I have four: 60, 45, 28, 18. The 60 I use for batting and lots o' layers. The 45 I use most b/c it has the ergo handle, cuts most everything just fine, and the blades are cheaper than the 60s. The 28 I use for small cuts, like those Marti Michell templates, and geting just one square out of a large-ish scrap. The 18 I bought b/c the LQS promoted it for cutting the Marti Michell templates but it really only does 1-2 layers well and dulls quickly so I hardly ever use it.

Same here, i also use the 60 for squaring off after the quilting is done, all those layers...

I have the 28mm,45mm and 60mm. I bought the 60mm cutter when I took a class for the wonky 9 patch(stack and slash method). I needed to cut 9 layers at a time.
I use the 45mm cutter for smaller cutting jobs, such as when I'm cutting half square triangles after sewing from squares.
I use the 28mm when I'm cutting circles or drunkard's path
patches.

I have found uses for all four: 60mm, 45mm, 28mm and 18mm.

I have all three sizes. I only use the smallest one on curves or tight cuts. I do use the 45mm the most, but I use the 60mm for thickest cuts. I use my 45 to cut out clothing patterns too. For me it's much faster. I've been using them since they became available. I've been sewing for over 50 years. Jan

I have several sizes but use my 28mm the most. It seems the most comfortable in my hand.

I have both and use both but don't really think it makes any diffrence which one you use. They do cut the same.

I have a 60, 45,28 and i Think a 15. Use them all for different projects. The 60 I just got so haven't used it much yet - just for large blocks - faster. The smaller ones I have at my machines for cutting the dog ears or for very small blocks.

I have both & use both.

The small one is (I believe) a 28mm and I don't know about the 15. I feel the 28 is great for cutting small pieces and pieces with small curves or circles

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.
