Automatich safety knife with 3 sided slider. For work with triple-walled corrugated board boxes. MAXISAFE adapts to the type of cut required at the time, be it sideways, horizontal or straight from "up top". Designed for a minimum of effort at a maximum of efficiency. Ergonomically styled plastic handle with metal wear-protector at the blade outlet. For use by right- and lefthanders. "GS-TESTED FOR SAFETY". Easy blade change: no extra tools required. Typically, users of safety knives with automatic blade return needed to be trained to release the blade slider during the cut in order to enable the auto-retract function. Only minimal training is necessary. The ingenious mechanism within the MAXISAFE will automatically return the blade to the safe position at the end of each cut regardless of the position of the blade slider. Replacement blades: 1024827
