There are a few different reasons you might want to flatten your Cricut. If you notice that your Cricut is not cutting as deeply as it used to, this could be a sign that the blade is dull and needs to be replaced. If you are having trouble getting your Cricut to cut through thicker materials, flattening the blade may help. You may also want to flatten the blade if you notice that the cuts are not as precise as they used to be.
To flatten your Cricut blade, start by removing the blade from the housing. Next, use a sharpening stone or diamond file to lightly file down the blade. Be sure to only file in one direction and avoid applying too much pressure. Once you have finished filing the blade, reinsert it into the housing and test it out on some scrap paper.
