I use snap-off utility knife blades a lot. My current set of blades is amazing (otherwise I wouldn't be writing about it). One use is for cutting a group of paper towels into quarter sections. With my last set of blades, the point had to be snapped off after three or four uses. The current blade is like one of those Ginsu knives advertised on TV, except for real. It's a Stanley # 11-301 with "ENGLAND" stamped into the blade. I vaguely recall having them before, but don't recall the extreme performance. The utility knife I used last was a Rubbermaid abortion, so maybe I just got used to ultracheap blades (whatever blades that came with it).
Have fun.
