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

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.

These blades are terrible. This was the first time I bought new blades for my rotary cutter. I noticed it was starting to skip over a couple of tiny threads on the fabric I was cutting so I figured it was getting a little dull. I purchased these blades because of all of the good reviews that customers have allegedly left for it. The first blade I used seemed to work great at first. But after 2 projects (sewing clothes for my daughter and me), it started to dull a little. No problem, I figured I needed a new blade every project or two anyways. I switched out my blade to a brand new one from the package. That one was HORRIFIC right from the start. It's skipping over large chunks of my fabric, I can actually feel it bumping at regular intervals as I pull the blade over my fabric. I'm afraid I may have ruined my current project because my cuts are so terrible. This "brand new" blade from the package is actually worse than my old one that came with my rotary cutter that I had used on multiple projects. Do yourself a favor, and do not order these blades.

I normally purchase the "Olfa" brand 45mm rotary blades. I decided to give these a try because of the huge difference in price. I would say that this is one of those times that you get what you pay for. The blades are okay for someone that only cuts paper, but for those of you that use these to cut fabric then I would suggest another brand of rotary blades. They do cut but wear out quickly and end up skipping when cutting out fabric pieces. I just put in a new blade and the first cut felt like I had run over a pin which I didn't. Pressing hard when cutting with a back and forth motion will cut down on the skipped fabric but will shorten the life of your cutting board. Overall, this blade is just not worth it even for the cheaper price as it is prone to faults and wears out quickly.

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!

Fiskars OEM blades, as mentioned in the questions above, have a round hole. These blades have notched holes. I didn't think it would make a difference since the listing says "Fits Fiskars". You'll see a lot of reviews here talking about how the blade is nicked or dull and is skipping in the fabric. The blade itself is fine. It's the fact that the hole is slipping around in the rotary handle, falling into the notches when it should be rolling smoothly. I would not recommend this if you are replacing a Fiskars blade.

I purchased two paks of these blades. The top 6 blades were wonderful and cut well. The last 4 blades had a flat side and wouldn't cut when the blade rolled along the flat side. I didn't find this out until after I had purchased a second pak.Pretty shoddy business practice!

I desperately needed these to make a whole bunch of masks for the Coronavirus pandemic. Unfortunately, the blades turned out to be horrible. They cut so poorly, that I have to go back over each piece and re-cut with scissors, resulting in shredded cloth. There seem to be spots on each blade that are not sharp, so when you are cutting, it has a jerky-jerky quality. The whole package was like this.

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.
