SK2 Best Utility Blades Zinc Alloy 18mm Cutter Knife For Professional Use

Blade Description

Classification by Material
1.High-carbon steel blades: Cost-effective with moderate sharpness, suitable for daily cutting of ordinary materials such as paper and cardboard. However, they are prone to rust and need to be stored in a dry place.
2.Alloy steel blades: Added with alloy elements like tungsten and chromium, they have higher hardness and wear resistance. Suitable for cutting slightly harder materials such as plastic and leather, and have a longer service life than high-carbon steel blades.
3.Stainless steel blades: Excellent in rust resistance, suitable for use in humid environments such as cutting food packaging. Their sharpness and hardness are slightly inferior to alloy steel blades.

Classification by Purpose
1.General-purpose blades: The most common type, suitable for most daily cutting tasks such as unpacking, cutting paper, and films.
2.Heavy-duty blades: Thicker (usually over 0.6mm) and made of stronger materials, suitable for cutting hard materials like thick cardboard, rubber, and thin metal sheets, often used in industrial scenarios.
3.Precision blades: Thinner and sharper with a finely designed tip, suitable for precise cutting such as model making, crafts processing, and cutting of electronic component packaging.
4.Safety blades: The edge of the blade is specially treated (such as a rounded design) to reduce the risk of scratches during cutting, suitable for children's handicrafts or scenarios with high safety requirements.

What is utility knife ?

Designed to be lightweight and easy to carry and use, utility knives are commonly used in factories, warehouses, construction projects, and other situations where a hand tool is needed to mark cut cable, trim plastic or wood materials, or to cut tape, cord, strapping, cardboard, or other packaging material.

Application

1.Packaging and Unpacking: Ideal for opening cardboard boxes, cartons, shrink wrap, and tape-sealed packages, making them essential in warehouses, shipping centers, retail stores, and households during moving or receiving deliveries.

2.Material Cutting: Suitable for trimming a range of materials such as paper, cardstock, foam, rubber, vinyl, leather, and thin plastic sheets. This makes them useful in crafts, DIY projects, upholstery, and sign-making.

3.Industrial and Construction Tasks: Heavy duty utility knives with robust blades can cut through thicker materials like corrugated board, light-gauge metal, insulation, and rope, supporting work in construction sites, manufacturing facilities, and workshops.

4.Precision Work: Smaller utility knives with fine blades are used for detailed tasks such as model making, scrapbooking, electronics repair (cutting tape or packaging for components), and trimming delicate materials with accuracy.

5.Household and Daily Use: From cutting wrapping paper, labels, and plastic bags to trimming garden ties or opening food packaging (with food-safe blades), they serve as a handy tool for everyday cutting needs at home.
