Types of Hobby Knife Blades and Their Uses

Light-duty blades are usually smaller and fit into a standard handle. They’re good for small projects that require precision and targeted cutting, carving or shaping. These thinner blades are essential for detailed work, often used by artists and hobbyists working with paper, vinyl, or other delicate materials.

Medium-duty blades are a bit larger and have a wider shank. This means they require a different handle meant for a larger blade; the Excel Blades K2 handle is a good example. Medium-duty blades are versatile and can handle thicker materials like foam board, balsa wood, or fabric, making them a great all-around option for a variety of crafting and DIY projects.

For tougher jobs, heavy-duty blades are the way to go. These thicker, more robust blades are designed to cut through materials like wood, leather, and carpet or drywall. Chisel blades and heavy-duty utility blades fall into this category, offering the strength needed for more demanding tasks while maintaining precision.

Be sure to check which handle is compatible with your blade, as not all handles fit every blade. Blade numbers, which are typically indicated on the packaging, correspond to specific handle sizes, so it’s important to match them correctly for a secure fit and optimal control. We’ve listed some of the most popular blades below, along with their corresponding uses, to help you find the perfect match for your project.

The most popular blade is the #11 – used by paper artists, paper illustrators, polymer clay artists, designers, cosplayers and more! You are sure to find this blade in every creative studio. To learn more about the #11 blade and other blades, keep reading!
