45mm Rotary Cutter Blades (10 PACK) - Fits All : Fiskars & Olfa - Craftopology Replacement Blade Set, SKS-7 Japanese Steel. Best for Quilting, Sewing & Fabric with Bonus Marking Pen + Storage Case

I've owned my first Rotary Cutter since Christmas. Whenever I used it, I thought "Shouldn't this be a bit easier?" because I had to press down fairly hard to get a good cut. Tough on the cutting mat, too. The other day, I decided to research what to do with dull rotary cutter blades. "They" said either sharpen or replace. Who knew!!! I certainly don't want to mess with sharpening (I'm a klutz) so I bought this set of replacement blades. I am so glad I did! Super sharp! I really notice the difference when cutting - a much easier, smoother action. And they come in a nice storage box. I would definitely recommend these for anyone who's rotary blade isn't performing up to expectations.

I've only cut a few things since I received your blades, but they were perfect. I often have toreally lean in on my rotary cutter for the blades to cut--I didn't have to with these. I felt like one of the professional TV sewists!

Great blades at a great price. Got sick and tired of paying high prices for a single blade at the major fabric and hobby stores. I would try to use the blades far longer than I should have. Now I feel much better about replacing the blade when it starts to dull -- which isn't that quickly.

Well, I'm looking at the reviews on this item and I'm truly baffled! They are not sharp, and have shredded my material. The pen that came with the blades has not disappeared as of yet! Extremely disappointed to say the least! 😔 A waste of money. If I had a choice in giving a negative star rating, I would!!!

This is an excellent product! Ten super sharp blades in a package for the price of one at Joann's! One blade will cleanly cut through six layers of cotton! I did not get that efficiency with a he much more expensive blade!

Reasonable product. Purchased for my wife. She says they do not last as well or cut multiple layers of fabric as well as the ones she purchases from a local quilt shop. Unfortunately the quilt shop bundles are not always available.

These were not sharp. Wasn't able to use them after a few cuts, even on a self healing mat.

I bought these over a year ago and finally started using them. First blade had a bad spot on the blade so it wouldn’t cut cleanly. Switched blades...same thing! Don’t buy these!
