20 recommended selections by type of design knife! Introducing the popular Olfa and Tamiya!

Design Knife 01, Shieldon

What is a design knife? If you use it as a hobby, you know it well, but if you don’t, you don’t know what it is. Design knives are knives that are active in paper-cutting and plastic model production, and are a genre that I would like to recommend as a hobby. This time, I will introduce the recommended design knives!


What is a design knife?

Unlike the so-called cutter knife, it is a knife that has a pen shape and the cutting edge can be replaced because it is used for detailed work such as cutting and making plastic models. Let’s compare its characteristics with a cutter knife and so on.

Design Knife 02, Shieldon

(1) A pen-type cutter knife with a sharp edge, that is, a sharp edge, suitable for fine cutting work. (2) There are two types of knife holders, a normal cutter type and a pen type. (3) There are various blade shapes, such as flat blades, curved blades, and saw blades, which can be used for various types of cutting.


Comparison of cutter knives and design knives!

The biggest difference between a utility knife and a design knife is that the shape of the main body is different, and as you can see by comparing the angles of the cutting edges, the angles are completely different.

Design Knife 03, Shieldon


Is the shape of the main body different between the cutter knife and the design knife?

Most design knives have a round shape like a pen. Therefore, when using it, you can operate the knife as if you were holding a writing tool, so you can perform detailed work in a stable manner. The cutter knife has a flat shape, and to use it, pull the blade straight to cut the paper.

Is the angle of the cutting edge different?

And if you compare the cutter knife and the design knife, there is a difference in the angle of the cutting edge, and the design knife is attached with the cutting edge at an angle of about 30 degrees. Generally, the angle of the cutting edge of the cutter knife that we use by folding the blade is made to 60 degrees.


This angle is used only for the purpose of cutting slightly thicker materials such as cardboard, but in the case of design knives, the angle of the cutting edge is 30 to 45 degrees, which is sharper than that of a cutter knife. This is because it is not a simple task such as cutting cardboard, but is suitable for more precise cutting work and plastic model work.

Cutting is easy by setting the angle of the cutting edge!

By making an angle like this, it becomes easier to see at hand, and there are features such as processing deep parts and making it easier to apply force to push through.


What are the drawbacks of design knives?

On the other hand, there is a demerit that the length of the cutting edge cannot be secured by angling the cutting edge. Therefore, it cannot be used to scrape large objects.

Differences in how to use a utility knife and a design knife!

What about a utility knife?

The utility knife is mainly used for cutting straight lines, and is used while supporting the main body with the palm of your hand. Therefore, the blade is on the blade so that it can handle a certain thickness, and when the sharpness drops, the blade is broken to improve the sharpness.


When you use it normally, you can use it in the same way as a “small sword”, and you can use it in the same way as using a knife, such as sharpening a pencil.

Design Knife 07, Shieldon


Be careful when breaking the blade of a utility knife!

If you want to replace the blade (to improve the sharpness of the blade) in the case of a utility knife, use pliers. Even if the sharpness is reduced, the blade of the knife is sharp and dangerous, and if you do not do it well, you will hurt your fingertips, so even if you make a mistake, do not use it to break the blade with your bare hands.


How to replace the cutting edge of a design knife?

Design knives, by their name, are used for fine clipping work such as design. For that purpose, the basics of cutting a design knife is to cut it in the same way as a pencil and use it upright so that it can be used for curved cuts.


However, since the blade edge is often chipped and only the tip of the blade is used, the blade is replaced one by one.


What is the use of design knives?

The design knife is used for cutting work when performing paper-cutting or paper crafting, and for model work such as making plastic models.


What are the precautions when storing design knives?

Design knives have the same shape as pencils and are easy to roll. Therefore, there is a risk of injury to the cutting edge. When not in use, cover the cutting edge with a cap to avoid injuring your hands.


Let’s prepare a replacement blade for the design knife

The cutting edge of the design knife is very delicate, so it may be difficult to cut it due to chipping during use, so it is important to always prepare a large number of spare blades.


The spare blade is the one that matches the knife you are using now!

Design Knife 08, Shieldon

Also, because there are variations in the structure and size of the base into which the blade of the design knife is inserted, not all replacement blades can be used in common. It is important to align the replacement blades that match the knife you are using.


What kinds are design knife?

Various types of design knives are sold by each factory, and there are two major factories, “Olfa” and “NT Cutter”, and Tamiya also sells design knives as an OEM from Olfa. In addition, special knives are also sold by “FEATHER”.


Which design knife is easy to get?

Among the design knives, the easiest to get is the “Art Knife 10B” sold by OLFA, whose blade is fixed to the knife so that it can be sandwiched between the plastic body, and this knife is from Tamiya. Sold under the name “Modeler’s Knife” and is appreciated by lovers of plastic making.


What about Tamiya’s Modeler’s Knife?

The Tamiya modeler’s knife is customed in a polygonal body shape, so it is not slippery and has a stopper to prevent rolling, which has been improved in consideration of modeler use.


High-end product of art knife!

The (OLFA Limited AK) model is wholesale as a high-end product of the art knife. This knife has a handle body made of full aluminum, and the fixed part of the blade to the knife has also been changed to metal parts, overall. It is customed to increase rigidity.


Also, because this knife has a full metal body, it weighs more than twice as much as an art knife, so it feels stable and comfortable, but on the contrary, it may feel heavy and easy to get tired.

Design Knife 09, Shieldon


Choose a design knife that suits your needs!

One thing to keep in mind when using a design knife is to choose a cutter that is suitable for the material to be cut and its thickness. In addition, it is important to select the cutter to be prepared according to the work, such as making plastic models and design cutting.
