Wow I have 3 of the 60 Olfa, 5 of the 45 Olfa, 3 of the 28 Olfa. Then I have a brand new 45 splash haven't opened it yet, 1 45 Fons and Porter, 1 Dritz 45. I think that is it oh wait I also have some of the specialty ones like the pinking blade by Olfa.

I think I have two Olfa 60 mm's (one ergonomic and one not), four (?) 45mm's of differing brands (Olfa, Kai, Martelli, and Clover) and the tiny 28mm Olfa. I use the 45mm's the most, favoring the two tone green Clover one my quilting friend bought me because it has a built in light to light up your cut! Love, love, love that!

I have 3 Olfa rulers-all different sizes. My favorite is the 45 mm. I also have a 45mm that is still in the package but it was demonstrated by my friend because of the easy way to remove the blade. I only use the 60mm when I am cutting thru several thicknesses of fabrics.

Everyone in my quilt group has the Quilter's Select rotary cutter. Once they used mine we went shopping. I do like the pretty color ones, they add some fun.
