I use the True Cute Blade Sharpener from Grace, but I bought mine at Quilt in a Day.com
If you use it correctly it works well. Even tho it's expensive the money I save from not buying new blades more than pays for the $40 I spent on the sharpener. I think I'll be sure to wipe off the blade before cutting fabric to take care of the shavings. I didn't even think about that.
I figure it's the same when my DH sharpens our kitchen knives. Don't really want shavings in the food!
