If you mean the scissors, I use them when unpicking. The point at the end of the cutaway part slips under the stitch, then you just cut like an ordinary scissors. I find them much safer than a quick-unpick - less chance of them slipping and cutting the fabric. I first bought them years ago when I did cross stitch.Working with 2 strands over 28 count linen, they were better for removing stitches without cutting the *expensive* linen. Cost about $A14.
