How to choose a cutter

Cutters are useful for cutting paper, but in fact there are many different types of cutters. Selecting the appropriate cutter according to the material to be cut and the situation in which it will be used will improve workability and safety. Keep several types of cutters on site or in the office, and learn how to use them properly for different tasks.

Utility knife

Utility knives are working cutters that can be widely used for general tasks. There are several types of blades available, so choose the one that best suits your needs.

Oversized blade


This is a large blade with a width of 25 mm and a blade thickness of about 0.7 mm. It can be used for thick materials such as plywood and wood, etc.

L-shaped blade


It can be used for a wide range of applications, from delicate cutting of paper, etc., to thicknesses as thick as plywood.

M-shaped blade


This blade is positioned between the L-shaped and compact blades, and combines dependable cutting comfort and small turning capability.

Compact blade


With a thin and small blade, it is suitable for cutting paper and other thin, easy-to-cut materials as office supplies.

Black blade


The black blade is tempered to give it a black color and sharp cutting ability.

Art blade


This cutter is used for paper crafts. The tip of the blade is very thin, making it suitable for delicate cutting work with a high design quality.

Hook cutter


This cutter is specially designed for unpacking. When unpacking cardboard boxes, using scissors or bare hands with excessive force can lead to accidents. By using the special opener, unpacking can be done easily with minimum force.

Plastic cutter


This cutter is suitable for cutting plastic plates and other materials. It is used when you want to cut acrylic, polyvinyl chloride resin boards, plastic boards, etc. The method of use is different from that of ordinary cutters, and it is characterized  by running the cutter along the board while holding a ruler or the like as a guide, and then breaking the board by hand along the groove.

Circle cutter


This cutter is used when you want to make a circular cut. It uses the principle of compass to obtain a circular cut, and depending on the product, it can even cut thicker materials such as cardboard or plywood, etc.

Circular blade


Also called a cloth cutter, this cutter can easily cut soft and difficult-to-cut materials such as cloth and film. The disc-shaped blade rotates to cut the object, so if the object is thin and soft, it can be easily cut by holding it with one hand and lightly pushing it forward. Since the cutting is done by pushing the blade by hand, the shape of the cut, such as curved or corrugated, can be freely adjusted.

How to use the utility knife properly

Utility knives are familiar daily necessities, so we tend to use them casually. However, if handled carelessly, they can lead to unexpected accidents such as injuries or damage to objects. The following precautions should be kept in mind.

Suitability for work

Select a cutter suitable for the material to be cut, the thickness of the material to be cut, and the cutting line (straight/curved).

Condition of the cutter

The blade to be used should be sharp and not dull. If the blade is pulled out too much, the pressure of cutting will cause it to break and the blade to fly off, so a small amount of blade edge is sufficient. For screw-type cutters, make sure that the screws are tight and secure before use.

Worker's condition

Since it is a blade, avoid using the cutter when the operator is not concentrating, when he/she is tired from continuous work, or when his/her hands are badly covered with grease or other contaminants.

Method of cutting

Work in a correct and comfortable posture, and on a stable stand or other stable surface. If a guide is needed, use a ruler or similar object of sufficient thickness. Do not place your hand or any object in front of the blade's advancing edge. When you finish cutting and put the cutter down, be sure to put the blade away, even if it is just for a short break.


Keep the cutters tidy and in order and keep them away from moisture. The next time you use the cutter, make sure the threaded parts and blade are not rusted.


Cutters are convenient tools that can be used in a wide range of places. However, even if it is easy to use, handling it carelessly may cause accidents and injuries, so be careful not only in selecting a blade that matches the object, but also in the type of the blade and your posture.
