I use a 45mm. I do have a 28mm, but don't use it much.

I don't even own a 60mm. I use both a 45mm and a 28mm Olfa ergonomic. Which ever one is handy but I prefer the 28mm.

Lately have been using 28mm cutter as blades are less expensive!

Use all 3 but it depends on the cutting project. The 28m is newest to me but I use it more than i thought I would.

I used 45mm all the time, after watching one of my many quilt shows talked about using 60mm that it covered more ground and this made the cuts shorter, I tired it and have not went back to 45mm.

I use my small one for everything because 'it feels good'.

60 for strip cutting(I think it goes faster/easier...not sure which); 45 for most cutting after the strip cutting; and for an example I am currently cutting and saving 9" apple core pieces and I use the 45 for the outside curve and the 28 for the inside curve....so basically, it depends on the project and what feels most comfortable for you.

It depends on what you area cutting. If it is long straight cuts, a 60mm goes thru multiple layers easily. When I am doing smaller cuts or on my little board, I use my 45mm. Only use the little one for curves.

Thank you for sharing all of the great information.

I use the ergonomic 60 mm when I use the June Tailor shape cut (I buy the blades when JA's has a sale or coupons). I also use it for cutting more than 4 layers or very heavy fabric -- it just seems easier. I use the ergonomic 45 for trimming or cutting single layers. I use the 28 for cutting curves and the 18 for ripping out seams.
