OLFA 45mm Rotary Cutter Replacement Blades, 5 Blades (RB45-5) - Tungsten Steel Circular Rotary Fabric Cutter Blade for Quilting, Sewing, Crafts, and Scrapbooking Fits Most 45mm Rotary Cutters

Totally satisfied. These sell for $9.99 as singleblades so this is a great deal! Genuine Olfa!

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.

The case is convenient when taking classes and for storing at home. Quality edge cuts smoothly thru several layers.

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.

I used the original OLFA blade that came with the OLFA cutting tool to cut quite a number of cloth pieces, I liked the tool as it cut a clean line in the fabric. I bought these OLFA replacement blades which fit the OLFA cutter perfectly. My wife approached me today about the replacement blade not cutting cleanly like the ORIGINAL blade that came in the tool. I tested the cutting properties and she was exactly correct, the OLFA 45mm Rotary Blades, 5-pack blade which I just used to replace the original blade cut about 80% of the time and did NOT cut the other 20% of the time. I then proceeded to TEST the OLFA 45mm Rotary Blades, 5-pack blades and found that ONLY ONE new blade out of FIVE cut fabric cleanly. Mind you, I retested the original blade (yes I kept the original blade) and it still cuts a clean edge BETTER than four out of five OLFA 45mm Rotary Blades, 5-pack blades. I am not happy with these OLFA 45mm Rotary Blades, 5-pack blades as they are too expensive to be tossing four out of five in the trash... Not happy, something is wrong with these blades.

be very careful with these, super sharp

Stick with Olfa. I bought some cheap blades, and I got what I paid for. Olfa quality control results in a better product

You cant go wrong with olfa blades. They last longer than any of the others Ive tried! So sharp you dont have to press hard at all.

Worked fine. Get dull too soon

nice and sharp, I did not find they were oily as others have said. Cut right through the fabric as I would expect with the first pass and very little pressure applied. Great price considering I was paying a lot more for a 1 or 2 pack at a nationally known fabric store. When needed will definitely buy again.
