SWRL/WRBL / Pencil sharpener


The SWRL pencil sharpener uses the natural movements of a person as the basis for how it functions. Rather than require a person to change how the pencil is held and follow a series of actions unrelated to writing or drawing, the SWRL is unobtrusive to the experience. No change in holding the pencil is needed, and overall sharpening time is less.
The sharpening track follows an intuitive and ergonomic motion – sharpening the pencil is as simple as drawing a circle. Microplane blades inside the track ensure a smooth cut from 360 degrees. A rubber pad underneath prevents slipping, so the SWRL won’t need to be permanently set in the workspace.
