I give 5 stars when the description is accurate and I have no negative feedback. Good price. Good quality. Very sharp. Will buy more when I run out.

Snaps off perfectly!
Have you ever struggled to snap off blades before? If you feel cheated by those hard-to-snap-off blades, OLFA will not disappoint! Blades break off easily (not during use, I mean when you intentionally want to break off the blades) and each level it breaks off, it works like brand new blade! If you're a frequent user of these box cutters, you know some brands break off not by the line, and they don't work like they're new because they don't break off properly.

VERY SHARP AND VERY GOOD!
Best knife ever! We watched some YouTube videos to get some tips on insulating a basement. The guy on the videos we watched highly recommended this knife for cutting insulation. We used Rockwool. It does a great job and we highly recommend it.
