These are the real thing, the best brand for rotary cutter blades. Sharp enough to slice off a fingertip if you don't move 'em in time (ER doc said leave the surgery to the surgeons). I have cut interfacing, six layers of fabric and got a nice clean cut. Corrugated cardboard didn't cut as well but surely dulled the blade which is why I was glad I had four more to play with.

These are the best blades. The generics are not worth it. This metal is different than others. I can cut through multiple layers of fabric with ease. These blades last a long time and do not slowly chip like cheaper blades. Others that I've tried will either not cut, or will only cut 1-2 layers, or worse they will get chipped and leave a dotted line of uncut fabric. These blades are strong and long lasting. I love them!

Just what I was looking for! I borrowed a rotary cutter from a friend for a quilt project and noticed that there was a "fault" in the cutting blade, so that the cutter didn't quite cut through every 5 inches or so. I replaced the blade and Voila, clean cuts. Plus it flet good returning the tool to the owner with new blades. Nice to have gotten replacement blades from the same manufacturer as the cutter, OLFA. Blades made in Japan, very high quality. Very pleased with my purchase.

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 I've 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 couldn't 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).

I live in the country so its about a 12 mile drive to the closest place to get replacement blades. Not a far drive but inconvenient when you are in the middle of a project. These blades were delivered quickly and are perfect for my needs. Will definitely order again as needed. Great price too.

These are great blades. Very sharp and lasts a while. I use them to cut across several layers of fabric at times. New, unopened package. Arrived quickly without prime.

Only Olfa cutters and blades for me. You get what you pay for. These are for my business, and fooling around with cheap blades and cutters is a waste of time, and dangerous. If you buy an Olfa cutter, USE the Olfa blades.

I've purchased cheaper blades from Amazon-- blades that bent or dulled after the first few minutes of cutting. Let's be honest, people buy a rotary cutter when they're serious about cutting fabric. OLFA blades can go the distance. They don't bend or dull after the first pass. I've had success using the same blade on multiple projects. Worth it.

So sharp! Easy to change out and replace in my 45mm rotary cutter.The case is nice to have to store and dispose of the used blades. Cuts through several layers of fabric like a dream!
