Snap-off blades might be the most popular option for utility knife blades. A Japanese manufacturer called Olfa Corporation invented the snap-off blade in 1956. These blades are uniquely designed as one long, sturdy blade that you can expand to cut through fiberglass insulation.

And snap-off means faster change-out. It applies a one- to two-second technique involving a pair of pliers or blade snapper, which yields an instant sharp edge the second the dual-edge segment of the dull blade is snapped. There are three different common sizes of hobby knife blades: 9mm, 18mm, and 25mm.

Serrated edge blades are fantastic utility knives for cutting dense materials. Serrated knives, with their scalloped, toothlike edge, are ideal for cutting through foods like a loaf of crusty bread with a hard exterior and softer interior. The principle behind a serrated knife is similar to that of a saw: The teeth of the blade catch and then rip as the knife smoothly slides through the food. They typically range in length from 4-7 inches. Usually, long knives are suitable for cutting carpets and vinyl flooring. In addition, they can be used to cut a variety of foods, such as bread.

There is no difference in design between a serrated blade and a scalloped blade. What makes them different is the style of cutting or shredding the material. Serrated blades are used for sawing, while people use scalloped blades for cutting. The serrated blade has a rougher edge than its counterpart, and this design provides protection for the user.

  • 6. Pointed tip knife

FAQ

Here are some questions you may want to figure out.

The blade of a craft knife is usually made from steel. Steel is a material often used in the manufacturing of tools due to its strength and comparatively low cost. The steel used is often heat-treated, to bring the blade to a hardened state. Connect us if you are interested in the manufacturing process. You are welcome to visit our factory at any time.

2. When should I replace the blade of my hobby knife?

    1. Rust.

Because of its single-use nature, the blade of a utility knife tends to rust more quickly than the blade of a regular knife. If you’ve been using the knife long enough that it rusts, it’s definitely time to replace it.

    1. Problems with extending and retracting the blade.

These can point to structural problems with the knife itself, so make sure it’s not damaged or stuck with some kind of debris. However, it is also possible that damage to the blade is preventing it from working properly. Very dirty or rusty blades often cause these problems.

3. Can I sharpen my utility knife?

Of course, you can. In order to protect your utility knife from rusting, sharpening your knife from time to time would be a good idea. Or else, you will have it simply replaced. However, there will always be an option to remove the blade from its handle and sharpen it on a wet stone or other sharpening kit. This is why you need to know how to sharpen your utility knife. Snap-off blades don’t have this question. Once it does not work well, snap off it.

4. Are utility knives universal?

Yes, most of them are although their certain shapes might not look the same. Keep in mind, however, that some snap-off utility knives won’t accept a standard blade.

So before purchasing, you can ask for details data on the knife from the supplier, and if you have special requirements, you can contact manufacturers to customize it.
