Us the OLFA wheels if you cutting fabric that is difficult to work with or you want accuracy. You will need a large rubber pad for cutting so you can lay your fabric out flat. The only way to go. Harriete

The blades are super sharp And safely packaged. Great quality and value!

These blades are easy to replace. Amazing how much better a sharp blade cuts through layers of fabric. I always keep a supply on hand.

I use these blades to cut goody bags to be made for children at Shriners Hospital. The blades are very sharp and work exceptionally well.

These are not original Olfa blades, no way! I will only buy from local stores going forward. Shameful. 8/6/2020-UPDATED REVIEW I discovered the perfect remedy from a sewing blog regarding these blades. Use soft cotton to remove the oil from blade. Wipe blades gently with small amount of alcohol and dry using soft cotton. Blades will perform as expected.

Ive tried other brands blades but always come back to Olfa! They stay the sharpest longest, they cut through many layers of fabric at a time. (Ive cut 6!) which significantly cuts down on time when you are cutting itty bitty pieces for a quilt! Ive also cut paper with these blades so nice! Just make sure you close the safety on it as they are super sharp. Ill admit to a trip to the emergency room and some stitches when I neglected the safety on this... Also for the amazon.com price you cant beat even with a great sale at your local fabric/quilt/craft store!!!

Ive purchased cheaper blades from Amazon-- blades that bent or dulled after the first few minutes of cutting. Lets be honest, people buy a rotary cutter when theyre serious about cutting fabric. OLFA blades can go the distance. They dont bend or dull after the first pass. Ive had success using the same blade on multiple projects. Worth it.

I received a pack of 5 in the yellow plastic container. This I needed because the original blade that came in my new Olfa cutter was not sharp. These blades do come with oil on them, and were stuck together. I had to slide each one off to use. Some were sharp and lasted pretty well; others lasted less than one short cutting session. I do not cut a lot, nor do I cut many layers together. Yes I use a self-healing mat. There is no excuse for this poor quality. Now I think I know why blades at local stores are so much more expensive.

Blades easy to replace. Nice and sharp but blade has a defect where it consistently skips/doesnt cut a small section of fabric. Couldnt see a chip or dent in blade, must be a slight flattened section. Haven’t tried other blades. Usually olfa is superior.

Unlike most others I actually bought these blades for cutting paper and they have worked flawlessly for this purpose. The cuts need to be precise and consistent (trimming book text block edges) and so far Ive been very happy with the results. Only trimmed a couple blocks so far so jury is still out on durability. Also a couple stats as I couldnt find these in the description: 1) The metal disk is 0.3 mm thick. 2) The blade has a bevel on both sides and it appears to be around 7 degrees (hard to measure effectively).
