Abstract

A ring handle for a craft knife that is configured to securely hold a cutting blade by forming a friction fit with the cutting blade and without engaging with a hole or notch in the cutting blade. The craft knife handle includes a blade slot recess that is formed with a ridge or tapered section that is adapted to abut with the edges of the cutting blade that are inserted into the blade slot. The craft knife handle also includes a collar that engages with the handle body of the craft knife handle to secure the cutting blade within the blade slot. The craft knife handle may also incorporate a no-roll design with at least one facet of the handle being flat.
