Hobby Lobby has the ones I like. They are very like the ones that I got with my Brother sewing machines. They are small and fit my hand better than most and the blade that goes under the stitches is small. It's probably too small for most people. I have been told that I don't use it properly, so there is that too. I like to cut every 3rd or 4th stitch and then just pull the piece apart. Others hold the ripper and push against the sewing threads as the fabric separates. I am always afraid that I will slash through the fabric. I've only done that once.
