I have a new favorite ruler!
Sullivans recently came out with "cutting edge rulers", designed by Pat Sloan (one fun quilter, let me tell you!). I was intrigued from the moment I saw them, so of course I had to try one. I got this one: The Cutting EDGE Frosted Ruler-6-1/2X12-1/2.
I've been using it for a couple of months now, and I do indeed love it. It has a 650 grit Diamond Cabide edge that purports to sharpen your rotary cutter blade as you use it, and by golly, I believe it's working! I've got a regular blade in my cutter right now, and I've been using it -- daily -- since I bought this ruler and it's still cutting like a new blade. Now *that's* something to brag about!
Do I think these rulers will prevent me from ever having to buy new blades? Of course not. But I'm happy to extend the lives of the ones I do buy -- like my mama always said, "a penny saved is a penny earned".
Sullivans has a complete line of "The Edge" rotary cutting tools in addition to the rulers: cutters, blades and mats. My next "test" will probably be a mat; I'm in the market for a new one. Next time you're in the market for a new quilting or scrapbooking ruler, give one of these a try. I think you'll be pleasantly surprised.
