COLIBROX Quilt Cutter Rotary Cutter Blades 45 Millimeter - 10-Pack

They kind of stick together in the case, but I can slide them carefully and get the next one. Don't stick in cutter, roll nice. Like them.

Great cutters and a great value for your money.

I'm thinking it's been about two years since I purchased these oh, and I still have probably 4 that are brand-new in the package. At that price, you cannot go wrong. I was very leery, as I had purchased inexpensive blades before. But these blades have went above and beyond. I'm glad this review popped up for me because I'm going to go ahead and order some more.

I've used only 1 of the 10 and it works perfectly. I cut a dress, a lining. I have a Fiskars Ergo Titanium cutter. These blades are overall thinner than the ones made by Fiskars, so I assume the edge will dull quicker. Contrary to other reviewers , it doesnt seem to matter that the hole in the blade is notched rather than round; as my fiskar blade was round and​ these are notched and they work.UPDATE: I would add that I've been using the same blade for about 3 sewing projects, including linings, and it's still sharp. I most recently used it to cut sequin fabric, as I didn't want to ruin my shears. And these blades cut the sequins (actually pailletes) wonderfully and are still sharp. If I get the same performance out of all 5 blades, I'll give it 5 stars...will have to wait and see.

I was a bit nervous about this purchase as I've never purchased off-brand blades before. If the first one I used is any indication of the rest, I have never had a blade work so smoothly or perfectly and that includes the Fiskar blade when I first purchased my cutter. I will update this post if I have a bad experience with the rest of the blades, but if the first one is indicative of the rest, I will definitely not hesitate to purchase these blades again.

I was slightly skeptical when I ordered these blades, but I figured for the price it was worth the risk. They shipped out quickly and were delivered ahead of schedule in the middle of a Minot, ND blizzard. So kudos there.I just cut through 4 layers of blizzard fleece while applying pretty close to NO pressure to the blade. These blades are sharp! Thank you so much for such great quality at such a decent price. I'm about to order my second set right now!

These blades are sharp, easy to install, and work perfectly. One thing: make sure you are only working with one blade! Two stuck together from the lubricant for me, and I ended up cutting with two blades for a little bit, which shredded my fabric, but that's a user error on my end.

I have an Olfa rotary cutter. I bought these blades as my original blade was becoming dull after cutting through nearly 30 yards of flannel. I changed out to this blade and I was hopeful that my rotary cutter would be back to slicing and dicing fabric--however it was not. There are dull parts of these blades which are so useless they slide over fabric and leave less of an imprint than a tracer on tracing paper. My fabric edges were shredded from my sawing like action which was needed to cut the fabric.When you spend $20/yrd of fabric not having quality tools is more than just a waste. This is my hobby....and I am willing to pay good money to keep it enjoyable - so I will not be buying more of these blades, nor would I recommend them. In fact I would go so far to say ...stay far away from these blades.Men who are trying to do right by the seamstress they love....don't buy these. I assure you they are not a gift you want to give.To the company....I am happy to return the remaining blades at your cost as I am simply not interested in keeping them.
