Most of the tiny threads from the front pull off when either ripping or when the back thread (the bobbin thread) is pulled off. It is quick, and no sharp blade used. I don't trust myself to not cut myself or the fabric. I used to use a sharp blade or my serger seam ripper and spread the fabric seam apart and cut the threads, but stopped because I didn't like the feel of the blade it in my fingers. Now I just grab under those stitches and snip them clean with my little ripper.
