The snap off blades are very thin and sharp, ideal for jobs that only need a short blade. My dad carries an Olfa knife in his shirt pocket with his pens and yes, pocket protector. He carries a 3"-4" folder in his pants pocket for tasks that need more blade. Strangely, I have never used an Olfa. The Stanley style retractable utility knife got me hooked years ago, but the Olfa makes way more sense for an office worker because it is so thin and light.
