As the cutting edge wears down, friction increases significantly.<\/p>\n\n\n\n<p>This creates:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Slower cutting speed<\/li>\n\n\n\n<li>Increased resistance through dense wood<\/li>\n\n\n\n<li>More pressure required from the operator<\/li>\n\n\n\n<li>Longer contact between blade teeth and the material<\/li>\n\n\n\n<li>Higher temperatures during the cut<\/li>\n<\/ul>\n\n\n\n<p>We often see installers continue using blades well past peak sharpness, especially during large flooring projects where gradual performance decline is less noticeable day to day.<\/p>\n\n\n\n<p>Over time, this almost always results in scorching along cut edges.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2
