    Rotary Cutter Blades

    I put in a new blade to cut a crib size quilt. At the end of the cutting, the blade appeared to very dull. I should think that the blades should last longer than that for what they cost. I am using an Olfa cutter and blades. Have any of you experienced this? Would you suggest I use a different rotary cutter?

    Try going to the Olfa website that is listed on their packaging. I think it is really just Olfa.com. They have videos showing how to replace the blades in their different cutters. Now I thought I didn't need to do that because I have been replacing these blade for about 5 years, but all of a sudden my blades were going bad really fast. So out of frustration, I decided to look at their video and wouldn't you know, I was not doing it correctly. It was a very simple fix after I watched that. I think because the blades actually last so long, I forgot how to replace them, even though I thought I was following the diagram on the package. Something about seeing it done just clicked for me. Good luck.

    I have replaced the blade several times and all was fine. There is no way to replace them incorrectly with the quick release. You simply release the blade by sliding the lock on the back of the handle. Put new blade in and re lock.

    Are you sure you just have one blade? They are notorious for sticking together. Be REALLY careful, but try to slide them apart and see if you have 2. Could be your mat too. Ask me how I know!

    Yes, a blade should last longer than one small quilt, but some of them just aren't machined as well as others. There could also be another factor working against you, such as a mat that needs replacing, causing you to press harder on the blade than you should.

    Thanks for the input. I've checked the blade, only one. My mat is relatively new. So that should not be the issue. I've contacted Olfa directly so I'll patiently wait for a response. In the meantime I've put a new blade on the cutter and all is well.

    There is a really good tool out there called TrueCut. It sharpens 3 sizes of blades. I haven't bought a new blade in over a year. A blade can be resharpened several times. The cost of the sharpener will be covered fairly quickly if you use rotary cutters a lot.

    I have to remind us that there are many mats out there that *will* dull your cutting blades pretty fast. Fiskars gray mat is one; there are others. If you are using Olfa blades and cutters, it's worth your while to use the Olfa mats too, which were specifically designed for use with their cutters.

    After switching to The Big Mat (www.sewingemporium.com), my blades last a lot longer now. I've used the white mat sold by Joann Fabrics; it seems to be an off brand. The surface is somewhat rough. It does cause the blades to get dull very fast.

    Same as myself. We have some personalities born in 1948 including Sooty oh and Prince Charles. Good year to be born

    Rotary cutters. I followed instructions on the pack and started cutting. I am ambidextrous and until I went to class and my friend went to use mine and said your not left handed. I had managed to put it all together for left handed . I was cutting left handed because with right hand not good and I didn't realise I was doing it.

    I find that I need to replace my blade more when using batik I assume because of the tight threads. Since dad died I have to buy more he used to sharpen then or me.

    The link looks the same, but I got this one from Startpage (Google). You need to enable javascript. Think it could be one of the tracking apps that messed up.

    I had a big mat. It did all right until I went to clean 505 off of it. The blue lines came off. I bought a Martelli at a show.
    Larger mat (extra borders) for same size. Much thicker. I'm using a Truecut holder and either Olfa or Fiskers blades. Just bought some titanium, but haven't tried them yet.

    Olfa does OK.

    Have you considered that the dulling might be caused by your mat needing Mat Care? It is recommended by manufacturers. They get a lot of abuse in cutting and do need to be refreshed. Thanks for asking the question. Mine really needs a wipe down or bath.

    Hello, I found my blades were getting dull fast too. My mat is cut up so I'm in the market for a new one. I had recently purchased a rotating mat for trimming blocks down and it had a self-healing mat. My blades seem to love it and don't get dull as fast and cuts so much better. I found a place that will cut the self-healing mat to fit whatever size you need so I'm saving my pennies for it. Until then I'll just have to use what I have.

    I had that happen with a pkg of Fiskars. I think sometimes you just get a bad batch.

    Go to Harbor Freight and buy their blades, they are 2 for 2.99 and last as long as the expensive ones.

    I will tell you I have had no more problems with blades dulling early since I switched to Martelli blades and the Martelli mats!...I wait untill they have their Redlline Sale twice a year when everything is 50% off - and I stock up then. I believe they are the BEST blades and mats..........and with the cost of quilting cotton ever increasing, I cannot afford not to use the best blades and mats I can get..........

    I've tried Harbor Freight blades and they were horrible. Couldn't even cut one layer. I've heard people say they had good luck with them. I think that different Harbor Freights have different blades.. it has to be something like that for some people say they are good and others that they don't work at all.
