I am running a small business with my husband and we want to make our own post card sized flyers, using cardstock. Since the full sheets are much cheaper than the individual post cards, I am looking for a quality, affordable paper cutter that I can use in my home office to cut the sheets into fours. I need something that is kid safe, but still sharp enough to cut through cardstock. I have found a few on Amazon, but I'm seeing a lot of complaints about the cutting quality. Please lead me in the right direction, if possible!
