The ZoLNiF (ZOL + knife, spelt in NQaLF) is a new design to replace the ubiquitous and often imitated X-Acto hobby knife that has been around since the 1930's and it's newer updated versions, such as the Gripster.

The ZoLNiF is ideally molded in carbon fiber composite or other high strength re-enforced resin, but can also be machined, forged or 3D printed.

It improves ergonomics and function over all previous designs. The blades cannot be pulled out, even when deeply embedded in wood. Holes can be reamed without unscrewing the collet. Replacing the blade takes less time.

The prototype shown was machined from 7075-T6 aluminum. It is the simplest 2 piece version. The design can be enhanced with the addition of a spring to aid opening, another to eject used blades, blade gripping rubber inserts, finger grip inserts, etc.
