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

What I disliked about this product is that it is very dangerous to try separating the blades!! They are stuck together like glue and it would be extremely easy to cut yourself badly trying to separate the blades! They should have put something... anything in between to make it easier to get them apart. I fear someone is going to end up in the emergency room from trying to get the blades apart! I had to be extremely careful as I am on blood thinners and at this time, with Covid-19 rampant, it would not be a good time to have to go to the E.R.!

be very careful with these, super sharp

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

Stick with Olfa. I bought some cheap blades, and I got what I paid for. Olfa quality control results in a better product

Gave as gift with OLFA Rotary Cutter. OLFA is a company providing quality sewing and quilting tools. I use and gift their products - just nothing better!

Worked fine. Get dull too soon

So much sharper than Fiskars blades! Good value.

The price is good. I use the blades for cutting my fabrics for making quilts.tgat

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.

These are not original Olfa blades, no way! I will only buy from local stores going forward. Shameful. 8/6/2020-UPDATED REVIEW I discovered the perfect remedy from a sewing blog regarding these blades. Use soft cotton to remove the oil from blade. Wipe blades gently with small amount of alcohol and dry using soft cotton. Blades will perform as expected.
