facility and we only use our brand (Made for us specifically by Organ) of needles in them and enjoy great sewing success. I hope this helps to answer your question.
