I have both and use the 60mm mainly because it autocloses when not in use.
The 45mm I have on a mat next to the machine where I use it to cut smaller things after sewing a seam or just do not want to get up to go to the table.

and I cleaned my glasses so I can see that mine is 28mm NOT 38mm :oops:

I have more than one of each size, plus 28mm and 18mm cutters too. Which I use depends on what I am cutting, which one comes to light first and/or which one has a sharp blade in it (or the replacement blades are handy.) <G>
I also have 2 different styles of 45mm cutters in my travel with the travel machine box. <G>

Yeah, I like to have cutters when and where I need them. And try new ones too.

Have fun,

I have both also. 60 was my first and I love her. Someone gave me the 45 and I love him. I use them both because I have a table I cut big pieces on and I have a cutting mat next to my sewing machine. Also when cutting mulitple layers the 60 is much much better.

Don't throw it away! Eek! If it's a Fiskars, just contact them. I had a Fiskars that kept doing that and I contacted them about it. They had me send in a pic of it to them (to prove which model I had) and they sent me a new one, no questions asked.

I have all three and the one I use the most is the 45mm. The next size would be my 28mm for small stuff and I change blades to use on several thicknesses of paper. I hardly ever use the 60mm as it is just too big. I have used it on upholstery fabric, canvas, and such.
