OLFA 18mm Heavy-Duty Snap-Off Blades (LB-10B) - Japanese Steel, 10 Blades | Japanese tool steel, 8 segments per blade, 10-pack, all 18mm - Heavy-duty construction - Contractors and Construction

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.

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.

They are very sharp and better quality.

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.

I little difficult to advance the blade, otherwise fine.

Ideal for many uses. I've used them for years.

I love this blade. I am trying to do some crafting with cardboard, This makes it so easy and the cuts are more precise,

Great replacement blades. They're durable and hold an edge quite well too. Excellent product. My OLFA knife is perfect to keep in my toolbox drawer to open or breakdown cardboard boxes.

These are great blades , very sharp

have always used these blades and they are excellent although they have doubled in price since I last bought them !

After much hemming and hawing over the many Olfa-compatible snap blades on Amazon, I am glad I settled on these ones. They're exactly the correct fit for both my utility knives (see photo), one an actual Olfa and the other some random off-brand of long-forgotten provenance. I've had them both for years and they were rusty and down to their last segment; now they both feel like brand new knives. These replacement blades are well packed for storage and 8 should last my two knives for years.Amateur tip: it turns out "18mm" refers to the vertical height of the blade, perpendicular to the cutting edge. I had to slide my existing blade out the back to measure it accurately due to the remainder being too short to measure vertically out front.

olfa blades for an olfa knife. just as God intended. 8 pack is a great option for a casual user like me.

They're completely fine replacement blades. I feel they get dull a bit too fast (mostly using on cardboard boxes), but don't really have anything to compare them to.
