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

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!

Olfa blades are the best on the market. They are made of high quality steel, hold an edge very well, and cut sublimely. I have used off-brands thinking to get a bargain, but theyre not a bargain. These blades, while they are made for Olfa cutters (also the best on the market) will also fit on other brands of cutters (except for Martelli rotary cutters, which take Martelli blades only). They last a long time when used on a good quality cutting mat and when you dont hit things like pins when youre cutting. They can also be sharpened successfully a few times, which helps make them even more economical. I highly recommend these blades

You get what you pay for! The cheap blades are not worth wasting your money, the OLFA is the best and lasts the longest

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.

They have the OLFA name, are sharp and are brand new. Before ordering I had read reviews that commented on the blades being used, and not reflecting the OLFA name. I did not have any of those issues. The only issue I had was that Amazon didnt pack them well so they fell out of their container .

These blades have been great! I used one blade to cut a regular quilt plus two baby quilts and it is still cutting. The price is so great. I will continue to buy blade here!!! (I know that quilt shops have to stay in business but what they charge for blades is a crime and an insult to their customers!!)

At the price I can blades for frequently

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.

Ive been using Olfa rotary blades for quite a few years for cutting out sewing patterns and Ive tried others, but they just dont seem as sharp as Olfa. I like buying them in packs of five so Im always ahead of the need - and they are priced more economically.

I just got this order, but we use this brand all the time. Theyre sharp and the edge lasts a reasonably long time.
