Pro-Tip: When cutting thick materials like asphalt shingles or heavy carpet, use the hook blades provided in the magazine. Pulling the hook through the material from the underside (or with a pulling motion) utilizes the material's own resistance to help the blade bite, resulting in a much cleaner cut with less risk of the blade slipping compared to a standard straight utility edge.
