I was tired of throwing away all the rolling cutter blades I use for a little while until they're dull. As a professional seamstress, I use a *lot* of them and it gets expensive, at $6-7 per package of five, less if you can find a coupon or something to use.
So I ordered this one and yes, it works well. It's like a reverse paper cutter; you leave the blade in the rolling cutter and run it up and down through this sharpener.
However, the one reason I really bought this one was to get more use out of the blades that might have a bit of a knick in them, you know, there you might have run up against a pin or something while cutting out a piece. It takes very little to make a blade skip in the cutting, sometimes on a new blade and then it's no good.
And this sharpener doesn't *do* that; it says that clearly in the instructions. It only sharpens, it doesn't get out the dings. *sigh* So I'll get a bit more use out of some blades but it's not as great as I'd hoped it would be.
I need to find something that re-grinds the little buggers back to true and sharp.
