I use my 28 often when needing a seam ripper especially on larger pieces and for curve cuts.

yes, but do you have the 28 rotary cutter itself? those blades will not fit the 45. I use the 45 almost all the time. i tend to pick up my 28 when ripping out seams but not for much else.

I use the 45 almost all the time. i tend to pick up my 28 when ripping out seams but not for much else. the blades were on the rotary cutters, so 2 Sets for $10 . Even if they get dull faster, still a good deal.

I have 3 different sized cutters but mainly use my 60 mm cutter. I find it more comfortable as I have arthritis in my hands . I bought the 28 mm when I bought my wavy rulers but so far haven't used them. (Note to self :- look into this.)
I also have a couple of 45mm cutters. One is my original Kai cutter as well as another Kai with an ergonomical handle which is comfortable to use.

I love my 28mm cutter, I use mine almost all the time. The only time I resort to my bigger cutters is when I am cutting several layers at one time, which isn't often. I still use my 28mm for cutting my FQ's for quilts. I love it.

My first rotary cutter was a craft kit. Small mat and the 28 cutter. I used it a long long time in my sewing. I didn't know there was a bigger size :). It was great!

I don't know why many think a cutting mat will last for years and think it's still good. It dries out, the bonding becomes brittle, and the surface deteriorates. I have all sizes of rotary cutter. I recently tried the new finger rotary cutter and it's great for intricate shapes.

Interesting topic!! Fairly new to quilting, I only have the 45mm. I have never given any thought as to why and the differences between sizes, but now I'm going to purchase a 28mm and give it a try. Love this Quilting Board. I learn so much from everyone. Thanks :)

28 mm is the only cutter I use. I own 18mm (never use), 45 mm (very seldom used) and a 60 mm (too big and clumsy of me). I have small hands (about the only part of me that is small!:D) and find I can control the 28 mm much better than the other sizes.
