Utility knife: 18mm width is the most conventional blade. There are also 9mm, 18mm. There are two kinds of materials: zinc alloy and aluminum alloy. Our company also makes two types of utility knives, namely retractable utility knife and folding utility knife.
The high-quality cutter head has back-and-forth elasticity. This is not a product problem but to protect the ruler.
Folding utility knife is a relatively common utility knife. The handle is made of aluminum alloy and TPR plastic to ensure firmness and hand comfort during use. Push out the knife head of the folding utility knife before use and shake it to see if there is any sound. If the blade is fixed, it can be used normally, and the sound can be ignored.
There are two styles of Retractable Utility Knife. You need to shake it before use to determine whether it is safe to use. One is a utility knife that uses a combination of TPR plastic and aluminum alloy. It is larger in size and uses a trapezoidal blade with a grip. There are three extra blades in a slot, which is convenient for replacing the blades at any time, and the price is relatively expensive.
The other uses a long strip blade. The saw blade needs to be pushed out during use, and the cutting range is relatively large during use. However, you should be careful not to hurt your hands by the strip during use, and try not to extend too much , Pay attention to safety when replacing.
