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

Take care with these when you are cutting fabric. I learned very quickly to retract the blade after each cut because one little tiny slip and you have a nice deep cut on your finger just from barely touching the blade. Each blade was able to cut all of the pieces for a queen size quilt with each piece being about 2 inches across.

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).

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

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

Rotary blade of choice

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.

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.

I used the original OLFA blade that came with the OLFA cutting tool to cut quite a number of cloth pieces, I liked the tool as it cut a clean line in the fabric. I bought these OLFA replacement blades which fit the OLFA cutter perfectly. My wife approached me today about the replacement blade not cutting cleanly like the ORIGINAL blade that came in the tool. I tested the cutting properties and she was exactly correct, the OLFA 45mm Rotary Blades, 5-pack blade which I just used to replace the original blade cut about 80% of the time and did NOT cut the other 20% of the time. I then proceeded to TEST the OLFA 45mm Rotary Blades, 5-pack blades and found that ONLY ONE new blade out of FIVE cut fabric cleanly. Mind you, I retested the original blade (yes I kept the original blade) and it still cuts a clean edge BETTER than four out of five OLFA 45mm Rotary Blades, 5-pack blades. I am not happy with these OLFA 45mm Rotary Blades, 5-pack blades as they are too expensive to be tossing four out of five in the trash... Not happy, something is wrong with these blades.

Name brand is better! Original packaging, looks like what I would buy in the store. Great price too! I would order these again from these folks.

I use the blades for quilting. Timely service. Well packaged.
