The difference between carpet knife vs utility knife lies in their design, purpose, and functionality. Design: A carpet knife typically has a slim, pointed blade designed for precise and intricate cuts on a soft cutting surface like carpets. In contrast, a utility knife usually has a wider blade suitable for general-purpose cutting and may feature a retractable blade mechanism for adjustable cutting depth. Purpose: Carpet knives, or carpet cutters, are specialized tools primarily used for cutting and trimming carpets. Utility knives, on the other hand, are versatile cutting tools suitable for a wide range of applications, including construction, woodworking, packaging, and general cutting tasks. Functionality: Carpet knives or carpet cutters excel in providing precise and detailed cuts on soft materials, making them ideal for carpet installation and customization. Utility knives offer flexibility and adaptability, allowing users to adjust the blade length and handle various materials.
