I wouldn't try for that many layers. By the time you get them stacked to line up you could cut several times. I have several Martelli cutters and I find the blades last longer in them than in the Olfa even though they are the same blades. The only thing I can think of is that because of the way it is held it is more stable while cutting and preserves the blade. I have been cutting lots of strips with the Shape Cutter and have not replaces the blade.
