Thanks so much for the link. I went to our local Harbour Freight yesterday, but the clerk had not heard of such a thing. Now I have the picture and the lot number of both the blade and the cutter. The cutter looks interesting, but we'd have to figure out the size of the base in order to cut accurately. I t would push the blade past the edge of our rulers, but wouldn't it be a great way to keep our blades straight up & down?
