cæter

Cúter is the term commonly used in Spanish-speaking countries for a utility knife, a handheld cutting tool with a replaceable blade. It is used to cut a wide range of materials, including paper, cardboard, vinyl, film, fabric, and thin plastics, and is widely employed in construction, packaging, crafts, and DIY tasks. In many regions, the tool is known simply as a cutter or box cutter, with cúter often referring specifically to the retractable-blade type.

Most cúteres feature a handle made of metal or plastic that houses a replaceable blade. Blades are typically designed to be replaced when dull and are often offered in sizes such as 9 mm and 18 mm. Configurations vary: retractable blades that extend and retract for safety; snap-off blade systems that allow rapid reshaping of the cutting edge; and fixed-blade craft knives used for precision work.

Common uses include opening boxes, trimming wallpaper, cutting vinyl flooring, shaping clay or leather, and performing delicate paper crafts. Artists and builders alike rely on blades for clean, straight cuts.

Safety considerations include keeping the blade guarded when not in use, cutting away from the body, using a stable cutting surface, and replacing dull blades promptly to reduce the need for force.

History and terminology: the modern replaceable-blade utility knife emerged in the early 20th century and has since become a ubiquitous hand tool. In Spanish-speaking regions, cúter is the common name; related terms include utility knife, box cutter, and craft knife.
