I enjoy just wearing a pendant around my neck on a cord. It is so much easier to use it to cut threads than looking for scissors that I‘ve dropped or misplaced. I send or give them to my friends who sew.
This pendant is a great option for traveling when carrying scissors is less than ideal. The blade is not as sharp as a good pair of snips, so you won't get a super clean cut, but the convenience of it makes up for that fact.
