I have a Fiskars that I have not found anywhere else. It is spring loaded. I found it on vacation at a Walmart, but haven't seen it anywhere around here. So either it is new and great, or I'm behind the parade and still like it!
To cut with it, you have to squeeze the two handles like scissors together. This lets the blade drop down to cut. (there is a lock to keep it open) Then when you release
the handles (unlocked), the blade goes up where it is not exposed. and the handles go apart.
Love it!
I love it. My DGD can't squeeze it enough to get cut.
