Let’s Learn About Needles – Anatomy

Posted on

Last week I talked about the new Chrome sewing needles by Schmetz and why I love them so much.  I decided I want to know more about needles and how they work, so for the next few Saturday’s I plan on learning about sewing needles and want to share that knowledge with you, courtesy of Schmetz!

Just like people, needles have an anatomy.  If you know the parts of the needle, it will help you to understand the different types of needles better.

Butt: The beveled end allows easy insertion in the needle bar.
Shank: Household needles have a flat shank, while commercial and industrial needles have round, threaded, notched or other special shanks. Shanks allow perfect positioning of the needle in the sewing machine.
Shoulder: The sloping area transitioning between the shank and blade. SCHMETZ color codes appear on the shoulder.
Blade: Needle size is determined by the blade diameter (i.e., size 75 is .75mm).
Groove: The groove cradles and guides thread to the eye. The length and size of the groove vary according to needle type.
Scarf: The indentation above the eye that allows the bobbin hook to smoothly grab the thread under the throat plate to create a stitch. The shape and size of the scarf vary according to needle type.
Eye: The hole through which thread passes. The shape and size of the eye vary according to needle type.
Point & Tip: Length, shape and size vary according to needle types.

In addition to these parts of the needle, Schmetz adds two color bands to identify the needle type and needle size.  Next week I will talk about the different types of needles, what you would use them for, and the Schmetz color coding system.

Would you like to save and carry any of this information about needles?  Schmetz has their own app!  It has all of the information we have shared here plus more.  Download it from the Apple App Store or Google Play.
