About 5 years ago I bought a Fiskars Rotary Ruler Cutter at a Walmart store on clearance for $15.00 (originally $31.97) The ruler was great for a while but after much use it wouldn't cut anymore even with new blades. Every time I pushed the blade carriage down it only pushed down the smallest fraction of the blade and I'd have to make 2 or 3 up and down passes to cut through 2 layers of fabric. I even had trouble cutting one layer of fabric so I stopped using it. Very disappointed with this made in China product.
