Sewing Machine Needles

[Kustom]

How do you know when it's time to replace the needle on a sewing machine? Should they be stropped with rouge?

Thanks, Steve

If I remember what my information from Artisan said...the needle should be changed out after 10 hours of sewing. The issue is not in the sharpness of the needle but the way the steels temper changes from the friction.
