I can't remember when the last time I used any cutter other than my 28 mm, I have 45 mm and 60 mm cutters that are still unopened. I started using the 28mm years ago at the recommendation of Shar Jorgensen and rarely use any other. I don't find that I change my blades any more often than I think I should, if I just made a bed quilt then before I start a new project I would change blades. I really like the 28mm cutter it is definitely my favorite.

Just wanted to say that I thought my blades were going dull really fast and I have a good mat. Turns out my cutting table (one of those white ones like Walmart, Costco, Sam's, etc) has a slight bow when I push down. So I put an extra piece of cabinet we had left from an IKEA kitchen. I'm sure any solid piece would do, over the white table, mat on that, and lo and behold, my blades all last a lot longer with less pushing. I mostly use a 45 mm. although I carry my 28 mm. with me too.

Circumferences:
28 mm: 87.96 mm
45 mm: 141.37 mm
60 mm: 188.50 mm
The smaller the diameter of the blade, the more often it has to rotate to cover a certain distance.
I think whatever is the most comfortable and easiest to maneuver is the one to use.
I tend to use whichever one I find first.
THEN - after I find they are all dull, I finally change the blades.
I have gotten "bad" Olfa blades right out of the package - it would not cut one or two threads -

i use my 60 mm for just about everything, it cuts through as many as 8 layers of fabric and because of the size it covers more distance with each revolution of rather wheel.
I only use the 28mm or 18 mm cutters for tight curves, or circles using my slotted half circle ruler.
