I get several calls throughout the week about how to extend the life of the blade, or why aren’t my cuts clean anymore? Does this mean there’s something wrong with my machine? Well, unfortunately when the blade has seen the last of its days they’re just done. Nothing is going to bring them back; not increasing the pressure, or extending out the blade. They just reach a point where they are finished. What’s interesting about a blade that is going bad is that one moment the cuts will be fine, then the next cut there will be light feathering around the edges, and it very suddenly will get to a point that it won’t cut through the paper at all.
