    Rotary blade of choice

    Ive purchased cheaper blades from Amazon-- blades that bent or dulled after the first few minutes of cutting. Lets be honest, people buy a rotary cutter when theyre serious about cutting fabric. OLFA blades can go the distance. They dont bend or dull after the first pass. Ive had success using the same blade on multiple projects. Worth it.

    Im a quilter and I ordered two 5-packs of these 45-mm blades and Im very happy with them. This was basically half price what blades normally cost and while mine stay sharp for awhile, I like to keep replacement blades on hand. These are in sealed 5-pack containers, just the same as they are sold at JoAnns or Hancock Fabrics. I usually only use my rotary cutters for cotton quilting fabrics so they last a long time. If you are cutting paper, leather or otherwise hard or thick materials, they will work fine, they just wont last as long as when used only for cutting thin cotton fabric.

    I cut fabric strips for quilt tops. I started with Fiskars rotary cutters, but they wobbled and skipped on me. Olfas are more reliable, but like any razor-sharp tool the blades dull and need to be replaced--pretty frequently. Replacement rotary blades in big box fabric stores in my city have become outrageously expensive, and rarely can I find a 5pk. It was a no brainer for me

    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 use my cutter with sharp blades to cut strips for quilting. Accuracy is very important to me, so having a sharp blade that cuts accurately is very important

    What a difference to have these blades on hand! Cant cut fabric cleanly without them.
