I don't know what's wrong with the cutter. Everything looks normal to me. I did hear a snapping sound, and after that it didn't work. I tried new blades, so it wasn't a problem with the blade. And I cleaned it, so that isn't the problem, either. Previously when a cutter stopped working, they said it was because I was pressing too hard and ruined the bolt, so maybe it's that again. That time I sent them the cutter; this time I sent an email asking about replacement parts.
