The PRIMEdge ROBO-EDGE fully automated knife sharpening system sharpens knives in 60 seconds or less. The robotic sharpening system uses minimal parts and durable, long-lasting materials — and requires only one operator. Capable of sharpening at least 60 knives an hour, operators can simultaneously test knife sharpness, refurbish other dull tools or conduct other tasks. The system also eliminates downtime with dual retractable drawers that allow one tray to be loaded while the other tray is being sharpened. In less than 60 seconds, each knife is hollow ground, honed, polished, and returned to the tray as the next knife is selected.
