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

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

Wish blades lasted long. Use blades for cutting fabric for quilting.

Olfa replacement rotary blades are the very best. When you pay good money for beautiful fabric you sure dont want to take a chance on messing up when cutting. I comparison shopped all over, brick and mortar stores also, and Amazon is my choice for this product. Quilters were recently discussing using rotary blades for a carpet cutter from a discount hardware provider in lieu of the real thing because the cost was so attractive; not a good idea. Quality tells in the long run.

I fiddled around with generic blades and had to change them often. These Olfa are something to write home about. They are good, sharp and last a long time. You get what you pay for. I wont be buying anything else from here on out.

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.

CT SELLER had the best price Ive been able to find! Any quilter knows that we go through rotary cutting blades very quickly and refill packs are always on our shopping lists. The blades were received in a timely manner and I wish I had ordered more than 2 packages. My daughter (another quilter) was really upset that I had not ordered some for her too! Mary

The blades I received were all stuck together, presenting a very dangerous situation. I finally managed to separate one using hemostats and tweezers but the whole time I was scared I was going to cut myself. The blades need to be individually packaged for safety! Once I was able to separate one of the blades and attach it to my Olfa 45mm rotary cutter, the new blade was duller than the original blade being replaced. I requested a refund from the seller and it was approved; however, I have to pay shipping to return the blades and the sellers shipping is going to be deducted from my refund. Additionally the seller is stating that my problem is the size of the blade not fitting my cutter. I never said there was any problem with the blade fitting my cutter. My cutter is 45mm and the blades are 45mm. I am very disappointed and will never do business with this seller again.

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).

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.

I quilt all the time and need sharp blades at a reasonable price. This fits the bill. I highly recommend and will be ordering more from this company.
