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

I sew a lot, and I use a rotary cutter and mat to cut out my pattern pieces. Heres my review of these blades. Positives: Can cut through whatever fabric with ease (while it stays sharp) Provides clean cuts The sharpness of the blade lasts longer than you would think it would (several months) Negatives: None, really, except a caution to be careful with these blades, as they are extra sharp

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.

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.

Name brand is better! Original packaging, looks like what I would buy in the store. Great price too! I would order these again from these folks.

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.

quick delivery good price

At the price I can blades for frequently

What I disliked about this product is that it is very dangerous to try separating the blades!! They are stuck together like glue and it would be extremely easy to cut yourself badly trying to separate the blades! They should have put something... anything in between to make it easier to get them apart. I fear someone is going to end up in the emergency room from trying to get the blades apart! I had to be extremely careful as I am on blood thinners and at this time, with Covid-19 rampant, it would not be a good time to have to go to the E.R.!

These are the real thing, the best brand for rotary cutter blades. Sharp enough to slice off a fingertip if you dont 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 didnt cut as well but surely dulled the blade which is why I was glad I had four more to play with.
