I was shopping at The Container Store last weekend and saw one of these Slice precision cutters. I've had a paper cutter with a ceramic blade before, but this one is such a pretty green that I put it in my cart.
When I got home I took it out of it's package. It feels really good in my hand. It has a soft finish and is weighted well. It cuts paper like a hot knife through warm butter. It does not cut fabric. I may not use it often, but I know I will use it.
Turns out that these folks make ceramic cutters for food too. Check them out here.
FYI – If you have never been to a Container Store and you get a chance to visit one, don't pass it up.
