What a difference a blade makes....
#3
Usually when I am starting a brand new big project, I replace my rotary blade. I figure that if I am using $150 - at least - on fabrics, then it is worth the couple of dollars for a new blade. Same thing with my needle, new project, new needle. And large projects have the needle replaced during also, sometimes more than once.

Yes, it does make a huge difference! I've just changed mine after having to use more and more pressure for quite a while... Frugal me just wanted to keep on using the old one - but now that I have changed it, it cuts sooooo smooth!

I used to rarely ever change them, but eventually it started cutting such jagged lines that I was wasting fabric, so I caved and bought new ones. Oh, wow, was I ever happy!!! Since I do a lot of small pieces for applique on my quilts & basically only use my scissors to cut the backing fabric, it ends up that I change it out for every yard or so of quilt. Soaking my cutting mat helped them last a bit longer. Wish I'd known that trick earlier on since some of the cut marks don't come out (prob also due to using such a dull blade that I had to apply a lot of pressure to get my cuts).
I figure I change my blades on about the same schedule as my needles -- every 8 hours or so of use.
Oh, and btw, I have a 28mm Olfa. It came in some quilting kit I got years back & I haven't seen the need yet to move up to the next size, but that probably affects how often I have to change them since my blade has to go through 2-3x the number of rotations of the larger rotary cutters.
