OLFA NA-1 utility knife has rubber grip providing extra stability and control. Not only sturdy, its handle is resistant to acetone. You'll appreciate the steadiness of the knife when you use it to cut packaging, tape, shrink wrap, vinyl, window film, wallpaper, caulking, foam board and other materials. Keep one knife in the house, one in the basement and another in the garage, so you'll always have one close at hand. Great for applications such as paint, window film, and packaging. Includes one ABB blade which fits any OLFA 9mm heavy-duty snap blade knife. Order replacement blades shown at right.
