Knives & Cutters

About this category

Knives and hand cutters are general-purpose cutting tools made of a sharp steel blade fixed in a plastic or metal body that provides a hand grip. They fall into three principal families: fixed-blade utility knives that are sharpened and resharpened over their service life, knives with replaceable blades where the complete blade is swapped out when worn, and snap-off blade knives whose blade is divided into segments broken off during use to expose a fresh sharp section. These tools are used to open boxes and cut cardboard, light plastics, adhesive tape and rope in warehouses and general installation environments. Blade safety design varies between models and may include locking or retracting mechanisms in some models but not others; each manufacturer defines the features present in its product. Hand knives are not substitutes for specialized cutters designed for metals, pipes, cables or fiber-reinforced materials, because the blade may break or slip on such workpieces. Powered utility knives, pneumatic cutters and fixed industrial cutting machines are excluded from this category. Industrial buyers select models based on the materials to be cut, the blade safety mechanism, the ease of blade replacement in different work environments, and the grip ergonomics for repetitive cutting operations, along with any site-specific requirements for retractable or locking blades in handling-sensitive areas.
