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 products are always a safe buy.

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

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.

Opened package today as Im making face masks. I put the disk downs on my fabric and noticed an odd smell. Then, as I tried to put one of the new blades into the rotary cutter, I noticed my hands were greasy and there were grease stains on my fabric. I had never noticed oil on previous blades Id bought. Theres a coating of CLEAR OIL on each of the blades. Update: Nt just a light coating, but one that drips off the blade Horrible. It is suggested I wipe off the oil, but theres no way to safely get the oil off - remember these disks are sharp, and no way to cut fabric without getting oil on your fabric. Really a huge disappointment and the company should include better instructions on how to remove oil.

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.

Could not cut with the blades that came with my cutter. These blades made all the difference....cut like BUTTER.

Have used Olfa rotary tools for years and wouldnt use anything less. These are top quality blades.

Love the fact that these come in a little package so that I know where the blades are and when I change one I can put the used one back in the package. I usually, mark the old blade with an X with a sharpie so that I know not to use again. Its also a safe way to dispose of the blades.

I have used these for years. I wish they would stay sharp a little bit longer. I have a sharpener but it isnt the same as a new blade, of course.

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