I have a Husqvarna rotary cutter that I bought probably 15 years ago when I went to one of their classes with my sister who has 2 or 3 of their "whiz-bang" sewing/embroidery sewing machines. I just started using it and find that I like it as well as my Olfa cutters. It has a lock on it, but the blade retracts when not in use and it opens when you press down to start your cutting. I also found that it has 2 settings..1 for light cutting and 1 for heavy cutting. I have never seen another Husqvarna cutter, so don't know if they still make them or not.
