5 or 6. My favorite is the Tonic Guillotine, 2nd favorite is my Boston Guillotine that I've had since Kyle was in first grade. I was room mom for his class. I cut a lot of xerox copied books for the kids to read.
I have several, but my favorites are the creative memories photo trimmer, the fiskars rotary cutter, and my newest one the Tim Holtz precision trimmer.
I have several - favorites are the small WRMK that trims small things, the Creative memories small guillotine and the new Tim Holtz trimmer (it cuts so nice)
