You know, now that I think of it, there are ceramic cutters out there (thank-you, Amazon). They're much safer than metal blades, and can cut through thin media. I don't think they cut as clean as metal blades, but it's an option, right? Has anyone used a ceramic blade? I think I'll order one (which one?) from Amazon, or try to find one in a store. That will be a nice thing to review during testing.
Thanks for the input, everyone!
