    My quilting friend were having this very conversation the other day. The blades just dont seem to last long. I have several different mats so don't think that is the problem. Going to pay attention to what they are made from. I wasted my money on the blue blade sharpener. Didn't help.

    I received a new cutting mat for Christmas and my "old" blade cuts very well now. My old mat was not self-healing and had so many grooves in it from repeated cuttings in the same place.

    I've noticed the same thing. I have a new rotary cutting mat and I almost never cut in the same place twice when trimming my blocks. I just put in a new Olfa blade and I'm getting skips over the seams. Second batch of Harbor Freight blades wern't good either. First was great.

    I only use Olfa blades and have no problems. Once a year or so, I buy a 6-pack of them at Joann's when they are half off or when I have a 50% off coupon.

    Has anyone 'oiled' their rotary blades with machine oil? I read recently that they need this maintenance occasionaly.

    I've never heard of that. I'm going to check into it.

    I bought a few blades from Harbor Freight but they didn't seem to last very long. I switched back to Fiskars and haven't had any problems. Before Christmas our Hancock's store had the 5 pack for about $13.00. Sounds like a lot, but before the sale price they were $27.00. The one I put in before Christmas is still going strong.

It would be worth it to me to buy better blades. Anyone know if these come is a 5 pack? I finished the first project and it's still cutting like brand new.
    Martelli blades DO come in a 5 pack.................If you go to their web store on line, and sign up, they have a sale a few times a year where your entire order is 50% off.............I LOVE their blades. They last and last. I stock up on them when the sale hits on that site......

    I agree it may be the mat. My Olfa blades get dull as I have the plastic cutting mat from Joann's and not the nice Olfa Self-Healing mat. I think the blades are weaker now than two years ago when I started sewing, I had two Olfa blades BREAK! on me! They were barely used and I was just cutting through one layer, no pins! That was scary.

    I love their blades too! I have their cutting board too (purchased at an estate sale for $25) and it is smooth as glass!

    I just turned my mat over because I have grooves in my mat, and it's only a couple years old. But I seem to use the same area, so it could be the mat as well.

    I use Harbor Freights works great for me and a lot of local quilters I know. I thought the others were not lasting as long either, so I switched. Maybe it's because I don't cringe at the check out when I buy them!

    I went to the Martelli site and watched the guy cut through 20 or more layers, with ease. I ordered the right handed cutter and 5 blades. The guy said he has had people tell him they have had their cutter for around 3 years and it's still going strong. He also said the way you hold a regular cutter also tends to dull the blade. He said nicking the blade is not the problem, it is the angle you hold the cutter that bends the blade, which you can't really see, but the bend misses the fabric and leaves strings behind on the cut. I will let you know ! Syl

    I find my blades last longer on the new mat I bought at the sew/quilt expo here last summer. It is called Big Mat and it actually comes with a 5-year warranty. It is also made in USA. The surface is extra smooth. www.sewingemporium.com.

    My old mat was an Omnigrid self healing mat and I used to have to change blades quite often. I purchased an extra large Beba mat (the translucent kind) and since using this mat, I am getting a much longer life out of my blades. Of course this was one of the selling points the salesperson touted - which I didn't believe (I bought the mat for the size) but ... she was right!!
    May your stitches always be straight, your seams always lie flat, and your grain never be biased against you.

    I think you are right on. I had thought I needed a new blade and I had a small mat right next to my machine and instead of getting up and wallking over to my big mat just quickly trimmed up something and was amazed at how good and sharp the cutter seemed. So I experimented with different mats, cutters and fabrics and the big mat was the culprit.

    Mine seem to find one spot on a rotation that just won't cut no matter where they are on the mat.

    I use Olfas and they seem to last me a long long time and through several projects. Like quiltstingz says polyester batting and some flannels tend to dull the blades faster. I have found that some of the white plastic mats also damage the blades. For me, a long time is 5 months not 5 years..... I use 60mm for more than 4 layers and 45mm for the other and I buy 45mm in 5pak. They are a little costly but that way I know I have a spare when it's needed, especially when at a quilt retreat!!

    I bought one of these sharpeners from the Grace Company a while back and I love it.

    http://truecut.graceframe.com/cart/s...sharpener.html

    They supposedly sharpen virtually any brand, any size blade without having to remove the blade from the cutter. I have several different size cutters, three different brands and so far it works on all of them. It won't make a blade last forever, but has really helped to extend their life! I just run the blade through the sharpener several times after each project, or any time it feels like it needs it. I only paid $24.99 for mine. If you shop around, I'm sure you can find it for less than the $39.99 listed at the site above.

    There is also a tutorial that shows how to use it here:

    I was just going to say this...I just rotated my big mat (it's 72" X 32") It's a big pain to rotate because of all the bolts of fabric on the wall side of it....but I sure cut better with the "new" surface.

    Mine last and last too. I rarely change a blade and it is usually due to a nick caused by those darn errant pins. I dont do a lot of layers and if doing a Buggy Barn technique with 8 or more layers, I change a blade.

    A good mat is critical and I found out that some fabric with poly or other fibers can actually dull blades. I almost ruined a rug hooking cutter blade with some mixed content wool.

    My favorite blades are Gingher. They are more expensive but outlast the others several times over for me.

    I've been using blades I bought over fifteen years ago. My daughter just bought her first machine and supplies and gave me one of her new blades. After cutting one project, the blade doesn't cut as well as my old ones do. It could be the difference in the steel used by Chinese manufacturers. I know the quality of steel has been a problem in other industries..

    Rotary blades

    I don't seem to have a problem with my rotary blades, and I have cut loads of fabric without changing the blades. Have you checked to see if the blades are put in backwards? That can make a big difference. It's worth a try. Hope you have better luck.
