An X-Acto knife may be called an Exacto knife, utility knife, precision knife, or hobby knife. It is a blade mounted on a pen-like aluminum body, used for crafting and hobbies, such as modelmaking. Before the availability of digital image- and text-processing tools, preparing camera-ready art for use in printing (literal cut and paste or paste up) depended heavily on the use of knives like the X-Acto for trimming and manipulating slips of paper.

A knurled collar loosens and tightens an aluminum collet with one slot, which holds a replaceable blade.

There are numerous other knives on the market with very similar designs. Blades are typically interchangeable between different brands.

The original knife was invented in the 1930s by Sundel Doniger, a Jewish Polish immigrant to the United States.[1] He had planned to sell it to surgeons as a scalpel but it was not acceptable, because it could not be cleaned. His brother-in-law, Daniel Glück (father of poet and 2020 Nobel Prize in Literature laureate Louise Glück), suggested that it might be a good craft tool.

X-Acto office products[edit]

In addition to knives, blades and tools, X-Acto produces office supplies including pencil sharpeners, paper trimmers, staplers and hole punches. X-Acto sharpeners are electric, battery or manual. X-Acto has three types of trimmers: razor, rotary, and guillotine.

Boston brand[edit]

Through 2012, X-Acto sold ceramic and convection space heaters and fans under the Boston brand name.[2]
