I have all 3 sizes, but I primarily use the 45mm. I prefer pressure sensitive cutters so I don't have to open or close the blade. It's retracted when not in use, and ready to cut when I need it.

I use 45 mm one almost all the time. I bought one of the new ones with ball bearings which was easier on the wrist, but it came loose after using for a while, and I had to re-tighten it. So I went back to my Fiskars one. I also have an Olfa 28 mm one that I use mostly for curves. It seems sharper but maybe that's just me. I have a small 6" x 8" mat that I use to cut borders when layin out my quilt on the ironing board, and for that I also use the 28mm cutter.

I have at least three 45 cutters (all the same brand) and one 28 cutter that I've only used once or twice. Blades don't last as long as they once did, I may get two quilts out of a blade if I'm lucky. Anytime they are on sale i pick up another pack or two just to have on hand.

I like the retractable yellow cutter, Olfa? I drop mine a lot and used to ruin the blade. I need the 28 mm for curves. I just use scissors.

Famore does make a 60mm. I just looked on their website - it's sold out. They also have a 28mm.

I also love my Famore. I've had the 45mm for a while and just bought the 60mm from Linda's Electric Quilter. It arrived last Saturday so I've only used it once but I think it will be great.

Oh, thank you, Sewgood! I hadn't looked at their site in a while. I'll have to check and see if I can get one when they come back in stock.

I just ordered a 60mm cutter and 2 pack of blades. I can hardly wait to get it!

I found years ago that the blades seem to last longer on the self healing mats. Also, flip your blades as you can get a bit more out of them that way. I have a blade sharpener so I get a bit more life out of them that way also. Once I've sharpened them once, I sharpen them one more time to use for cutting paper only. I have my rotary cutters marked for either fabric or paper so I don't get them mixed up.

Also, I use the 60mm most times. But whatever size you use, be careful. Yesterday I thought it would be great to try to slice a bit off on my right index finger. Bled like a stuck pig. You don't realize just how much you use your index fingers until you can't. Luckly it was my right index and I'm left handed but still troublesome like trying to type right now or use the pc mouse.

Also, try the titanium blades, I think they last much longer and less expensive too. Think I ordered tehm on Amazon.

I just remembered I tried one of those with the ball bearing. It doesn't work any better for me than the Olfa yellow one.

Famore makes Missouri Star rotary cutters. They have the ball bearings. They are on flash sales often.

A knife sharpener told me, always sharpen a sharp blade and you never will have a dull blade.
I use the Grace vertical sharpener, run the blade through a couple of times before using. I rarely change blades for dullness. The 28 and smaller cutters make more accurate cuts because the smaller blade does not push the fabric forward as much as the bigger blades. Learned this from Pauline from Pauline's World. I use the Clover 28 size by my machine for quick cuts.
