I wouldn't want to use in cutting quilt blocks as it would make it almost impossible to get a good scant 1/4" seam.

Then what is the advantage of having one?[/quote]

The wavy/pinking blade is just another creation of the blade companies.......not necessary for the quilting/piecing process.....I never would use it to cut pieces.....if I did crafty or paper things maybe it would be useful....

[quote=teddysmom]Does anyone have one? Do you like it? Where did you find it?

I have one but had not used it until last evening. I was making baby bibs and was using my pinking shears to trim the seams on the curves...my shears were not cutting well and seemed very stiff. I got out the blade and used it and wow it worked great. So now I have it next to my regular cutter and will use it often to trim my curved seams. I don't remember where I got it, but probably from the Fabric store or maybe jhittlesewing or Nancy's Notions. Now my question is can pinking shears be sharpened?

I also use mine mainly for trimming before prewashing.

I snipped off the corners of fabric before washing it. Fabric was in snarls!!! Maybe if you do the whole edges it would work better.

I bought the blade and it fits in your regular rotary cutter. I love it !

I use it for prewashing and also to cut out applique pieces so they do not fray.

I have one and really like it. I bought mine at Jo-ann's

I like it to cut out pieces that I sew together then turn right side out
i.e. circles used in applique. This creates less bulk in the seams

I bought mine a few years ago at Joannes when they sold them in a pack of 4-5 different blades. Fun Don't use often but glad I have when I need them.
