    I just got this order, but we use this brand all the time. Theyre sharp and the edge lasts a reasonably long time.

    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 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.

    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 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
