Neat and safe seam ripper
I purchased this and unfortunately had the opportunity to try it out! You definitely need to purchase the pointed blades to go along with this, as the tip that comes with it is blunt so that you cannot use it to get underneath the thread. I was able to use it with the blunt blade once I got a few threads loose. So far, so good! But I will be putting in the pointed tip blades for future use.
