i like the flat, blue handle Dritz ones--I buy 2 new ones every Jan--one for sewing room, one for long arm room. I like it cause it's large enough that my hand doesn't cramp, the blade is flat and slips under a seam easily, and the flat handle doesn't roll anywhere. I like the Clover brand with a flat handle/blade too, but it's just a bit too small (handle) to do lots of ripping (long arm sometimes requires a great deal of unsewing
)
