Sharp?
Maybe I got a box of duds, or something, because my pen blades are definitely not sharp. I think my scorer goes deeper than these do. It looks like a razor blade, but it sure doesn’t cut like one. I was trying to go through cardstock and I would have to go over the cutting area again and again before it came loose. I also made the mistake of buying the big box because of the great reviews on here and it seemed a better deal. I am not happy that I threw away $26 and then get on line and find out I can get medical disposable scalpels for less than $10 for a box of ten. I usually shop around before I hit the buy button and I sure wish I had this time.
