OLFA 5004 L-2 18mm Rubber Inset Heavy-Duty Utility Knife

I have had an OLFA L-2 for 30 years. I still have it. I originally bought it at an art supply store in Chicago. I love the break off blades. When the razor sharp blade becomes dull, just push out the portion that is dull and snap it off. Then extend a new section of blade that is sharp and keep on cutting. Blade replacement is simple and fast. I like the L-2 version of the knife because of the rubber grip. The rubber has never come loose, and has never dried out. After 30 years of regular use the old knife has developed a very tiny crack in the yellow plastic, but keeps on going and I don't ever notice the crack. I like the bright yellow because I can always find my knife wherever I lay it down. I just bought 2 more after all these years because I'm getting lazy having to go back and pickup my knife where I keep it. So now I have them in multiple handy locations. There are other knockoffs, but this one is still the best with the best feel in your hand.
