Query: guillotine paper cutter

I purchased this paper cutter to cut down on our kids' project time. First and most importantly, the blade is very sharp and when not clipped into place, demands your full attention when lifting the entire trimmer. My youngest attempted to trim paper with my guidance but the paper crumpled instead of cut. When I have used it, I have had no difficulty. It is weighted well and is precise.I would recommend to all.
