Brief Introduction to Hobby Knife

A hobby knife is a traditional tool that features a handle with a pointed, replaceable blade at one end that’s about an inch long. The blade is mounted on a pen-like aluminum body. As a handy tool for use in the creation of various craft projects, the hobby knife is a single-bladed knife that easily cuts through a variety of different materials, making the task of engaging in craft projects much easier. It may also be called a utility knife, or precision knife.

Characterized by a single sharp blade, the body or handle of the craft knife may be composed of wood or metal. The metal types of craft knives usually allow the blade to be inserted into the body by opening the two sections of the knife, placing the blade in the chamber, and then resealing the body with the use of a single screw. The blade can be retracted or exposed with the use of a slide mechanism on the side of the body.

The Usage of Hobby Blade

Hobby knives can be used in a variety of ways. They’re not just used by hobbyists, but by artists, designers, seamstresses, soap makers, and DIYers, to name a few. They’re used to trim, carve, cut, and make shapes in materials like plastic, paper, leather, and even wood. Here are some of the common uses for hobby knives: scrapbooking, cutting fabric, bookbinding, and wood carving.

Craft knives are used for cutting and shaping light materials, such as cards. Thus, the hobby knife is ideal for use with any type of paper craft. Whether the paper is relatively thin or is composed of stiff cardboard, a good quality craft knife will easily make a clean cut. This type of knife is also great for use with sheets of plastic of varying thicknesses, making it easy to score a seam and then pop the two sections apart. What’s more, they are very useful during the model-making stage of the design process.

The Types of Hobby Knife Blade

There are various hobby blades available that can attach to a hobby knife to be used for different tasks.

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.

Medium-duty blades are a bit larger and have a wider shank. This means they require a different handle meant for a larger blade.
