OLFA’s fully automatic safety knife has a spring-activated, rounded-tip RSKB safety blade that self-retracts when it loses contact with the cutting surface. The built-in safety guard activates when cutting begins and cannot be overridden. It has a fiberglass-reinforced ABS handle and a lanyard hole.
Fiskars’ Pro drywall utility knife has a jab saw to punch through drywall, a CarbonMax blade coating, two-blade storage capacity, tabs that ensure the blade won’t pull out when twisted and multiple Softgrip hand grips for better ergonomics. The blade and saw deploy from the same end to prevent accidental release, and the knife hinges open for cleaning.
