    These blades are easy to replace. Amazing how much better a sharp blade cuts through layers of fabric. I always keep a supply on hand.

    Only Olfa cutters and blades for me. You get what you pay for. These are for my business, and fooling around with cheap blades and cutters is a waste of time, and dangerous. If you buy an Olfa cutter, USE the Olfa blades.

    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.

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

    I like the blades and use them for quilting. They work well for me and seem to be better than other brands.

    So sharp! Easy to change out and replace in my 45mm rotary cutter.The case is nice to have to store and dispose of the used blades. Cuts through several layers of fabric like a dream!

    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
