I don't know what mine are called, but my LQS gave them to me when I bought my embroidery machine. They're tweezer type with a small very sharp curved blade at the end. They are fantastic! You can lay the edge of one blade under and up against the edge of the applique and when you have it - snip. I usually fold my applique against the edge a bit to help. But yes ... be careful!!
I'll try to take a picture of them tonight when I get home from work.
